This guide will take you through the relevant steps so that you will be able to make the most of your LogTag products. The guide is structured into chapters that will guide you through the process of installing the software, using the LogTag products and lastly some of the options that are available to you for making your efforts and experience of using the software as efficient, effective and pleasant as possible.

The chapters in this guide are placed in an order that you will need to follow in order to successfully use the LogTag products first time. Experienced users of the software may choose to skip the first two chapters. However, if you are about to use a newer version of a LogTag and/or Interface Cradle, we recommend you at least skim the installation chapter for any relevant changes that should be performed prior to using your new version of LogTag hardware.

This guide covers all the features included in version 2.0 of the LogTag Analyzer software. The chapter "Finding your software version (on page 140)" included later in this guide will help you through the process of finding out what version of the LogTag Analyzer software is being used and will help explain and determine if this version of the guide refers to the version of the software being used. The chapter "Getting updated software (on page

138)" included later in this guide will help you through the process of obtaining an updated copy of the software. Therefore, if you find a feature described within this guide that does not appear in your software and/or a feature within the version of software being used that is not described in this guide, then we recommend you obtain a newer version of the software and/or a newer version of this guide. You may obtain a free online copy of the latest version of this guide from the LogTag Recorders Internet site, www.logtagrecorders.com.

Although this guide includes all the relevant information to install and use the product range supplied by LogTag Recorders, there are at times an expectation that the reader is familiar with using their computer and the Windows® operating system. If a feature of the software is specific to a version of the Windows® operating system, the guide will indicate appropriately for you the relevant differences.

Feedback, positive or negative, about the software, the LogTag products and/or this guide is welcome. If you believe the products could be improved, you are welcome to send us your comments and we will do our best to include the improvements in a future release.

Introduction

To make use of your LogTag you will need to first install the software on your computer. This will allow you to prepare your LogTag(s) for use, retrieve the readings the LogTag(s) have recorded, and analyze the data. This chapter will take you through the steps necessary to successful install the software on to your computer so you can begin using your LogTag(s). The process of installing the LogTag Analyzer software should be very familiar to users that have previously installed other software and therefore some experienced users may choose to only skim read or entirely skip this chapter. If you are new to using a computer and/or unsure about installing the software, we recommend you read the remainder of this chapter.

If you are unsure of what your computer specifications are, please read the section about "Finding your computer specifications (on page 144)", which will help you locate the relevant information.

Getting a copy of the software

The software is available for download from the LogTag Recorders Internet site, www.logtagrecorders.com. LogTag Recorders does not charge for the download of the LogTag Analyzer software or for the updates to the LogTag Analyzer software. You are welcome to distribute copies of the LogTag Analyzer software provided it is distributed in the packaged format as originally downloaded from the LogTag Recorders Internet site.

Chapter 2 Installing the software 9

When you visit the LogTag Recorders Internet site, follow the software navigation links to obtain a download link for the latest version of the LogTag Analyzer software. The request to download LogTag Analyzer software from the LogTag Recorders Internet site will result in an e-mail automatically being sent to you with the download link for the latest version. To begin the actual download of the software process, click on the link provided in your e-mail, and your e-mail software will prompt you to save or open the file.

We recommend choosing the option to save the file to your disk and to save the file to your desktop. If you are an experienced user you may wish to save the file to a different folder of your choosing. Once the installation process has been completed, this file can be safely deleted, as it is not required for using the software.

Only one file needs to be downloaded to enable installation of the software on your computer. Once the relevant installation file has been downloaded to your computer, you only have to open the file to begin the installation process.

The installation process

To install the LogTag Analyzer software, first you need to locate the installation file that was downloaded from the LogTag Recorders Internet site. To begin the installation process open the installation file, which is typically performed by double clicking the left mouse button.

Tip: Double clicking a mouse button, implies the user clicks the same mouse button in quick succession.

The installation process will guide you through the relevant steps to correctly and successfully install the software. If you have installed any other software, you should find the installation process familiar. To proceed through each step of the installation process, click the "Next" button. If you want to change a previous step you can click the "Back"

10 LogTag Analyzer User Guide (2.0)

button. When the process is ready to be completed, clicking the "Finish" button, when it appears, will finish the installation process. If you want to stop installing the software, click the "Cancel" button.

We recommend you leave all options to their default setting, especially if you are unsure of what option to select or what the actual implications are if the option was to be changed.

The drivers required to operate your USB interface are installed as part of the main installation process. From time to time updated drivers may be released by LogTag Recorders. If you are operating on Windows XP or Windows Vista these drivers will be available through the Microsoft Windows ® Update feature, as an optional hardware update.

Upgrading from earlier versions

If you are installing a newer version of LogTag Analyzer on a computer, which already has an earlier version installed, the old installation will be replaced by the newer version.

Any previously installed unsigned USB drivers will not be replaced automatically. To replace the USB drivers you will need to go to Windows Update and select the FTDI - USB Interface update from the "Other hardware" section.

Please refer to your Operating System manual or help on how to access this feature.

You can also update your driver from the Control Panel device manager. Please see

Resolving USB Driver Problems (on page 151) later in this document.

Chapter 2 Installing the software 11

Note: LogTag Recorders do no t recommend updating your LogTag Analyzer software manually. Instead, you should be using the automated update function, which ensures you only use the version with the same character set as the one already installed. Manually updating a version with the standard character set by installing the version with the Unicode character set -or vice versa- may produce unwanted and erroneous results, especially where passwords are affected.

Starting the software

At the conclusion of the installation process, the final screen will provide you with an option to immediately start the LogTag Analyzer software. If the option "Start LogTag Analyzer after finished" is not visible, then you require other newer software, for example a newer version of Microsoft Internet Explorer, to be installed prior to the LogTag Analyzer software being able to successfully start.

The installation of the LogTag Analyzer software will also provide you with two simple methods to start the LogTag Analyzer at a later time:

12 LogTag Analyzer User Guide (2.0)

1 A "Shortcut" on the desktop, which you can double click to start the software.

2 A "Shortcut" in the "Start" menu system.

If you are using Windows XP, you may need to click on the "All Programs" item to locate the "LogTag Analyzer" shortcut, like in the following picture.

If you are not using Windows XP, you will find the "LogTag Analyzer" shortcut in the "Programs" menu, in a similar location to the following picture.

You've got the software installed on your computer and now you want to use the LogTag, see how it goes and what it can do. This chapter will briefly cover the steps involved to get your LogTag ready to use, how to get it started and then retrieve the recorded information out of the LogTag. The subsequent chapters will explain in more depth these steps and the various options available to you.

Quick Start Guide

14 LogTag Analyzer User Guide (2.0)

Connecting the Interface

There are two types of the Interface Cradle available. The first connects to the computers serial (RS232) communications port and the other connects to the computers USB (Universal Serial Bus) communications port. Although there may be multiple connectors on the computer for each of these types of communications ports, the shape of each is unique and therefore it is not possible to connect the Interface Cradle to the wrong type of communications port. The software supports the connection of multiple Interface Cradles at the same time and therefore as many serial and/or USB Interface Cradles as are needed and the computer supports may be connected.

The connectors for the serial (RS232) communications ports typically look like the following picture.

Serial (RS232) communication ports can be typically found at the rear of the computer and there are usually at most two ports installed on a single computer. Most serial Interface Cradle connectors will have screws included on the plug and as such we recommend that these are tightened when the connector is plugged in so that it does not accidentally pull out during usage.

The connectors for USB devices typically look like the following picture.

Connectors for USB devices and the sockets on the computer where USB devices are plugged in will often display a USB logo nearby to help them be identified. Example pictures of the USB logos that may appear are:

Chapter 3 Quick Start Guide 15

The sockets for the USB communication ports are typically located at the rear of the computer. In some computers there may also be two or more USB communication ports located on a front panel of the computer and/or on the top of the computer case. Please ensure that the software has been installed prior to connecting the USB Interface Cradle to the computer as the software installation also installs the drivers required to successfully connect and use the USB Interface Cradle. If you experience problems getting the software to find and identify a connected USB Interface Cradle then there may have been a problem during the installation of the software with the installation of the drivers that the USB Interface Cradle requires. The subsequent section resolving USB

driver problems (on page 151) will guide you through the steps necessary to resolve any

problems with getting USB Interface Cradles working on the computer. If the computer is using the Windows NT

operating system, a USB Interface Cradle will

not be able to be used, as Windows NT

does not support USB devices.

Using the LogTag with the Interface

The LogTag fits into the Interface Cradle slot with the front of the LogTag facing towards the front label of the Interface Cradle with the contacts on the reverse side, similar to the following picture.

If you look into the Interface Cradle slot, you will be able to see where the contacts connect with the matching contacts in the Interface Cradle.

When placing the LogTag into the Int erface Cradle slot, you should be able to feel a very slight resistance as the contacts "grab" the LogTag. This is normal. Removal of the LogTag will cause a slight clicking noise as the contacts snap back into their "unloaded position".

16 LogTag Analyzer User Guide (2.0)

If the LogTag has readings stored within its memory, the software will automatically start to download the data and will also display an animated picture during the download process, similar to the following picture.

The download process can be stopped by clicking on the "Cancel" button below the download animation or by pressing the "Esc" key.

Get a LogTag ready for use

To begin the process of preparing a LogTag to record information, first click the LogTag icon (

) that is located on the toolbar (see "Menus and Toolbars" on page 117), which will

start the LogTag wizard.

The LogTag wizard performs two distinct tasks: 1 It finds the communication port (USB and/or Serial) that the LogTag is attached to

through the Interface Cradle and retrieves the data that is stored within the LogTag, and

2 It allows the LogTag that is currently connected and in the Interface Cradle to be

prepared for its next use.

The wizard is a key part of the software that is used for each of the steps.

Chapter 3 Quick Start Guide 17

Welcome

First the Wizard has a welcome screen (this is "1" on the Action List). This asks you to make sure you have not neglected to place the LogTag firmly in the Interface Cradle.

The Wizard is responsible for certain "Action Steps" and these are clearly listed at the left in the wizard window.

To get to the next screen, click on

and the next wizard screen will appear.

The green arrow will indicate you have moved to Step 2.

18 LogTag Analyzer User Guide (2.0)

Locate LogTag(s) download and save relevant data

In this screen you will see one of the following pictures next to each of the items in the list:

 (no picture) indicates the software is still using this communications port. 

Data was successfully retrieved from the LogTag and stored/saved to disk.



Data was successfully retrieved from the LogTag but there was no need to save

the information to disk.



The software was unable to detect an Interface Cradle connected to the

communications port or was unable to detect a LogTag in the Interface Cradle.



The LogTag is a single use logger and cannot be prepared for use again and should therefore be returned to the supplying distributor or agent once you have finished with the LogTag. You will still be able to continue to retrieve information stored within the LogTag.

The LogTag should be almost instantly recognized by serial number and the number of readings. It is possible to have and use more than one communication port at a time and if so, the wizard will find all the LogTags.

Chapter 3 Quick Start Guide 19

The communication ports that are not in use (the ones that initially are reported with the

mark) ca n be remov ed from view by selecting an option (see "Communication Ports" on page 113). You don't have to do that now, but you can do it later to clean up the "wizard window" appearance.

To get to the next screen, click on

and the third wizard step screen will

appear. The software will automatically proceed to the next wizard step, as if the user clicked on

, if each of the Interface Cradles detected have a LogTag detected

in them and the information within the LogTag was successfully retrieved.

Configure LogTag(s) for next use

The options are available so you have appropriate control over the way the LogTags will behave and store data for the upcoming period of recording. These options are explained

20 LogTag Analyzer User Guide (2.0)

in more detail in the chapter "Preparing LogTag for use on page 26". Click to record the configuration data and you will see the final confirmation screen.

Prepare LogTag(s) for next use

The last Wizard screen involves sending the new configuration data to each LogTag to prepare them for their next use. While the software is sending the new configuration data to each LogTag the top of the window will look similar to the following picture. The process of sending the new configuration data to each LogTag should take less than 20 seconds in total to complete.

Chapter 3 Quick Start Guide 21

Once the software has finished uploading the updated configuration information into each LogTag, the window displaying the progress will look similar to the following picture.

In this screen you will see one of the following pictures next to each of the items in the list:

 (no picture) indicates the LogTag is still in the process of being prepared for its next

use.



The LogTag was successfully prepared for its next use.



The LogTag failed to be prepared for next use. Press to try again.



The battery within the LogTag is low and is unlikely to have enough capacity to record all the data you want during its next use. In this situation the LogTag should no longer be used.

When all LogTags have finished receiving their new configuration data, click to close the wizard. Your LogTag(s) are now ready to be started and used.

Please note that the automatic download feature is disabled in this screen. If you use the

button to configure a different LogTag, you may update the configuration of

a LogTag with unsaved data.

22 LogTag Analyzer User Guide (2.0)

Starting and using the LogTag

Once a LogTag has been successfully configured for use it is ready to be started. There are two discrete methods available to start a LogTag recording, which are selected during configuration. These start methods are explained in more detail in the chapter "Preparing

LogTag for use on page 26".

1 By pressing and holding the START MARK button on the LogTag until both the OK and

Alert lights alternately flash on and off.

2 By waiting until the date/time defined during configuration is reached, at which time

recording will automatically commence. Pressing the START MARK button will have no effect until recording has commenced.

You can also have the LogTag record an "inspection" mark at any time while it is recording, simply by pressing and holding the START MARK button on the LogTag until both the OK and Alert lights flash on and off at the same time. You may have the LogTag record as many inspection marks as you want while it is recording, however only one inspection mark can be recorded per reading. In other words, if your LogTag is configured to take readings at 15 minute intervals, inspection marks can be recorded at intervals of 15 minutes or more. If the LogTag has finished recording then pressing the START MARK button will have no effect until after the LogTag has been prepared for next use.

Once the LogTag has started recording (either via Start button or date/time start) the Alert and OK indicator lights operate in the following manner:

Red 'Alert' light : Flashes every 4 seconds if a configured alert condition has been met and/or exceeded.

If an alert condition is still present at the end of recording then the Alert light will continue to flash at the same rate.

Green 'OK' light: Regularly flashes every 4 seconds while recording is active to indicate that no alert condition is present.

If recording is complete and no alert condition is present then will flash regularly every 8 seconds.

Chapter 3 Quick Start Guide 23

Only flashes if no alert condition is present.

24 LogTag Analyzer User Guide (2.0)

LogTag light patterns

The LogTag's LED's signal a number of different events or status information. The table below contains a summary of the light patterns you may come across during use.

Signal Sequence Occurrence

LogTag wake-up signal

Sequence of four alternate flashes of green-red LED’s

 displayed after configuration has been

successfully applied to the LogTag.

 when a LogTag is woken up from hibernation (see

"Prolonging battery life" on page 45) state. Not to be mixed up with...

LogTag start-up signal

Sequence of sixteen alternate flashes of green-red LED’s

 displayed when the LogTag starts its recording

cycle.

Mark signal Sequence of five

simultaneous flashes of green and red LED’s

 displayed when pressing start/mark button while

recording to indicate an inspection mark in the software.

 displayed directly after the start-up signal

following a push button start where a recording delay has been configured. In this instance the start-up signal is repeated when the actual recording begins.

Logging active, no alert present

Single flash of green LED every 4 seconds (approx.)

 indicates LogTag is recording.

This is not displayed when pre-start is active and the main logging cycle has not yet started. It is also not displayed when the green LED has been turned off in the configuration screen.

Logging finished, no alert present

Single flash of green LED every 8 seconds (approx.)

 indicates LogTag has finished recording.

This is not displayed when the green LED has been turned off in the configuration screen.

Will also be displayed when unit has been woken up from hibernation.

Chapter 3 Quick Start Guide 25

Alert condition present

Single flash of red LED every 4 seconds

 displayed when the LogTag has detected an alert

condition (see "Alert Processing" on page 34) and

the Alert LED has been activated If an alert is present you cannot determine if the

unit is still logging or has finished its log cycle. It is more important to ensure an alarm condition is not overlooked, and 8 seconds are to long a time to still achieve that.

If the Alert LED has not been activated during configuration, in essence the visual indicators have been disabled, and the green LED will flash every 4 or 8 seconds as above.

Communication The green LED will

flash occasionally

 during communication with the interface the

green LED will flash occasionally; no information is conveyed in this.

Start button press

red LED glows faintly

 This is by design but conveys no information.

Retrieve information from LogTag

When you are ready to view the recordings that are stored within the LogTag, just place the LogTag into the Interface Cradle as before. If the LogTag is still recording when you go to retrieve the readings it will continue to record without interruption so you will be able to download again later if you choose.

If the LogTag has readings stored within its memory, the software will automatically start to retrieve a copy of the recording contained within the LogTag and will also display an animated picture during the download process, similar to the following picture.

Once the readings have been successfully retrieved from the LogTag(s), the software will display the information for you. The chapter "Results from LogTag (on page 47)" explains in more detail the information that is displayed to you as a result of retrieving the recorded readings from LogTag(s).

Before you can use a LogTag to monitor and record environmental conditions you must first prepare it for use. The process of preparing a LogTag for use allows you to define a number of parameters, including:

 How long it should record the environmental condition for, so that you can be assured

that it will record for the duration of time required. For example, if you want it to monitor a shipment that will take 10 days to deliver, you will be able to make sure it will record the humidity and/or temperatures throughout the entire 10 day period.

 How often it should record the environmental conditions.  Under what conditions it should display an alert. An alert indicates when the

environmental condition being recorded is not within set limits.

This chapter explains how to prepare a LogTag for use and what the options mean.

Preparing LogTag(s) for use

Chapter 4 Preparing LogTag(s) for use 27

Getting a LogTag ready for use

There are two ways to prepare a LogTag for use, both of which will achieve the same result. Once a LogTag has been through the configuration process to get it ready for next use, any readings previously recorded will no longer be available for retrieval.

1 Click the LogTag icon (

) on the toolbar or the "Wizard..." menu item located in the

LogTag menu.

This is the safest option, as it will retrieve any readings that are stored within the LogTag and save them to disk before getting the LogTag ready for next use. This option is useful when you are unsure whether or not the readings stored within the LogTag have been previously retrieved and saved to disk.

2 Click the "Configure..." menu item located in the LogTag menu.

This is the quickest option, as it does not involve the step that retrieves any readings that are stored within the LogTag. This option is useful when you know you have previously retrieved the readings or you no longer need a record of the readings that are currently stored within the LogTag.

The wizard will appear once you have selected the option of your choice to guide you through the necessary steps to prepare a LogTag for next use. While the wizard is visible the "Automatic download" feature will be disabled.

28 LogTag Analyzer User Guide (2.0)

Restricted Access Requirements

Every LogTag supports an option that, when enabled, results in users being required to provide the correct password to gain further access to the LogTag. When the restricted access option is enabled, a window similar to the following picture will be displayed allowing the user to enter the correct password.

The relevant process and/or wizard will only continue successfully if the correct password is supplied by the user. Passwords are case sensitive and therefore the passwords "Bob" and "bob", for example, are different.

Various models also offer the option to also request a password when the logger is downloaded. This function is enabled when configuring the logger by ticking the box next to "Download requires password":

Some models do not have this feature enabled and can be upgraded, so a password can be requested on download. In this case a further check box appears on the configuration screen:

The tick box "Download requires a password" is greyed out if the update has not previously been applied to the logger being configured. Once you tick the "Update logger to enable this feature" box, the "Download requires a password" box becomes available for activation. You can then select the password functions for either configuration or

Chapter 4 Preparing LogTag(s) for use 29

download. The logger will be permanently upgraded as soon as the configuration is downloaded.

Following should be noted:

 The update cannot be reversed.  If the "Update logger to enable this feature" is ticked, the upgrade will perform,

regardless whether any of the "...requires a password" tick boxes are enabled or not.

 If multiple units are configured at the same time using more than one interface, all

units will be upgraded if the Upgrade option is selected.

 If this upgrade is applied, LogTag Analyzer 1.8r9 or later will be required to access the

loggers. Older versions will display an error message if communication is attempted.

 When the "Again" button is used with a different unit, that unit will also be upgraded.  Data files cannot be protected by passwords.  If a unit has been upgraded in a previous session, and is now configured using the

"Download requires a password" function, units configured with the "Again" button in the same session will not automatically be upgraded; only those units that have already been upgraded separately in a previous session will have the "Password on download" function enabled.

Preparing LogTag for next use

The "Configure LogTag(s) for next use" step provides you with all the options that can be configured to effect how a LogTag records data during its next use. Once the changes

within this screen have been made, if any, click

to send the configuration

information to the LogTag(s).

The following table describes each configurable option that is permitted to change.

Function Purpose

User ID This can be used for identification of the load in transit to be

monitored, or simply an identifier that describes the purpose of the monitoring. Bill of Loading information, Shipper, commodity, contact name and other relevant information can be placed here.

Chapter 4 Preparing LogTag(s) for use 31

Start method This is used t o determine how/when the LogTag will start recording

its next set of readings.  Push button start

When the 'Push button start' option is selected, the LogTag will start recording when the START MARK button has been pressed and held until both the OK and Alert lights alternately flash on and off. If pre-start recording is enabled, the LogTag will start logging pre-start readings immediately (see section "Pre start

data collection on page 42").

 Date/Time start

When the 'Date/Time start' option is selected, the LogTag will automatically start recording at the date/time defined in the subsequent field. Pressing the START MARK button prior to the start date/time will have no effect. There will be no pre-start readings recorded prior to the start date/time.

Note: When using the Date/Time start option, the earliest start time that can be selected is two minutes after the current time. This delay allows you to complete the remaining configuration options and gives the software enough time to configure the LogTag before it starts.

 Push button start from hibernation

When the 'Push button start from hibernation' option is selected, the LogTag will start as if programmed for 'Push button start'. The difference is that once the configuration is successfully downloaded to the LogTag it will be placed into hibernation. When the START MARK button has been pressed and held, the LogTag will wake from hibernation and start recording with the parameters as configured.

 Please note in this mode the real time clock inside the logger is

not active. It is therefore vital that the computer on which the unit is downloaded is set to the correct time.

Please see Prolonging battery life (on page 45) for more information on Hibernation.

Not every LogTag model can support every start mechanism. As a result, specific options may not be be listed when configuring a LogTag.

Enable pre-start logging Pre-start logging is a feature that protects the recording in the

event of a failure to actually press the START MARK button to initiate the recording. It is an insurance policy against the loss of critical data. This is almost always checked for transit monitoring applications. This option is further explained in the section "Pre

start data collection on page 42".

Record readings continuously, overwrite oldest when memory full

This is what is called a "data wrap" in which the recorder just keeps writing data to memory. It is a "moving window" of data. For example, this is useful for fixed base MKT monitoring with the interval set to one year, so that the current "yearly MKT" can always be in the memory of the LogTag. If this option is selected, the user will be "opted out" of the next two options. This option is further explained in the section "Continuous operation (on page

43)".

32 LogTag Analyzer User Guide (2.0)

Record readings so that:

If this is selected, the logger stops logging when the number of data points has been gathered and stored in memory that spans at least the number of days specified below. When this option is selected, the following two options will determine the number of data points over the span of time that will be recorded.

Readings recorded will span at least X days

If you know how long you want to record, the Configuration screen will automatically set the number of readings to be collected at a particular interval. This setting will only have an effect if the above option "Record readings so that:" is selected.

Number of readings to record X maximum is Y

This data box will display the calculated number of readings if you select a time span and an interval. Alternatively, you can select the number of readings desired, and the time span will be altered based on the interval. If this is selected, the logger will stop logging when the number of readings has been gathered and stored in memory. "Y" represents the maximum number of readings the LogTag can store, however with a selected interval and a selected time span, you may not need to use all of the available data space. This setting will only have an effect if the above option "Record readings so that:" is selected.

Record a reading every X

This determines how frequently the LogTag records the environmental humidity and/or temperature into its internal memory.

Begin recording after a delay of X

Determines how long after the START MARK button on the LogTag has been pressed that it will actually begin to record the environment humidity and/or temperature. This feature is useful for example, when the LogTag could falsely trigger an alert because the environmental conditions it is being started in is quite different to the environmental conditions to be monitored. If pre-start logging is enabled, the LogTag will continue to record pre-start readings during this delay.

Enable the OK (Green) indicator

This determines whether or not the green light should function while the LogTag is recording after being started.

Humidity / Temperature These tab controls will allow the humidity and temperature alert

conditions to be configured independently. These tab controls will only appear when configuring a LogTag that has a humidity and a temperature sensor. If the LogTag has only one sensor then the following alert conditions will apply to that sensor.

Configure requires a password

This feature allows the user to define a password that must be

provided (see "Restricted Access Requirements" on page 28) to

configure the LogTag next time. If this option is enabled and the password changes, the user will be required to verify the new

password (see "Verify Access Password" on page 42) when the

wizard progresses to the next step. Passwords are case sensitive and therefore the passwords "Bob" and "bob", for example, are different.

Download requires a password

If this option is enabled, the LogTag's recorded data can only be downloaded after entering the correct password.

Note: Only one password can be provided for each LogTag. The same password applies to the Configure and Download actions.

Chapter 4 Preparing LogTag(s) for use 33

Upgrade logger to enable this feature

TRIX-8 and TREX-8 loggers which do not yet have the "Download requires a password" feature can be upgraded. These units will then require LogTag Analyzer revision 1.8r9 or later to be configured or downloaded, and an error message will be displayed in older versions.

If LogTag Analyzer configures such a logger, an additional check box is displayed:

The “Download requires a password” is grayed out if the update has not previously been applied to the logger being configured. Once you tick the “Update logger to enable this feature” box, the “Download requires a password” check box becomes available for activation. You can then select the password functions for either configuration or download. The logger will be permanently upgraded as soon as the configuration is downloaded.

Note:

 The update cannot be reversed.  If the “Update logger to enable this feature” is ticked, the

upgrade will perform, regardless whether any of the “...requires a password” tick boxes are enabled or not.

 If multiple units are configured at the same time using more

than one interface, all units will be upgraded if the Upgrade option is selected.

 When the “Again” button is used with a different unit, that unit

will also be upgraded.

Note: If a unit has been upgraded in a previous session, and is now configured using the “Download requires a password” function, units configured with the “Again” button in the same session will not automatically be upgraded; only those units that have already been upgraded separately in a previous session will have the “Password on download” function enabled.

If the battery within the LogTag is detected to be low and therefore not recommended for further use, the software will display a warning to you in the top right corner, like the following example.

Some LogTag models display the remaining percentage in this screen once it falls below half capacity. Some models cannot be configured any longer once their battery capacity falls below a pre-determined threshold.

34 LogTag Analyzer User Guide (2.0)

Alert Processing

The LogTag can display a visual alert if one or more of the configured alert conditions have been met. An alert condition can be a single alert reading (a reading outside of or including the upper and lower threshold values), a combination of consecutive alert readings or a total of alert readings encountered during the trip.

The threshold parameters are identified in LogTag Analyzer when the LogTag's readings are downloaded and displayed.

Please note that matching these to known conditions of interest in your monitoring program may require some information about the effects of exposure to different durations of out-of-range humidity and/or temperatures.

As with the other logging parameters these are adjusted in the "Configure LogTags for use" screen.

The following table describes each configurable option.

Function Purpose

Enable the Alert (Red) indicator when

This determines whether or not the red light should activate when an alert condition has been detected. An alert occurs when one or more of the conditions described below have been met. When an alert condition has occurred, this indicator will flash at a regular interval.

Chapter 4 Preparing LogTag(s) for use 35

Readings below X or above Y (inclusive)

You can set the upper threshold limit and lower threshold limit by entering the appropriate information in the boxes. If readings stay inside the range specified by X and Y the alert indicator will not activate. If a reading of X and below, or Y and above is recorded, the alert indicator may light up, dependent on the alert conditions. Charts will display alert readings according the settings made in the

Charts (on page 90) section of the 'Options' Screen.

Note: The values entered in these boxes are included in the alert range. In the above example 7 consecutive readings of 45°C will trigger an alert, whereas 7 consecutive readings of 44.9°C will not trigger an alert. Please set your alert values with this in mind.

After X consecutive alert readings (W minutes)

Tick this box, and enter a number into the adjacent field if you want to trigger an alert condition once X number of consecutive alert readings are recorded. Note that the number of minutes shown will depend on the number of alert readings you enter into the box AND the recording interval already specified. For example, if X is 3 and two readings are above the upper threshold limit but the subsequent reading is below the upper threshold limit and still above the lower threshold limit then the alert indicator will not activate. Maximum value is 256, minimum is 2.

After X alert readings have occurred (W minutes)

Tick this box, and enter a number into the adjacent field if you want to trigger an alert condition once a total number of alert readings have been recorded, regardless of whether they are consecutive or not. Maximum value is 256, minimum is 2.

You can increase or decrease the values with the arrows next to the fields. Please note these are linked and certain combinations may not be allowed.

Leave alert indicator enabled even if readings return within alert range

If this option is enabled then the alert indicator will remain active, even if the current reading does not meet the alert conditions specified by the previous controls.

If this option is disabled then the alert indicator will remain active only if the current reading meets the alert conditions specified by the previous controls.

Clear and reset alert when START MARK button pressed

If this feature is enabled, any user can turn off an active alert by pressing the LogTag's START MARK button. It will also reset the internal alert counters such that it would be as if no alert condition had occurred at all while the LogTag was recording.

Should the LogTag subsequently detect a further alert condition, the alert will activate again.

Once the LogTag has finished recording, pressing the START MARK button will not clear and reset any active alert.

If the LogTag being configured does not support this feature, it will be disabled and its setting cannot be changed.

36 LogTag Analyzer User Guide (2.0)

Example:

You wish to configured a LogTag so alert conditions are indicated if 5 continuous readings are out-of-range or 7 total readings are out-of-range. Alert parameters should be set as follows:

This table shows how different conditions would result in the Alert Indicator flashing or not:

What the LogTag recorded What the LogTag indicated

2 readings out-of-range, return to normal, 2 readings out-of-range, return to normal, 2 readings out-of-range, return to normal

Neither alert condition is met. The maximum number of consecutive out-of-spec readings is only 2 (5 required.) The total out-of-range events equals 2 + 2 + 2 = 6. The alert condition is 7 total, so the alert does not go off.

No Flashing Red Alert Indicator

4 readings out-of-range, return to normal, 4 readings out-of-range

The first alert condition is not met, as the the maximum number of consecutive alert condition readings is only 4 (5 required.) The second alert condition however IS met since the total alert condition readings equals 4 + 4 = 8. The alert condition is 7 total. so the alert DOES go off.

Flashing Red Alert Indicator

4 readings out-of-range, return to normal, 2 readings out-of-range

Neither alert condition is met. The maximum number of consecutive alert condition readings is only 4 (5 required.) The total number of alert condition readings equals 4 + 2 = 6. The alert condition is 7 total, so the alert does not go off.

No Flashing Red Alert Indicator

Chapter 4 Preparing LogTag(s) for use 37

6 readings out-of-range, return to normal The second alert condition is not met, as the

total out-of-range events equals 6 (7 required.) The maximum number of consecutive alert condition readings however is 6, the alert condition is 5 consecutive readings, so the alert DOES go off.

Flashing Red Alert Indicator

Please note following special conditions:

1. If you wish an alert to be indicated on the first reading that is recorded out-of-spec, place a tick in the box next to "Enable the Alert (Red) indicator when" and remove the ticks in both boxes next to the "After X consecutive alert readings" and "After X alert readings have occurred".

2. You can not enter a number into the "After X consecutive alert readings" field which is larger than the number in "After X alert readings have occurred", since the latter alert condition would always be met first.

3. Similarly, you can not enter a number into the "After X alert readings have occurred" field which is smaller than the number in "After X consecutive alert readings". The software will adjust field values as appropriate.

Advanced Alert Settings

Some LogTags support more detailed alert settings than described before. If LogTag Analyzer encounters one of these loggers, an additional

button is visible in

the bottom left of the configuration screen. When this button is pressed, the alert configuration screen changes and displays

additional settings:

The red alert indicator can now be configured independently for upper and lower alert values.

38 LogTag Analyzer User Guide (2.0)

Function

Purpose

Readings above X Readings below Y

(inclusive)

In addition to entering the threshold levels, tick the boxes next to "Readings above" or "Readings below" to enable the alert conditions for only the upper or only the lower threshold settings, or for both. If both boxes are ticked, the behaviour is the same as for the standard alert settings. The charts will display alert readings according to the settings made in the

Charts (on page 90) section of the 'Options' Screen.

After X consecutive alert readings (W minutes) Readings above Readings below

Tick the boxes next to "Readings above" or "Readings below" to establish whether only readings above and including the upper threshold or only readings below and including the lower threshold should count towards the consecutive alert readings. If both boxes are ticked, the behaviour is the same as for the standard alert settings. If the Alert Indicator is disabled for either the upper or the lower alert, the respective box for the consecutive alert is grayed out and cannot be ticked.

After X alert readings have occurred (W minutes) Readings above Readings below

Tick the boxes next to "Readings above" or "Readings below" to establish whether only readings above and including the upper threshold or only readings below and including the lower threshold should count towards the total number of alert readings. If both boxes are ticked, the behaviour is the same as for the standard alert settings. If the Alert Indicator is disabled for either the upper or the lower alert, the respective box for the alert total is grayed out and cannot be ticked.

The advanced settings are displayed automatically without the need to press if an advanced configuration is already found in the logger to be configured. If you do not

wish to use the advanced settings, press

, and the standard Alert Processing

(on page 34) configuration screen is displayed.

Example:

You wish to configure a LogTag so an alert is displayed if 5 continuous readings are out-of-range or 7 total readings are out-of-range, but only if the temperature goes to 20ºC and above. You wish to see in LogTag Analyzer if the product has gone to 0ºC and below, but you do not wish to trigger an alert for this condition. Alert parameters should be set as follows:

Chapter 4 Preparing LogTag(s) for use 39

This table shows how different conditions would result in the Alert Indicator flashing or not:

What the LogTag recorded What the LogTag indicated

2 readings of 20ºC or above, return to normal, 8 readings at 0ºC or below, return to normal, 4 readings of 20ºC or above, return to normal

Neither alert condition is met. The maximum number of consecutive out-of-spec readings is only 2 (5 required, the 8 readings below 0ºC do not count towards alert readings). The total out-of-range events equals 2 + 4 = 6. The alert condition is 7 total, so the alert does not go off, as again the 8 readings below 0ºC do not count towards alert readings.

No Flashing Red Alert Indicator

4 readings of 20ºC or above, return to normal, 4 readings of 20ºC or above

The first alert condition is not met, as the the maximum number of consecutive out-of-spec readings is only 4 (5 required.) The second alert condition however IS met since the total out-of-range events equals 4 + 4 = 8. The alert condition is 7 total. so the alert DOES go off.

Flashing Red Alert Indicator

Separate alert conditions are useful if you expect the monitored product to encounter temperatures lower than the lowest possible alert temperature. In this case a flashing alert indicator may not necessarily indicate an unfavourable condition was encountered. In programs where such conditions are monitored the lower alert should be turned off.

Display Logger Alarms

TRID30-7F and TRID30-7R loggers have a different settings screen.

The settings are similar to the Advanced Alert Settings on page 37, hence they are not explained again here. There is however one notable exception; for each range (above or below) you can only select either accumulative or consecutive readings, but not a combination of both. This does however give you the option to select e.g. a different number of cumulative readings for above and below ranges.

In this screen you can also see an

button. When clicking this button, following configuration screen is displayed, allowing you to enter parameters specific to TRID30-7F and TRID30-7R loggers.

Chapter 4 Preparing LogTag(s) for use 41

Function

Purpose

Clear and reset alarm when STOP/CLEAR button pressed

If this option is enabled, any user can turn off an active alarm by pressing the LogTag's STOP/CLEAR button. It will also reset the internal counters such that it would be as if no alarm had occurred while the LogTag was recording. Should the LogTag subsequently detect a further alarm condition, the alarm will activate again. Once the LogTag has finished recording, pressing the STOP/CLEAR button will not clear and reset any active alarm.

In any case, an alarm will be registered in the day summary, regardless whether it was cleared or not.

Alarm remains on even if readings return to non-violation range

If this option is enabled then the alarm symbol will stay on, even if the current reading does not meet the alarm conditions specified by the previous controls.

If this option is disabled then the alarm symbol will stay on only if the current reading meets the alarm conditions specified by the previous controls.

Pause alarm/statistics processing for X readings

If this option is enabled, pressing either button on the LogTag while recording excludes the next reading from the alarm and statistics calculations; PAUSED will now be shown on the display. This allows the user to review the statistics or clear an alarm without causing an invalid reading, alarm or statistic.

Switch off display after 30 seconds

If this option is enabled, the display will turn off after 30 seconds to save battery power.

Allow logging stop with STOP button

If this option is enabled, the LogTag can be stopped by pressing the STOP button. The recorder will no longer take any readings, however you can still review the day statistics and download the logged results to a PC with LogTag Analyzer.

Allow reset of logger with START button

If this option is enabled, TRID30-7F and TRID30-7R loggers can be re-activated and used again for a new trip by pressing the START button.

When re-activating the recorder, all previously recorded readings and statistics will be erased!

When this option is enabled, a warning box will be displayed to remind you this is enabled and can result in loss of data.

Show total summary days collected

If this option is enabled, the LogTag shows the number of days for which statistics have already been collected on the display.

Please refer to the LogTag TRID30-7F product specification & guide (http://www.logtagrecorders.com/products/pdf/LOGTAG_TRID30-7_PRODUCT_SPECIFIC ATION.pdf) for a detailed description on the functionality of these products.

42 LogTag Analyzer User Guide (2.0)

Verify Access Password

When configuring a LogTag for its next use, if the user enables the "Configure requires a

password on page 26" option and/or changes the password to restrict access to the

LogTag, then the user is required to verify the password to be defined before it will be stored in the LogTag. The window that will appear to verify the password will be similar to the following picture.

Once a password has been stored in the LogTag, further access to it can only be achieved by providing the correct password. Therefore, if a password is forgotten further access to the LogTag will not be possible. Passwords are case sensitive and therefore the passwords "Bob" and "bob", for example, are different.

Pre-start data collection

The LogTags support a feature called "pre-start logging", which can be selected during configuration.

When pre-start logging is enabled the LogTag will automatically start logging as soon as configuration is completed. It will record at the same sampling interval as defined in the configuration and will continue to record until the user starts the LogTag by pressing the START MARK button on the LogTag. Once the LogTag has been started, it will record as per the configuration settings. While the LogTag is recording pre-start readings the Alert LED on the LogTag will not activate if an alert condition is detected.

Pre-start logging is useful as a fail-safe recording setting so if the LogTag is not started at the appropriate time, the readings will still be available to view later.

When the readings are retrieved from the LogTag, any pre-start readings will be identified as pre-start readings so the user can quickly identify the readings recorded before and after the LogTag was started.

All LogTags have a finite amount of memory to store the readings it records. Therefore, while the LogTag is recording pre-start readings the LogTag will operate in its 'continuous

Chapter 4 Preparing LogTag(s) for use 43

operation' mode, which is explained further in the section "Continuous operation (on page

43)". Once the memory within the LogTag is full the oldest pre-start reading will be overwritten with the latest reading recorded, regardless of whether the reading recorded is a pre-start reading or a reading to be recorded after the LogTag has been started.

If a LogTag has been configured to start recording at a certain date/time, or for push button start from hibernation, no pre-start readings will be recorded.

Continuous operation

All LogTags have a finite amount of memory to store the readings that are recorded. When the LogTag is recording readings continuously it will not stop once the memory within the LogTag is full of readings. Rather it will replace the oldest reading stored within the LogTag with the latest reading so that only the most recent readings are maintained in the LogTag's memory.

If the LogTag being configured does not support this feature, you will not be able to select this setting.”

Working with batches of LogTags

You may find that at some stage you need perform a similar task on multiple LogTags, whether it is retrieving readings stored within the LogTags and/or preparing them for their next use. The LogTag Analyzer software has been designed to make the effort involved with multiple LogTags as simple as possible.

To retrieve a copy of the recorded readings stored within multiple LogTags, simply insert each LogTag to download into the Interface cradle. The software will then automatically retrieve the recorded data from the LogTag, save it to disk and then display the information for you. Therefore, you will be able to retrieve the recorded readings stored from within one or more LogTags without needing to interact with the software and/or computer.

To prepare multiple LogTags for use you can use the "Wizard..." or the "Configure..." wizard, available in the "LogTag" menu, depending on whether or not you want to retrieve and save a copy of any readings recorded within the LogTags you are about to use. Simply prepare the first LogTag(s) as per usual and at the conclusion of the last step remove the LogTag(s) from their Interface Cradle, place the next LogTag(s) to be

prepared for their next use into an Interface Cradle and click

. Therefore, you will be able to prepare multiple LogTags for use with minimal interaction with the software and/or computer.

44 LogTag Analyzer User Guide (2.0)

Getting the best from your LogTag

Many users of humidity and/or temperature loggers are used to attaching the logger to a hook or tie-wrapping them to a monitored object. A wide variety of attachment methods can be used with the hole on upper right hand corner of the LogTag, such as bolting the LogTag in position, attaching it to a packaging strap, using a car-seal for security or other means.

The hole is quite strong, so most means of attachment will not compromise the structural integrity of the LogTag. We do, however, recommend that the dead weight stress on the hole itself not exceed 5 pounds (2 Kg).

The sensor for the LogTag is also very responsive, so we recommend you position the LogTag in a location, where it will not be susceptible to changes in temperature due to operational activities. For example, it is not recommended you place a LogTag beside a door way, as every time someone passes through the door, the LogTag will register the change of environmental temperature due to the breeze that will be generated by the person, which does not necessarily reflect the overall temperature of the environment been monitored.

Chapter 4 Preparing LogTag(s) for use 45

Prolonging battery life

If your LogTag is not going to be used for extended periods of time, it may be worthwhile to set the LogTag into "Hibernation" mode. In "Hibernation" mode the LogTag will consume minimal power, which will extend the battery life when compared with leaving an idle LogTag in operating mode.

While a LogTag is in "Hibernation" mode it will:

1 Not be able to record and store any new readings. 2 Not activate the Alert and OK lights. 3 Not respond to the START MARK button being pressed

The only exception is when the LogTag has been configured for 'Push button start from hibernation' in the configuration screen. In this case pressing the START MARK button will 'wake' the product and commence logging according to the configured settings. Not every model supports this feature.

To 'wake' a LogTag from "Hibernation" mode to normal operating mode so that it can record and store new readings, go through the usual process of preparing it for next use (see "Preparing LogTag(s) for use" on page 26).

To set a LogTag to "Hibernation" mode, select the “Hibernate...” menu item in the “LogTag...” menu.

46 LogTag Analyzer User Guide (2.0)

The following example illustrates using the "Hibernation" feature.

In this screen you will see one of the following pictures next to each of the items in the list:

 (no picture) indicates the LogTag is still in the process of being set to "Hibernation"

mode.



The LogTag was successfully set to hibernation mode.



The software was unable to set the LogTag to hibernation mode.

Once a LogTag has been successfully set to "Hibernation" mode it should be removed from the Interface Cradle before pressing any other button. As soon as the software communicates with a LogTag in "Hibernation" mode, for example through automatic download, Hibernation, etc, it will be returned to normal operating mode.

The extent to which the Hibernation mode will prolong the battery life of a LogTag may vary between different models and versions of LogTag products. Some LogTag models may not support Hibernation.

The LogTag stores the recorded readings in its internal memory. Since the LogTag contains the recorded readings in its internal memory, you must use the LogTag Analyzer software to extract the information from the LogTag through the Interface Cradle and into a format that can be displayed to you in a meaningful way. It is usually very important that the information retrieved from a LogTag is retained. The software will automatically save the information retrieved from a LogTag to your disk drive so that you can view the information at a later date, a useful feature if you require traceability. This chapter explains how you can retrieve the recorded information stored within a LogTag and have the software display it to you on the screen in a meaningful way.

Getting results from LogTag

You can retrieve the recordings from LogTag(s) as many times as you require. The process of retrieving data stored within a LogTag does not erase it from the LogTag's memory. If the LogTag is currently recording while you retrieve the information, it will continue to record without interruption.

There are three ways to retrieve the recorded results from a LogTag. 1 While the LogTag Analyzer software is open (does not need to be the currently active

software), simply slot the LogTag into the Interface Cradle. If the automatic download feature is enabled, the software will automatically retrieve the recorded readings, save the information to your disk drive and display the information to you. While the software is automatically retrieving the readings you will see an animated picture appear, similar to the following picture.

2 Click the "Download..." menu item located in the LogTag menu.

This is the second quickest option, as it does not include the steps involved in preparing the LogTag(s) for the ir next use.

3 Click the LogTag icon (

) or the "Wizard..." menu item located in the LogTag menu.

This option will allow you to prepare the LogTag for its next use after retrieving the readings stored within the LogTag. If you do not need to configure the LogTag for its next use now, the previous option described may be preferred as it will not involve the configuration steps and therefore be a quicker and simpler method.

The wizard will appear once you have selected the appropriate option of your choice to guide you through the necessary steps to retrieve the recorded readings. While the wizard is visible the "Automatic download" feature will be temporarily disabled. You will not be able to access any of the Wizards while an "Automatic download" is in progress.

Every time you download a LogTag Recorder to your computer the data are automatically saved into a file with a *.ltd file extension (LogTag Data). This type of file is unique to LogTag data loggers and can only be read by LogTag Analyzer software.

You can:  generate a name for this file, which contains certain key details about the unit (File

Name on page 106)

 decide if existing files with older data should be overwritten or kept (Uniqueness on

page 108)

 automatically send files to e-mail recipients and FTP sites (Automation on page 92)  automatically export data to other file formats (Exports and Reports on page 109) and

save all or part of the data to make them accessible to other users (Selected LogTag

files on page 50 and PDF files on page 52).

Please refer to the respective sections in this user guide for more information.

Saving a Multi Chart file

If the main LogTag Analyzer window currently displays a Multi-Chart as explained in

Combining charts onto a single chart (on page 64), you can save the current configuration

by clicking on the

toolbar icon or selecting the "Save" command from the File menu (on page 119). Select a file name and location for your Multi Chart file. The file extension for Multi Chart files is "*.multi".

Note: The Multi Chart file should be saved in the same folder as the individual data files. If any of the data files referenced in a Multi Chart file are renamed, deleted, or moved to a different folder, the Multi Chart configuration cannot be displayed.

The configuration file contains information about the data files included in the Multi Chart display, the subtitle, chart colors, and time offset when Shifting chart start times (see "Combining charts onto a single chart" on page 64).

Any annotations added to the Multi chart display are saved in a separate annotation file with the file extension ".anno". This file must be located in the same folder as the Multi Chart file to be included in the Multi Chart display.

To open a previously saved Multi Chart configuration file, click on the

toolbar icon or select the "Open..." command from the File menu (on page 119), then select the "*.multi" file to be opened.

50 LogTag Analyzer User Guide (2.0)

To save a Multi Chart file under a different name, select the Save As... command from the File menu (on page 119) and enter a new file name.

Selected LogTag Data files (*.sltd)

Users can save a file, which when opened again, will only display a selected time window of the recorded data. The time window of this "Selected LogTag Data" file is defined through the zoom settings of the currently active tab, or can be entered in the dialog box displayed when the "Save as..." command from the File menu (on page 119) is chosen with 'Selected LogTag Data (*.sltd)' as the file type.

Select a file name and location for your file.

Chapter 5 Results from LogTag 51

The chart of this file, which contains pre-start readings, has been zoomed to show only a small proportion of the readings:

The window slider shows there are still readings earlier and later than the displayed data. When saved as a *.sltd file, it will be automatically re-opened and now only displays the

previously zoomed readings:

Note: Those readings which are no longer displayed are still present in the file. Any *.sltd file can be saved as a *.ltd file, and when re-opened, all readings taken by the recorder during this trip will become available for viewing.

This can also be achieved by simply re-naming the file from *.sltd to *.ltd.

Files with a *.sltd extension cannot be read by versions of LogTag Analyzer earlier than

2.0, they can however be read once renamed to *.ltd. *.sltd files can also be opened directly from e-mail attachments or by double clicking the

file in Windows Explorer, as the installer forLogTag Analyzer registers this file extension and associates it with LogTag Analyzer.

PDF files

LogTag Analyzer can save the currently active LogTag data window to a PDF file. One single file will be generated with chart images, a data listing and summary included for each tab.

PDF files can be generated automatically, or by selecting "Save as" from the File menu (on page 119). Select a file name and location for your PDF file. Automatic generation of PDF files is enabled in the section about Exports and Reports on page 109. Here you can also define the composition of the PDF file.

Click the

button; the following dialogue window is displayed, allowing

you to select which content of the PDF file will be created.

Note: Only one single Data listing will be created. Depending on which sections are enabled, pre-start only, chart only or all readings will be included.

Chapter 5 Results from LogTag 53

Each section can be identified by its heading. If a chart is zoomed, the PDF file will also contain a zoomed setting.

Understanding the results

The Data Screen is an all purpose data display. The window appears inside the main LogTag Analyzer window, and has a series of tabs along the bottom. Each of these tabs changes the Data Screen display.

The different display types are:

Chart A display of the data in a time versus humidity and/or temperature

chart.

54 LogTag Analyzer User Guide (2.0)

Data A listing (spreadsheet style) of the time versus humidity and/or

temperature data.

Summary A summary of the data, including averages, ranges, alert results,

LogTag identification data, and other information. Pre-Start Chart A chart of data stored by the LogTag prior to it being started. Pre-Start Data A listing of the data stored by the LogTag prior it being started. Pre-Start Summary A summary of the data stored by the LogTag prior to it being started. All Chart A chart of the all of the data stored in the LogTag including the data

prior to it being started and after being started. All Data A listing of the all of the data stored in the LogTag including the data

prior to it being started and after being started. All Summary A summary of all of the data stored in the LogTag including the data

prior to it being started and after being started. Day Summary A summary of the day statistics for display loggers.

The screens that are typically used are the first three (Chart, Data and Summary), since they represent the normal usage of the LogTag. The other Data Screens are included to deal with situations where the LogTag may have not been activated due to user error; the data is still collected and available. LogTags may be handled by those who are unfamiliar with the start feature. The “pre-start logging on page 42” feature protects against accidental “no starts” to preserve data that may be valuable.

In some cases, not all the "tabs" previously described will be displayed, for example you may only see Chart, Data and Summary. If the LogTag has been configured to not record any pre-start data, the downloaded data will not display any; you will only see the data that has been set up in the “configured mode” and recorded after starting the LogTag. Pre-start recording is an option, not a default. Also if the LogTag was configured to record continuously and the data has wrapped in memory all the pre-start data would have been replaced with more recent data and as such there will be no pre-start data left to display.

Inspecting the information at close range

When a file is displayed either from downloading or from calling up a stored data file, the file typically appears as a chart. It might look something like this:

The display does not show all of the available data points. For more detail, you can zoom in and display just one small section of the charted data. Using the mouse, find the upper left corner of a window of interest, hold down the left mouse button, and move the mouse to the bottom right corner. The zone of interest will be highlighted.

56 LogTag Analyzer User Guide (2.0)

The highlighted zone is immediately displayed after the left mouse button is released on the maximum displayable resolution:

This display now shows the maximum detail from the highlighted area. When this mouse operation has been completed, for example, a picture of the highlighted

area can be placed on the clipboard. This picture can be then be pasted into any Microsoft Windows

application. For example, if you are writing a letter and want to illustrate a point based on chart data from a LogTag, you can paste the picture of the chart directly into the letter.

When the mouse pointer is moved over the chart, a small window (tooltip) is displayed near the mouse pointer. It displays the reading closest to the mouse pointer position. If the readings are very close together, it is a good idea to zoom in to an area of interest to inspect individual readings with the help of tooltips.

The tooltip will always show date and time of the recording, even when elapsed time is chosen for the x-axis display. This will allow you to get the date and time information quickly without having to change the setting in the options for Charts (on page 90).

Chapter 5 Results from LogTag 57

Whenever the data displayed on the chart has been zoomed in to show more detail and is showing only a portion of the charted data, if you click on the corresponding Data tab you will see that only the readings shown on the chart are currently displayed. If you also click on the corresponding Summary tab you will see an additional section of statistics that have been calculated based on only the portion of readings currently being shown on the Chart screen. Following is an example of the additional section of statistics that will appear within the Summary Screen when a section of the readings within the Chart screen have been zoomed in.

If there are readings beyond the limits of the sensor within the time interval that is being displayed, the statistics for this interval will be displayed as "**".

The Zoom Out (

) command in the Edit menu (on page 122) or on the toolbar (see "Toolbar commands" on page 126) can be used to revert the display back to showing the range of data points that were showing prior to the new zoom section being selected.

58 LogTag Analyzer User Guide (2.0)

Inspection marks are recorded each time the START MARK button is pressed on the LogTag. Each inspection mark is numbered and can be identified by counting the number of marks on the Chart display. If you click on the corresponding Summary tab and scroll down in the data record you will see a summary of all the points that were recorded between each subsequent inspection mark. Following is a picture of a portion of a Summary Screen showing the relevant information for the sequence of data points between the inspection mark #2 and inspection mark #3.

Manual scaling of the chart

To change the temperature and humidity scale, or select a range of readings by time and date, select “Manual Scaling” from the chart popup context menu.

The following dialog will be displayed:

Chapter 5 Results from LogTag 59

Range of sensor The chart is zoomed to the minimum and maximum values for

each sensor.

Range of readings The chart is zoomed to the minimum and maximum reading

values.

Manual Scaling This option lets you specify the date/time range, temperature and

humidity ranges (if applicable) for the chart display. The dialog shows the current zoom settings.

Click

to apply your selected settings.

To return to the previous zoom level, use the Zoom Out (

) command in the Edit menu

(on page 122) or on the toolbar (see "Toolbar commands" on page 126). By default, each chart is initially displayed zoomed to the range of readings. This default

setting can be changed in the Options dialog (see chapter “Charts (on page 90)”).

Chart annotations

To include more information in your chart you can add chart annotations. These will be displayed and printed with your chart.

Click the right mouse button at the location where you want to add the annotation. Select "Add" from the Annotations popup context menu. Enter the annotation text and click

. The annotation will be displayed in the chart. When you zoom the chart

display, the annotation will be zoomed with the chart readings.

To edit an annotation, move the mouse pointer into the area of an existing annotation. Click the right mouse button and select "Edit" from the Annotations popup context menu.

Edit the text and click

to display the edited annotation.

To delete an annotation, move the mouse pointer into the area of an existing annotation. Click the right mouse button and select "Delete" from the Annotations popup context menu. The annotation will be deleted.

Chapter 5 Results from LogTag 61

To delete all annotations, select "Delete All" from the Annotations popup context menu.

Selecting the "Show" command from the Annotations popup context menu will show or hide all of the annotations on the chart.

To save the annotations, click the

toolbar button or select the "Save" command from the "File (see "File Menu" on page 119)" menu. The annotations will be saved in a file with the same name as the data file and the file extension ".anno".

When saving annotations in Multi Chart mode, the software will ask you to specify a file name for the Multi Chart configuration, if you are saving this configuration for the first time.

Chart subtitle

The chart subtitle is displayed and printed underneath the chart title. To edit the subtitle, right-click on the area above the chart and select "Edit Chart Subtitle"

from the popup context menu.

Chapter 5 Results from LogTag 63

Enter or modify the text, then click to display the edited subtitle. To remove the subtitle, delete the text in the Edit Chart Subtitle dialog and click

To save the chart subtitle click on the

toolbar icon or select the Save (see "File Menu"

on page 119) command from the File (see "File Menu" on page 119) menu. If the LogTag Analyzer application is in Single Chart mode, the subtitle (and annotations)

for the currently active chart will be saved in a file with the chart file name and the file extension .anno.

In Multi Chart mode, the subtitle is saved in the Multi Chart configuration file (file extension .multi). If you are saving the configuration for the first time, you will be asked to specify a file name for the Multi Chart configuration.

Combining charts onto a single chart

To overlay multiple charts in one view, select the Multi Chart ( ) command. All charts that are currently open will be displayed together. Additional files opened while in Multi Chart mode (including data downloaded from LogTags) will be added to the display.

Each of the individual charts will be displayed with a letter symbol to allow you to tell them apart. The legend contains an entry for each chart showing the chart name and the corresponding letter.

You can change the background color for the Multi Chart display through the Charts (on page 90) section in the Options (see "Customizing the software" on page 86) Window.

To remove charts from the Multi Chart display, use the Single Chart (

) command to

switch to Single Chart mode, then close the files you don't want to display. Select the Multi Chart (

) command to switch back to Multi Chart mode.

You will notice that the Data and Summary tabs are not available in the Multi Chart display. If you require additional information about the chart data, activate the display of

Chapter 5 Results from LogTag 65

the desired statistics on in the Chart Statistics (on page 89) section in the Options (see "Customizing the software" on page 86) Window. The chosen values will be displayed separately for each chart.

You can also view Min, Max and Average Charts (see "Special Chart Tabs" on page 68), and select other options.

Changing Chart Colours

By default, all charts in the Multi Chart display are displayed in the colors specified in the

Charts (on page 90) section within the Options (see "Customizing the software" on page

86) Window. To change the display color of individual charts/sensors, move the mouse pointer over a

chart until the tooltip is displayed. Right-click, then select "Change Chart Color" from the popup context menu.

Select the desired colors for the chart readings and markers in the color selector boxes. To restore the default color (as specified in the Charts (on page 90) section within the

Options (see "Customizing the software" on page 86) Window), select the "Restore

Defaults" command.

Shifting chart start times

For easier data comparison, chart start times can be shifted in Multi Chart display. There are two ways to shift a chart along the time axis:

66 LogTag Analyzer User Guide (2.0)

1. Move the mouse pointer over the chart until the appropriate tooltip is displayed. Right-click, then select the "Shift Chart" command from the popup context menu. This will cause the following dialog to be displayed, where the new start time and date can be entered, or the chart can be revert to its original date/time by selecting the "Original start time" button. Click the OK button to display the change.

2. Press and hold the CTRL key, left-click on the chart you would like to move, and drag the chart to new the position.

An additional time axis is displayed for each shifted chart indicating the corresponding time in relation to the original start time.

Note: Shifting a chart will not change any of the original recorded data, only the location the data is displayed in relation to other charts within the Multi Chart display will change.

Chapter 5 Results from LogTag 67

Aligning Charts

Select "Align Charts" from the popup context menu to automatically align all charts in the current Multi Chart window.

The charts are aligned to the earliest start time:

- "Chart" tab: All start times are aligned.

- "Pre-start Chart" tab: All charts with Pre-start readings are aligned to the earliest Pre-start reading.

- "All Chart" tab: Charts are aligned to the earliest reading (Pre-start reading if any Pre-start readings have been recorded for the chart).

Every chart is assigned a different colour and a time axis is displayed to illustrate the original start time. You can display the elapsed time instead of the date/time by selecting the "Elapsed Time" option in the Chart Options dialog (Charts (on page 90)).

Aligning charts in one tab will also influence how these charts are represented in the other tabs. If for example you select "Align Charts" in the "Chart" tab, and switch to the "All Chart" tab, you will notice that the charts are now aligned at a new origin, with all pre-start readings to the left and all readings to the right of this origin. The charts in the "Pre-start" tab are aligned with the last pre-start reading to the right.

To revert to the original start times for all charts, select

in the toolbar to switch to

Single Chart mode, then switch back to Multi Chart mode with

68 LogTag Analyzer User Guide (2.0)

Special Chart Tabs

When you select the average tab command in the toolbar, up to three additional chart tabs will be shown, with the Chart Average tab highlighted:

These chart tabs display graphs calculated from the "Chart", "Pre-Start Chart", and "All chart" tabs and show minimum, maximum and average value graphs. Changes in either of the three original data displays, such as adding a new file and aligning or shifting charts, result in a re-display of the corresponding "Min/Max/Average" tab, e.g. if one of the charts in the "Pre-Start Chart" is shifted, the "Pre-Start Min/Max/Average" chart would redraw showing graphs based on the updated values.

You can annotate these special chart tabs in the same way as other chart tabs; such annotations will be visible in the other chart tabs and are stored with the multi chart when saved.

Please note that following behaviour applies to these special chart tabs:

 Zoom settings will not be transferred to the "Average" tabs.  Download marks and inspection marks will not be displayed in the "Average" tabs.  Non-validated readings and re-calibrated readings will not be displayed with the

special attributes, even if set in the options. If you have chosen to "show non-validated readings", they are included in the minimum/maximum/average calculations, otherwise not.

 To avoid memory overflows there are some restrictions regarding the maximum

allowed time span of the charts in a multi-chart. These restrictions vary with logging interval, should you try to add a chart outside the allowed range following dialogue box will appear:

In this case the multi chart will disassemble, so you can close the window whose chart you no longer want to display, and re-assemble the multi-chart by clicking on

Chapter 5 Results from LogTag 69

 If one or more of the charts have sections with readings outside the LogTag's sensor

range, LogTag Analyzer is unable to calculate the minimum, maximum and average values, and those sections of the graph will not be displayed. This will likely result in a "broken" graph line, regardless of whether "show readings beyond specifications" in the Charts (on page 90) section in the Options (see "Customizing the software" on page 86) Window is enabled or not.

 Due to the large number of calculations performed in this feature, specifically when

opening large numbers of charts spanning long periods, having the average tabs displayed can occupy large amounts of memory and run slow. Therefore we recommend only turning the feature on when required.

Clicking on the highlighted average tab

command will turn the average tabs off.

Selecting the single charts

command in the toolbar while the average charts are active will disassemble the multi chart, and when switching back to multi chart the average tabs will be displayed again until turned off.

Behind The Scenes

To create some meaningful results, LogTag Analyzer uses a special trend line process to calculate the minimum, maximum and average values across multiple charts, rather than a histogram. It is important you understand this mechanism, so you can interpret the displayed readings correctly.

This is an example of two LogTags, one with a 5 minute log interval (A) and the other (B) logging every 2 minutes.

70 LogTag Analyzer User Guide (2.0)

Before the data are displayed in an average tab, LogTag Analyzer normalizes every chart's readings so they fall in line with the logging interval of the LogTag with the shortest log interval, in this case unit (B). It does not shift any charts, but rather calculates a theoretical value for those reading times by linear interpolation. Interpolation determines probable environmental conditions, i.e. what the LogTag would have recorded if taking a reading at that time.

Without this method, it would not be possible to compare LogTags with different log intervals, or units that have the same log interval, but were started at different times.

Starting with the earliest time present in the chart, a value is created for each LogTag as if it had recorded a log at that time. It is those values that are used to calculate and display the minimum, maximum and average charts.

As a result of this process, absolute values for minimum and maximum may not always be shown if they do not fall on normalized times, as seen in the example at 10:35 - despite 21ºC being the maximum it will not be displayed as it is not a normalized value.

Note: The charts in above example are based on LogTags started at the same time. If unit (A) had been started earlier, depending on the start time unit (B) may also have its readings interpolated. To ensure the chart with the shortest log interval always has its real values shown, please use the Aligning Charts (on page 67) function from the context menu.

Chapter 5 Results from LogTag 71

Automatically calculated statistics

When a file is displayed either from downloading or from calling up a stored data file, the software will automatically calculate and display some statistics of the recorded data. These statistics are shown on the corresponding Summary tab and are also calculated for each sequence of data points between the inspection marks.

If any readings within the time interval are beyond the limits of the sensor, the values for Average Reading, Standard Deviation, and Mean Kinetic Temperature will not displayed for the relevant time interval.

Average Reading

The Average Reading is the arithmetic mean of the sequence of data points. It is calculated by adding all the data point values together and then dividing the total by the number of data points. Mathematically this formula can expressed as illustrated in the following picture:

Where: av the calculated arithmetic mean n the number of data points to include in the calculation t

a data point to include in the calculation

For example, if there were 5 data points to calculate the arithmetic mean of and they were, 12.3, 15.9, 16.2, 14.7, 14.9, then the arithmetic mean would be 14.8.

72 LogTag Analyzer User Guide (2.0)

Standard Deviation

The standard deviation is a useful for determining how spread out the readings are from the arithmetic mean (Average Reading). Most controlled environments typically try to keep the environmental conditions at a stable and consistent humidity and/or temperature. The standard deviation can be used to help indicate how stable the environmental conditions were maintained. One standard deviation (sometimes expressed as "one sigma") away from the mean, positive or negative represents approximat ely 68 percent of all the readings. Two standard deviations, or two sigmas, away from the mean represents approximately 95 percent of the readings. Three standard deviations represent about 99 percent of the readings.

For example, if the arithmetic mean of the readings was 50.6°C and the standard deviation was 2.3°C, then approximately 68% of the readings were between 48.3°C and

52.9°C, 95% of all the readings were between 46.0°C and 55.2°C and 99% of the readings were between 43.7°C and 57.5°C. Further more, if all the readings were recorded over a span of 1 day (24 hours) then the temperature was between 48.3°C and

52.9°C for approximately 16 hours and 19 minutes during the recorded period of time. Mathematically the formula for calculating the standard deviation can expressed as

illustrated in the following picture:

Where: s the calculated standard deviation n the number of readings to include in the calculation av the calculated arithmetic mean t

a reading to include in the calculation

For example, if there were 5 readings to calculate the standard deviation of and they were, 12.3, 15.9, 16.2, 14.7, 14.9, then the standard deviation would be 1.54

Chapter 5 Results from LogTag 73

Mean Kinetic Temperature

Some products and materials have accelerated rates of degradation at higher temperatures. For example, perishable food items, pharmaceutical products and many forms of bacteria can grow/degrade exponentially as the environmental temperature increases. Mean kinetic temperature is a calculation that accommodates the non-linear thermal effect temperature can have on products. Mean kinetic temperature is represented as the equivalent temperature the product was thermally subjected to during the period of time the various temperature reading were recorded.

Mathematically the formula for calculating the mean kinetic temperature can expressed as illustrated in the following picture:

Where: mkt Mean kinetic temperature, in degrees Celsius

the activation energy. By default LogTag Analyzer uses an activation energy value of 83.144 KJ/mol for the calculation.

You can select a custom value for ΔH by clicking t he

button in the Summary Statistics or Chart

Statistics option screen and entering the desired value.

Charts and the Statistics page display the ΔH parameter if it is different to the default value:

R the universal gas constant, which is 0.0083144 KJ/mol K

74 LogTag Analyzer User Guide (2.0)

n the number of data points to include in the calculation t

a data point to include in the calculation, in degrees

Celsius

For example, if there were 5 data points to calculate the mean kinetic temperature of and they were, 12.3, 15.9, 16.2, 14.7 and 14.9 degrees Celsius, then the mean kinetic temperature would be 14.9 degrees Celsius using the default ΔH.

Chapter 5 Results from LogTag 75

Degree Minutes

There are some products and materials that exist which can change their characteristics and/or degrade if they experience temperatures which are not within ideal conditions for long enough. For example, some products may experience freezer burn if they experience an extremely cold condition or experience a colder than ideal temperature for long enough period of time. Other products for example, ice cream, change their characteristics if they experience temperatures which allow it to melt. The LogTag Analyzer will automatically display the results of two separate Degree Minutes calculations. The result of the first Degree Minutes calculation displayed will be based on the readings that were recorded below the ideal conditions and the result of the second Degree Minutes calculation displayed will be based on the readings that were recorded above the ideal conditions. The ideal conditions used in the calculation of the Degree Minutes formula are based on the upper and lower alert values that where configured when the LogTag was originally prepared for use.

Mathematically the formula for calculating the degree minutes above alert can be expressed as illustrated in the following picture:

Where: degmin Total Degree Minutes spent above/below the alert

threshold.

The temperature that was above/below the alert threshold. a The alert te mperat ure t hreshold. s The duration of time, in minutes, the temperature was

sustained.

For example, if there were 5 data points to calculate the degree minutes of and they were, 12.3, 15.9, 16.2, 14.7 and 14.9 degrees, each of these temperatures were recorded at 2 minute intervals and the high alert temperature threshold was 12.6 degrees, then the degree minutes temperature above the upper alert threshold would be 22.6 degree-minutes.

76 LogTag Analyzer User Guide (2.0)

Displaying statistics

The statistics displayed on the Summary tab can be configured in the Options dialog. Refer to the (see chapter "Summary Statistics (on page 88)"). By default, all statistics are displayed on the Summary tab.

Statistics can also be displayed on the chart, underneath the legend. See chapter "Chart

Statistics (on page 89)" for more information about configuring the chart statistics.

If there are readings beyond the limits of the sensor within the time interval being displayed, the statistics for the relevant interval will be displayed as "**".

Printing the results

Printing from LogTag Analyzer is slightly different to printing from other common Windows software, as the printer functions in terms of range of information to print rather than range of pages. This technique allows you to focus on what you want printed rather than the pages showing the information.

Chapter 5 Results from LogTag 77

You can choose to print all of the information, select a range of dates and times to print from or select a range of "inspection" marks. This could be a very important for transit monitoring since post trip and pre-event data are not significant to a discussion or dispute centering on a humidity and/or temperature maintenance issue.

The print window can be brought up by simply clicking once on the "Print" icon (

) located on the toolbar (see "Menus and Toolbars" on page 117) or by clicking the "Print..." menu item from within the File menu.

Sending a file by e-mail direct from Analyzer

You can send files of interest to another person, by e-mail, directly from the software without the need to exit to your e-mail software or to deal with file attachments.

While you have the file of interest open and being displayed on the screen, just click once on the "Send Mail" icon (

) located on the toolbar (see "Menus and Toolbars" on page

117) and your e-mail software will pop up with the file already inserted as an attachment.

78 LogTag Analyzer User Guide (2.0)

Type the desired e-mail address to send the file of interest to, add any message that you wish to include, and then click "Send". That is all.

Clicking the "Send..." menu item within the File menu will achieve the same results as clicking the "Send Mail" icon as previously described.

Note, the recipient of the file will also need to have a copy of the LogTag Analyzer software to open and view the file that you sent. LogTag Analyzer software is free and can be downloaded from the LogTag Recorders Internet site, www.logtagrecorders.com.

If you want to attach your data files in file formats other than the LogTag Analyzer format, specify the desired file formats in the Exports and Reports (on page 109) section in the Options (see "Customizing the software" on page 86) Window. The data files will automatically be attached to your e-mail(s) in the desired formats.

To send a Multi Chart configuration, the configuration must first be saved to disk (see chapter Saving a Multi Chart configuration). The "Send Mail" command will automatically attach the multi chart configuration file, the annotation file (if annotations have been added) and the relevant individual data files to your e-mail(s).

Note: You can automatically send e-mails and upload files to ftp sites using LogTag Analyzer's automated SMTP and FTP functionality. Please see Automatic Uploading to FTP

sites and automatic e-mailing on page 93 for further details.

Calling up previous results

The files that have most recently opened and displayed are listed towards the bottom of the "File (see "File Menu" on page 119)" menu. To open other files, click the "Open" icon

(

) located on the toolbar (see "Menus and Toolbars" on page 117), which will display the "Open" file dialog similar to the following picture and allows the user to locate and open one or more files of interest.

You can open files from all locations accessible by the Windows™ Operating System, including network and ftp locations. Please refer to your operating system's help for more information.

Clicking the "Open..." menu item within the File menu will achieve the same results as clicking the "Open" icon as previously described.

After the software has been installed for the first time, there are two recently opened files listed in the "File" menu, even though no files have been opened yet. These are sample files, which were installed along with the software so that users can see an example of information that can be retrieved from LogTags. These files are not required for the correct operation of the software and therefore may be deleted at any time.

80 LogTag Analyzer User Guide (2.0)

You can also open files directly from within Windows™ Explorer or from within your e-mail software by double clicking on the file or right clicking and selecting "open" from the context menu. When opening files fro m e-mail programs that store attachments in temporary folders such as MS Outlook, you may be asked to store the file in a new location when performing furt her actions such as selecting multi-charts or uploading to FTP sites.

If the software is unable to open the file, it will display an error similar to the following picture. Clicking on

will start the process of checking the Internet for an

updated copy of the software (see "Getting updated software" on page 138).

Support for digital signatures is primarily provided for compliance with the US FDA 21 CFR Part 11 regulation - Electronic records and electronic signatures. Various industries however, may find inclusion of digital signatures beneficial towards their quality control and assurance systems.

Digital signatures allow users to include their digital signature within a LogTag Analyzer file along with a meaning/reason for the inclusion of the digital signature. To add digital signatures to LogTag Analyzer files, the copy of the LogTag Analyzer software being used must be connected to the LogTag User Server software. For more information about how to get the software to connect to the LogTag User Server software see the "User Server (on page 114)" set of options settings and/or contact your local network administrator.

While the file that the digital signature is to be added to is open and currently selected, add a digital signature by clicking on the "Digital Signatures" icon (

) located on the

toolbar (see "Menus and Toolbars" on page 117), which will display the "File Properties"

dialog with the "Digital Signatures" tab already activated, similar to the following picture.

Then click

to begin the process of adding a digital signature to the file. If

is disabled, moving the mouse pointer over and leaving it still

for a short time will revel the reason why the button is disabled.

Once the "Add Digital Signature" dialog is visible, enter your LogTag Analyzer user password and the select the meaning for the digital signature that is being added.

Click

to permanently add the digital signature to the file or to not add the digital signature. Multiple digital signatures from the same and/or different users to LogTag Analyzer files may be added to a single file.

How secure is my data

All LogTag files are encrypted and contain checks to detect if the file has been tampered with since it was originally created. If the software detects that a file has been tampered with, even by only one character or has become corrupted and therefore the data within does not represent the data originally retrieved from the LogTag, the software will not open the file and display the information within.

An additional validation and security feature of the LogTag is that it will automatically insert error detection codes periodically during recordings, which are used to detect corruption or manipulation of data. Whenever these detection codes for a block of recordings fails its integrity validation test, the relevant readings become marked as non validated readings. Non validated readings are displayed differently to validated readings to indicate that they have failed their integrity test.

Non validated recordings typically occur in the scenarios following scenarios: 1 One or more readings within the non validated block of readings is not the genuine

recorded value.

2 The LogTag has been configured to perform continuous recordings and once the

memory within the LogTag has been fully used, will cause older recordings to be overwritten, which will thereby invalidate the error detection code and integrity check for the block of readings the older recordings been overwritten exist within. In this scenario, it is not a problem that these recordings are non validated, rather it means

Chapter 5 Results from LogTag 83

that the particular block of recordings has only the validation and integrity protection offered by the communications between the LogTag and the computer system, which is typically the same, if not better than the level of protection offered by every other brand of logger available in the global market, that LogTag Recorders know of.

3 A communications or hardware failure has occurred during the transfer of the data

from the LogTag to the computer. In this scenario the problem is typically resolved by trying to retrieve the recordings from the LogTag again, while ensuring the contacts on the back of the LogTag are clean, that the contacts within the Interface Cradle are clean and that the contacts within the Interface Cradle are returning evenly to their normal position when the LogTag is removed.

Since the software does not modify any of the recorded data within a LogTag file at any time, if the software can open the file, regardless of how long ago it was created, the contents of the file will still represent the original recorded information retrieved from the LogTag.

Therefore, the files created by the LogTag Analyzer software meet all criteria for data integrity and data security as set forth in the US FDA 21 CFR Part 11 regulations. The firmware code that is embedded in the processor chip of each LogTag cannot be extracted or reverse-assembled. Accordingly, data sets that are recorded on the memory within the LogTag cannot be downloaded or modified except by being transferred to a LogTag file. There is no way to interfere with the process of the transfer of information between the LogTag and the software in such a way that data integrity would be compromised.

Viewing file properties

The file properties, which is accessed through the File Menu (on page 119) and/or through the

toolbar command, provides users with a brief summary about the data

included within the file, as indicated in the following picture.

Chapter 5 Results from LogTag 85

This file properties information is also available for viewing directly through the Windows Explorer software that was included with the Windows operating system, without the need to have the LogTag Analyzer software open. To view the information, simply locate the file of interest with Windows Explorer and, using the mouse, click the right button over the file and select the "Properties" menu item, with the left mouse button, from the menu that will be displayed, similar to the following picture.

Select the "Summary" tab and you will see the summary of the data contained in the file. If the contents of the file require a newer version of software to open and view, have become corrupted or have been modified then the "Summary" tab will not be visible.

If the LogTag has a limited number of trips left, this is also indicated here.

In the "Edit" menu is a command called "Options...".

This menu command opens a Window, which will allow the many of the features that the software offers to be customized. The following sections will provide an explanation of each of these options so that users will be able to make the best use of the software.

General Settings

The General Settings options allow you to change various preferences that will effect the overall appearance of the information shown by the software.

Show temperatures in

This will determine what units of measurement temperatures will be displayed in. The options include:

 Fahrenheit (°F)  Celsius (°C)  Kelvin (K)

Use Font

Determines what font to use to display and print information about LogTag recordings and is changed through the

button. A sample of the font selected will be shown

to you on the screen.

Language

This instructs the software which language for the software to use for all the information it displays and prints.

Summary Statistics

This option allows you to specify which statistics are displayed in the Summary tab. The statistics can be enabled or disabled by clicking the tick box for the relevant item in the list.

Chapter 6 Customizing the software 89

Chart Statistics

This option allows you to specify which statistics are displayed on the charts. The statistics can be enabled or disabled by clicking the tick box for the relevant item in the list.

Charts

The Charts options allow the various aspects of the charts that display the readings recorded by LogTags to be customized. At the base of the Window is a color selector and other relevant controls, which apply to the highlighted item on the list in the window.

Some experimentation with these settings will show very quickly how they work. Select a color in the color panel, click

, and then go to the Data screen to see the

results of the change. Note that the three regions on the chart display can be controlled. LogTags can be

configured to detect over and under conditions based on a series of temperature and/or humidity measurements. When the data is displayed graphically on the chart, these become color background regions. These are different colors for "at or above high alert limit", "between high alert limit and low alert limit" and "at or below low alert limit". This allows out-of-range and in-range data to be spotted easily on the listed or charted data.

By selecting a line style for the "above high alert limit" and "below low alert limit" regions you can improve the readability of the charts on black and white printouts.

You can choose to include or exclude non-validated data from the chart display by checking or un-checking the "Non-validated readings" check box in the list. If non-validated data is to be displayed, it can either appear just like validated data, or you can define a different colour and marker style to be used. Check the check box "Display non-validated readings differently:" to display non-validated data in the selected colour/style.

Chapter 6 Customizing the software 91

Please refer to section How secure is my data (on page 82) for a detailed explanation of non-validated data.

When readings beyond the specified measurement range of a LogTag have been recorded, the display will indicate this using the following techniques:

 The Chart display will not plot the out of range values and the chart curve will appear

with broken lines.

 The Data display will include "<" or ">" for each reading that is beyond the

specification range.

 The Statistics display will include "**" for each statistic that includes readings that are

beyond the specification range.

If the option "Show readings beyond specification" is enabled, all reading values will be displayed, even if the recorded readings are beyond the operating range of the LogTag.

For example, the TRIX-8 has a published minimum temperature of -40°C. Temperatures to -41.5°C may be displayed if the “Show readings beyond specification” is enabled, however the accuracy of recordings between -40 and -41.5 is unknown. Temperatures between -40 and -41.5 will be displayed even if the temperature falls to a much lower actual value.

LogTag Recorders provides no guarantee of temperature reading reliability or accuracy beyond the published range for a given product and the "Show readings beyond specification" option is not recommended to be enabled for general use.

The "Elapsed Time" option switches the x-Axis display between date/time and elapsed time since the beginning of the display period.

"Show Min/Max/Average Tab" shows up to three additional tabs in a multi chart with graphs representing Minimum, Maximum and Average readings (See Combining Charts

into a single chart on page 64.)

Most of the Chart Options settings can be enabled or disabled by clicking the tick box for the relevant item in the list.

Automation

The Automation options determine what the software does automatically when it detects a LogTag in the Interface Cradle.

Enable automatic download of readings from LogTags

Instructs the software to automatically retrieve recordings from a LogTag when it is placed in an Interface Cradle that is connected to the computer. While the software is automatically retrieving recordings from a LogTag an animated picture will appear on the screen to let the user know this action is being performed. With this function enabled, it is not necessary to go through the download wizard procedure. This function is very useful when working with multiple LogTags.

This function can be temporarily disabled by holding down the "Ctrl" key on the keyboard while a LogTag is placed in the Interface Cradle.

Display readings after successful download

Instructs the software to display the recordings after downloading them from the LogTag. The default display format is determined by the "Display" setting in the "File Settings (see "File and Folder Settings" on page 105)" option. This option will affect readings downloaded through the automatic download feature and when downloading through the Wizard approach.

Chapter 6 Customizing the software 93

Only show the latest set of readings after download

Instructs the software to only display the most recently retrieved set of readings on the screen. If there are multiple windows of readings open and being displayed, all of these windows will therefore be automatically closed and only the most recently retrieved set of readings will be displayed.

Automatic e-mailing and uploading to FTP sites

In the same way that LogTag Analyzer files are saved to a local hard drive, they can be automatically uploaded to an FTP site and automatically be e-mailed every time data from a LogTag are downloaded.

FTP (File Transfer Protocol) is a standard which describes how files are transferred between different computers and networks. SMTP (Simple Mail Transfer Protocol) is used for e-mail and describes how electronic mail is distributed across networks. Detailed explanations of how both FTP and SMTP work are beyond the scope of this manual, however if you wish to learn more about FTP, SMTP, e-mail and networking please refer to one of the many good articles available on the Internet, such as the ones on Wikipedia or the various FTP and SMTP client providers.

In the Automation dialogue you can select for both FTP and e-mail whether you wish to make the process automatic, on request, or both. If you activate manual uploading/e-mailing, but not automatic uploading/e-mailing, you need to press a button on the toolbar to upload or send the file in the currently active window. This button is in the form of a globe symbol, which also indicates which setting is currently active.

If the globe is active, and a small "F" is depicted in the lower right corner,

automatic FTP uploading is activated.

If the globe is active, and a small "e" is depicted in the upper right corner,

automatic e-mailing is activated.

If the globe is active, and both the "F" and the "e" are depicted, both automatic

FTP uploading and e-mailing are activated.

94 LogTag Analyzer User Guide (2.0)

If the globe is active, but no letter is displayed, neither automatic FTP uploading

nor automatic e-mailing are activated. Manual FTP or e-mail functions may still both be active.

If the globe is grayed out, neither automatic nor manual FTP or e-mail functions

are available.

When neither box for e-mailing has a tick, no e-mailing will be possible. Similarly, when neither box for FTP upload has a tick, no uploading via FTP will be possible, however in both cases the settings data will still remain stored.

Clicking on the FTP or E-mail settings buttons brings up the dialogue windows for the

Basic FTP settings (on page 100) or the Basic SMTP and e-mail settings (on page 95).

Usually this information will be provided by your network administrator. If your company has specific IT policies you may not be allowed to configure the settings yourself. In this case, or if your network administrator has already created a company wide access for multiple users, you may be provided with a settings file called "UploadSettings.dat". Your network administrator will detail instructions how to import these settings into LogTag Analyzer.

Changing FTP or e-mail settings while files are being uploaded will display following dialogue box when clicking OK to close the Options window.

Click "yes" to cancel the current upload, and "No" to continue uploading to the previously selected location.

When uploading or e-mailing files a status window is displayed at the bottom of the LogTag Analyzer window.

Chapter 6 Customizing the software 95

This window shows status messages related to the FTP and e-mailing functions. The window can be hidden by right clicking anywhere in it and de-selecting the Upload/Send Status box. It can be re-displayed by right clicking anywhere on the menu or toolbar and selecting the Upload/Send Status box.

Note: The manual e-mail function described here is different from the "send mail" button on the toolbar. The "send mail" button invokes your standard e-mail program, attaches the data file, requires you to fill in an e-mail address and press the send button. The manual e-mail function via SMTP does not use your standard e-mail program, but the configured SMTP settings and requires no further action once the globe button on the toolbar is pressed.

Note: Automatic upload via FTP and automatic e-mailing only work if a file is created by downloading data from a LogTag in the interface. If the uniqueness settings in the "File and Folder Settings" are set so that certain conditions do not result in creation of a new file, no file is uploaded or e-mailed either.

Files with formats other than the native LogTag Analyzer format can also be e-mailed or uploaded. They can be selected separately for each transfer mechanism in the respective "Settings" dialogue and are independent of the settings in the Exports and Reports (on page 109) option dialogue.

Note: If you upload a file via the manual or automatic FTP function, any file that already exists on the server with the same name will be overwritten. It is up to you to make sure files are created with unique file names.

Basic SMTP and e-mail settings

Disclaimer The distribution of unsolicited e-mails provides huge inconvenience to anyone with an

e-mail account. LogTag Analyzer's e-mail function allows the automated e-mailing of files to a large number of recipients simultaneously without user interaction. Some countries consider this as spam and will prosecute offenders.

It is therefore of the utmost importance that you as the sender obtain permission from the recipients to send these files. LogTag Recorders provides this functionality as a feature assisting in the distribution of information between various users within an organization and will not assume responsibility for any misuse of its software.

Setting up automated e-mailing requires two main pieces of information:

 The name of the SMTP server which you wish to use to send the e-mails and  A valid user name and password for the SMTP server.

96 LogTag Analyzer User Guide (2.0)

Once you click on the "SMTP Settings" button a dialogue window will appear, allowing you to enter the configuration data for the SMTP e-mail function. A lot of these settings will be familiar to you from your standard e-mail program.

If you have been supplied with access data by your network administrator we suggest you print the following table, enter the data into the fields provided and keep it in a safe place.

Field What to enter Your details

SMTP Server Enter the name of the SMTP server you

were given by your network administrator

SSL SSL stands for Secure Sockets Layer. You

may be required to tick this box if your SMTP server requires a secure connection. Typically this setting is not required, and your network administrator will set this up if required.

Chapter 6 Customizing the software 97

Use name and password

Some SMTP servers require an authentication method, especially if the SMTP server you are using is not provided by your ISP, e.g. if you are using e-mail accounts from a hosted site. In this case you need to tick this box and provide login data for this SMTP server. Quite often, though, you will not be required to use Authentication.

User Name Enter the user name you have been

allocated by your network administrator required for Authentication. Please note that for authentication this often needs to include a full e-mail address rather than just the SMTP login.

Password Enter the password you have been given

by your network administrator required for Authentication.

Name Enter the name as it should appear in the

recipients e-mail program. This can be your name or someone else's name.

E-mail address Enter the e-mail address that the recipient

can reply to by pressing the reply button of his e-mail program. This can be your e-mail address, or someone else's address.

Recipients Enter the e-mail addresses of the intended

recipients. Pressing the "add" button will bring up a new entry window where you can enter a recipient's name and e-mail address.

You can also highlight a recipient's name and edit the data or remove it from the list.

Subject Line Text entered in this line will be displayed in

the subject line of the e-mail when displayed on the recipients' e-mail

programs. Clicking on the

button will allow you to specify some file related information which will be entered into the subject line at the time of sending. You can enter your own text with the file related information.

98 LogTag Analyzer User Guide (2.0)

Advanced settings Press this button to display a new dialogue

window where you can enter advanced SMTP settings like port numbers, retries and log files. Refer to the section about

Advanced SMTP settings (on page 99).

Attach file in the following formats

Select all files that you wish to attach when the e-mail is sent. Each file ticked here will be created, regardless of the settings made in "EDIT - OPTIONS - EXPORTS AND REPORTS".

As a minimum you only need to provide an SMTP server address and one recipient e-mail address for this function to work.

Every time you make changes to these settings you should perform a test by pressing the "Send Test e-mail" button. LogTag Analyzer will

 check you have provided valid connection data,  send a test e-mail to the e-mail addresses in the recipient list.

If any of these actions fail, LogTag Analyzer will display one of the following error messages:

In this case the SMTP server requires authentication, and the data provided were not correct. Please enter the correct authentication data.

Chapter 6 Customizing the software 99

This error message is displayed if LogTag Analyzer could not connect to the specified SMTP site because it could not find it. This could be due to internet connectivity issues, due to an incorrect port name or due to a mis-spelt server name.

This error message is displayed if one or more of the addresses in the recipient list have an incorrect mail format (i.e. are not in the format a@b.c). LogTag Analyzer can only check for the correct format of the addresses, but not for correctness of the e-mail addresses. Please note if you do not provide a correct return address, you may not know that intended recipients are not receiving the messages.

We recommended you add your own e-mail address to the list of recipients. This way you get feedback if your e-mail has been sent correctly in your e-mail program. It is also good practice to enter a valid and correct e-mail return address for yourself. Some ISP's will not relay messages without a sender's address.

Advanced SMTP settings

Clicking on the "Advanced Settings" button in the SMTP settings dialogue displays following Window:

100 LogTag Analyzer User Guide (2.0)

This will allow experienced users to change additional settings normally associated with FTP transfers.

Field What to enter

Port Number The default port for providing SMTP connections is 25. Some

network administrators change the port number on their SMTP servers to increase security and stop hacking attacks. If your network administrator has advised a different port for connection, please enter it here.

In this case you may also need to change the settings of your firewall.

If you wish to learn more about this topic please see any of the published articles on networking and TCP/IP available on the Internet.

Retry If a connection cannot be established, LogTag Analyzer will retry to

e-mail the file again after the number of minutes entered here. This helps eliminate e-mail errors due to intermittent Internet connection errors.

Maximum Retries Enter the number of times LogTag Analyzer should tr y to e-mail the

file if previous attempts have not been successful.

Automatic Disconnect if idle

LogTag Analyzer will keep the connection to the SMTP server active, even if currently no files are being e-mailed. This avoids having to exchange password and login information every time a file is uploaded therefore providing faster uploads, especially if only a slow Internet connection is available. After a certain amount of inactivity the connection is dropped to save resources. Enter the time after which you wish LogTag Analyzer to automatically disconnect from the SMTP server.

Log uploads If a tick is placed in the box next to "Log uploads" the message

exchange between the SMTP server and LogTag Analyzer is recorded into a file. These files are automatically named "YYYY_M_D_LogTag Analyzer_SMTP.log", you can specify a

location where the files are created, or click

to browse to a

location of your choice.

Log Connection errors Tick this box if you wish connection errors to be logged. This is

recommended if you frequently experience upload errors and you wish to discuss this issue with your network administrator.

Click OK to store the settings or cancel to abort.

Basic FTP settings

You will require two main pieces of information to upload data to an FTP site:  The name of the FTP site and a directory on the site in which the files will be stored

once uploaded and

 A valid user name and password allowing you access to this directory.
