Overview

Overview
Vaisala Veriteq vLog 4.5 software provides high-integrity recordings of temperature, humidity and other conditions. It can also provide you with the level of file security required by the pharmaceutical industry, depending on the security key you use to install vLog. Your security key provides you with access to either vLog SP features or additional vLog VL features.
With Vaisala Veriteq vLog 4.5 you can:
• Create electronic records of temperature, humidity and

vLog SP or vLog VL?

While the core vLog features are the same, additional features are available if you install vLog using a vLog VL security key:
• Compatible with both Vaisala Veriteq SP- and VL-Series Data Loggers.
• Create secure graph and logger files - the security status of your data is identified on every report. You know whether files are secure or not, and if files have security problems or tampering issues.
• Data and user security - vLog uses Windows password authentication—domain level or local account authentication. Your IT staff can implement what they already use to protect other company assets.
• Audit Trail - A built-in audit trail report generator creates reports for all logger data or for a time period you specify. No changes to the system go unrecorded.
• Batch Setup and Transfer - Save time using the settings from one logger in additional loggers—start and stop time, sample interval, logger and channel descriptions, and channel flags. You can also configure the Batch Setup feature to support a range of COM ports.

Preparing to use Vaisala Veriteq vLog Software

Vaisala Veriteq vLog software supports one or more Vaisala Veriteq SP-Series Data Loggers, a Vaisala Veriteq cable (PC­IC cable if connecting by Serial port, INT-USB-DL cable if connecting by USB, or Digi and Ethernet cables if connecting via Digi or Vaisala Veriteq vNet device through the network), and a PC with an attached printer.
Vaisala Veriteq vLog 4.5 3
Overview
If you use vLog VL, you can also use Vaisala Veriteq VL­Series Validatable Data Loggers.
Once you connect loggers to a PC, you can use vLog software to configure logger settings such as the sampling interval, then place the loggers in the area where you want to measure conditions and record data. Your loggers collect the information and store it in their internal memory. Once the desired information is collected, you transfer it to a PC running vLog and import (“insert”) the data into a vLog graph. Use the graph to display, analyze, and print graphical or tabular reports, and, if needed, export the information to use in an analysis or presentation application.
VL-Series Validatable Data Loggers
Each Vaisala Veriteq VL-Series Validatable Data Logger is factory-calibrated against National Institute of Standards and Technology (NIST) traceable standards. All calibration information is stored digitally in the logger’s memory. For logger specifications, see www.vaisala.com/lifescience­hitech or contact Vaisala Canada Inc.
There are many models of VL-Series loggers to choose from, including the VL-1000, VL-1200, VL-1400, VL-1700, VL­2000, VL-4000 and VLT series. Each logger has one or more channels and can monitor and record data for FDA-regulated applications, including ambient temperature and relative humidity. Many loggers can also have optional plug-in external probes attached.

2 - Menu bar Allows access to the various software functions
3 - Toolbar Allows quick access to the most used software functions
4 - File security status
Vaisala Veriteq vLog 4.5 5
vLog VL: Shows the security level of the Graph file (note: If the check­sum in a logger file or graph file is invalid, vLog will not open the file). Tampered means at least one logger is a VL-Series logger but one of the loggers has an invalid checksum. Secure means each logger is a VL-Series logger and all data and graphs have valid checksums. Not Secure means there are security problems, such as one SP­Series logger shown in the graph, or one of the graphs or logger files does not have a checksum.

Setting Up and Using vLog— Overview

Ensuring Loggers are Calibrated

Vaisala Veriteq loggers are calibrated at Vaisala Canada Inc and should be calibrated on a suitable frequency as determined by the accuracy requirements of the application in which the product is used.
If you use vLog VL, the Calibration frequency should be specified when the loggers are purchased, and the next calibration date pre-set in the logger. Vaisala Canada Inc recommends a 90-day interval for the most critical applications, while a one-year interval may be adequate for less demanding situations.
To calibrate your loggers, contact Vaisala Canada Inc for pricing, lead times, and delivery arrangements.
Note: Treat the calibration process very carefully. The
consequences of poor calibration can be very expensive. Vaisala Veriteq loggers are high­accuracy instruments. In order to maintain the specified accuracy, it is essential to have trained calibration personnel, strict calibration proce­dures and proper test and calibration facilities. If you have questions about the calibration pro­cess, contact veriteqsupport@vaisala.com.

Validating Loggers (vLog VL)

For companies that are required to validate the vLog system (including VL-Series Validatable Data Loggers and vLog VL software) prior to use, Vaisala Canada Inc provides a comprehensive protocol document.
Each package includes installation qualification (IQ) and operational qualification (OQ) procedures, and forms. The information and forms are provided as hard copies in a 3-ring binder and in electronic form (Microsoft Word documents) on a CD-ROM. The electronic files provide an easy way for you to customize the forms for the application.

Linking Loggers to an Audit Trail File (vLog VL)

If you use vLog VL and have enabled security, it is very important to link loggers to a specific audit trail file so you can see the exact configuration changes that have occurred over time. This linkage only needs to be done once per logger. You will know a logger is not linked to an audit trail when you open the Logger Setup window and see the alert, “Logger is not linked to audit trail.”
To link a logger to an audit trail file: 1 From Logger | Setup, click the Setup button in the row for
Audit Trail Link.
2 You are prompted to link this logger to the audit trail file.
Click
Yes .
Now that the logger is linked to an audit trail file, changes made to the logger settings are tracked in the audit trail. To make changes to a logger linked to an audit trail, a user must first log on to a computer connected to the same audit trail.

Setting Logger Sample Timing

There are four main steps in setting the Logger Sample Timing:
a Set the Clear Mode.
b Set the Start Mode (see page 34).
c Set the Stop Mode (see page 35).
d Set the Sample Interval (see page 37).
Setting the Clear Mode
To configure the Clear mode:
Select Logger | Sample Timing.
1
2 Under Clear Mode, select one of the following options:
Do not clear logger - This is the default setting if the
logger memory is not yet full. Use this setting when the logger memory is not yet full and all you want to do is change Stop mode settings without clearing the existing samples. If the logger memory is full, or if Start mode or Sample Interval changes are required, you
Vaisala Veriteq vLog 4.5 33
Configuring Loggers
must use the Clear Logger setting to make the necessary changes.
Clear Logger - This is the default setting if the logger
memory is full. The Clear Logger setting allows you to modify both Start and Stop mode parameters and change Sample Interval values. Choosing this setting results in the logger’s memory being cleared following completion of the setup changes. You will lose data unless you transfer it first. If you are in doubt as to whether the information on the logger is still valuable, first make a copy of the data using
Logger | Transfer,
and then make the necessary logger setup changes.
When you choose
Clear logger, the Start Mode and Stop Mode
radio buttons become available.
Setting the Start Mode
The Start Mode enables you to choose when the logger starts taking samples.
To set the Start Mode:
Under Clear Mode, select the Clear logger option.

Under Start Mode, select one of the following options:
Start now - This option sets a connected logger to start
taking samples immediately (within one sample interval) after the changes in the Logger Sample Timing window have been applied to the logger’s memory.
Start at specified time - This option sets a connected
logger to start taking samples at a pre-defined date and time in the future. Until then, the logger remains dormant. This delayed start feature helps to save logger memory and minimizes the collection of unwanted data. You can also use the
Start Time option
to ensure that multiple loggers are synchronized to start logging at the same time.
3 When you choose the Start at specified time option, the
Start Time section of the Logger Sample Timing window
becomes available. Use the drop-down lists and
AM/PM radio buttons to set the time

you want the logger to begin recording samples.
Note: You cannot choose a date or time earlier than

Setting the Stop Mode
The Stop Mode enables you to choose how the connected logger operates once the memory is full, or when a specified time is reached.
To set the Stop Mode:
Under Stop Mode, select one of the following options:
Vaisala Veriteq vLog 4.5 35
Configuring Loggers
Wrap when full - This is the default method of collecting samples on the logger. When you choose this setting, samples are recorded in a first in, first out manner. When the memory is full, the logger continues to take samples by discarding the oldest one, and replacing it with the newest one. This setting ensures that you always have the latest data when you transfer from the logger. The length of time that the memory fills and wraps around is a function of the
Sample Interval (see
“Setting the Sample Interval” on page 37) you have set on the logger. vLog automatically calculates this time and displays it in the
Log Time section of the Logger
Sample Timing window.
Note: If the memory wraps around too quickly, you can
choose a longer sample interval.
Stop when full - When you choose this method, the logger stops taking readings once the memory is full. This option allows the maximum amount of samples to be taken without overwriting data. It is particularly important in any application where there is an
36

excessive time delay between the gathering of the data and the transferring of that data to the PC.
Stop at specified time - This method enables you to set
a precise time for a logger to stop recording data. When you choose this setting, both the
Time
sections of the Logger Sample Timing window are
Log Time and Stop
available.
The
Log Time drop-down lists enable you to set an elapsed
time for the logger to collect samples. For example, you can set the logger to collect samples for 24 hours, 48 hours, 7 days, and so on.
The
Stop Time drop-down lists enable you to set absolute
date and time values for when the logger is to stop taking samples.
Note: The Log Time and Stop Time options are interre-
lated. Setting the Log Time to a specified period automatically adjusts the Stop Time values. Adjusting the Stop Time Date and Time values, in turn, automatically adjusts the Log Time val­ues.

Setting the Sample Interval

You can change the sample interval on the logger to suit the requirements of the application. You can also set up more frequent sampling intervals to capture rapidly changing data, or spread out the readings to conserve memory usage and cover extended monitoring periods.
Note: You can only change sample intervals if you set
the Clear Mode to the Clear logger setting (“Set­ting the Clear Mode” on page 33).

2 Under Sample Interval, use the drop-down lists to set the
Days, Hours, Minutes, and Seconds to the desired sample
interval. If you want to use a sample interval of once per minute, click
Default. You can choose intervals ranging
from a minimum of ten seconds to once every 24 hours (with the exception of the VL-1000-VLT, VL-1200 and models SP-1016, SP-1200, SP-1416, VL-1016, VL-1416, which have minimum sample intervals of one minute). The total period covered by a logger before the memory is full depends on how many channels are enabled and the sample interval setting. This information is automatically calculated in the
Log Time section of the
Logger Sample Timing window.
Note: Running the logger with a sample interval
shorter than one minute for a prolonged time shortens the battery life.

Enabling and Disabling Logger Channels

The Logger Channels option permits you to enable or disable the channels on the currently-connected logger.
Note: During this process the logger’s memory is
cleared. If the information on the logger is still of value, transfer the data to a PC before enabling or disabling channels.
To enable or disable logger channels:
Select Logger | Channels.
1 2 In the window that appears, select or deselect the
checkbox to enable or disable a channel.
Click
OK. This initiates the process of clearing the log-
ger’s memory. To conserve logger memory it is a good idea to disable unused channels.
Note: If you are using a temperature and humidity log-
ger, remember that the humidity sensor requires temperature values; therefore, you cannot dis­able the temperature sensor channel if you are using the humidity channel.

Batch Setup, available in vLog VL, allows you to quickly configure several loggers with very similar settings. For example, using Batch Setup, you can quickly apply identical logger sample settings to all loggers in your environment.
To set up the first logger in a batch: 1 Ensure a logger is connected to your PC. 2 Choose Logger | Batch Setup.
46
3 Optional: Click Refresh to update the COM port list with
available ports.
4 From the Logger Batch Setup window, choose the COM
port your logger is communicating with and specify the number of COM ports in the range of your batch setup. (For example: If setting up loggers on COM ports 2, 4, and 6, the number of COM ports selected should read 5, not 3.)

Mounting Loggers
Because they are small and light, you can easily mount Vaisala Veriteq loggers in the field using a variety of techniques including Velcro strips, double-sided tape, duct tape, and magnetic strips.
In harsh environments, place the logger in a standard industrially-rated enclosure, and run external sensors and probes from the enclosure using special fittings in the openings.
Some tips for placing loggers:
Ventilation - Do not obstruct the air passage holes in the logger. There should be a clear path for the air to get to the internal sensors (if they are used or available).
Vibration - Excessive vibration can knock the unit off its mounting. If the location is subject to excessive jarring or vibration, mount the logger more securely.
Temperature - Excessive temperature (low or high) can affect adhesives.
48

Using External Temperature Probes

Moisture - Moisture can also affect the adhesive durability.
Permanence - Make sure the mounting location is permanent for the duration of the recording period.
Public access - If the logger location is too visible, people may interfere with the readings. Make sure it is not too accessible.
Using External Temperature Probes
Some Vaisala Veriteq loggers have external temperature channel(s) for use with an external temperature probe. Using the external temperature probe enables you to collect data from hard-to-get-at locations, such as in duct work or under pipe insulation.
You can use an external temperature probe with these loggers, provided the probe was calibrated with the logger.
To use an external temperature probe:
Enable the desired channel on the logger (see “Enabling
1
and Disabling Logger Channels” on page 39). If you do not need to monitor from the internal temperature sensor, disable it to conserve memory.
Note: You can disable most unused channels - exter-
nal probe or not - to conserve logger memory. One exception is the internal temperature chan­nel on VL-1700 and SP-1700 Data Loggers.
Vaisala Veriteq vLog 4.5 49

Caring for Relative Humidity Sensors

2 Attach the temperature probe to the connector on the
logger.
3 Use the Logger | Setup window to test the logger
operation (refresh the readings as required).
4 Place the logger in the desired location and start
recording.
Caring for Relative Humidity Sensors
Each Vaisala Veriteq SP- and VL-2000 Data Logger has a relative humidity sensor. Although the sensor has been designed to resist contamination and condensation, avoid exposing the logger to contaminants, if possible.

Chapter 3: Transferring Logger Files

This section provides details about:
• transferring logger data and setting transfer preferences
• generating a logger file creation report and ID number (vLog VL)
• setting the system date and time
• changing the time zone
• transferring logger data in batches to your PC (vLog VL)
Vaisala Veriteq vLog 4.5 51

Transferring Data

Transferring Data
When you transfer data from a logger’s memory, vLog creates a copy of the data and stores it on your PC as a logger file.
Logger transfers can be performed either individually (logger by logger) or in a batch (by selecting a range of COM ports using vLog VL).
Data from secure loggers (VL loggers) is stored in secure logger files. Data from non-secure loggers (SP loggers) is stored in non-secure logger files. All logger files have the .spl extension, logger files from SP loggers are non-secure and can be opened in vLog SP or vLog VL. Files from VL loggers are secure and can only be opened in vLog VL.
After inserting a logger file into vLog, you can view the information as a graph or as a tabular report.

VL Data Loggers (vLog VL)

During the data transfer process, vLog generates a Logger File Creation Report and a unique Logger File ID Number for VL-Series loggers. The Logger File ID Number also appears in the Logger file and on the graph and provides a convenient way to track the data from the logger to the final Graph file. The transfer process does not affect or delete the data in the logger.
Before transferring data, you may want to set the transfer preferences, and ensure that you have write permission to the folder on the PC where you are going to save your transferred data as logger files.
52

Setting Transfer Preferences

There are a variety of logger configuration preferences available to you:
• Configure the default file name format for logger files to help manage file storage.
• Configure vLog VL to display a Logger File Creation Report after the transfer. This report displays all the details of the transfer. It can be printed and it provides a secure and verifiable link between logger files and printed
© 2011 Vaisala Canada Inc
Transferring Data
records. This report is only produced for individual logger transfers, not for batch transfers.
• Configure vLog VL to interrupt batch transfer operations when an error is detected. If this option is not selected, vLog will skip over any errors that are detected and complete the batch transfer.
Note: In vLog 4.10, the Logger File Creation Report
feature was added to eliminate the need for using usernames and passwords to verify logger files. If you want to continue to configure vLog to prompt you for a username and password when you transfer data, see page 106.

Setting Sample Smoothing
In vLog, sample smoothing controls how samples in a logger file are interpreted when they are inserted into a graph, allowing you to dampen the effects of ‘noise’ in Logger files.
Sample smoothing is the minimum change in input signal required to cause a change in displayed channel values, and is defined in raw analog-to-digital converter counts.
vLog allows you to set two different sample smoothing values: one for thermocouple channels, the other for other channel types.
Note: Sample smoothing only affects how samples are
interpreted and presented in graphs and reports; the data in the loggers and the logger files is not

intervals and offset. For example, to show statistical summaries throughout the report every 12 hours at 8:00am and 8:00pm, set the interval to 12 hours, and the offset to 8 hours.
4 If including mean kinetic temperature in your report,
specify the activation energy for the item you’re monitoring temperature for. This value will be used in the mean kinetic temperature calculation. Enter the activation energy in kJ/mol.
5 Choose the statistics to include. Choose from maximum
values, average values, minimum values, standard deviation, mean kinetic temperature, lethality, sample count and/or group statistics. Group statistics is for showing data from channels of the same type (for example, temperature or humidity) together in one column.

If you’re including lethality in your report, specify the following values:
• reference temperature in degrees
• Z value in degrees (the Z value is the temperature required to change the D value by a factor of 10)
• D value in minutes (the D value is the time required to destroy 1 log cycle (90%) of the microbial population at the reference temperature)
7 Click OK. The report is displayed. Scroll through the
report to see your statistical information.

Audit Trail Reports (vLog VL)

3 Click OK to save your changes. When printed, the
Historical Data report will display the headers and/or footers you configured.
Audit Trail Reports (vLog VL)
The Audit Trail Report, available in vLog VL, contains information from the audit trail file. Audit trail files are similar to event logs, tracking operations that users perform in vLog so auditors can monitor changes to the vLog system. For example, the Audit Trail Report includes the time of an event, event type, severity, description, serial number and description of the logger involved, and computer and user name involved.
The Audit Trail Report is displayed in tabular format and can be saved as a file in multiple formats (see “Saving Reports” on page 102).
vLog also allows you to filter the Audit Trail Report, enabling you to show only events from certain dates, times, performed by certain users, or performed on certain loggers.
