Introduction TRED30-16R User Guide 4

Introduction

The LogTag® TRED30-16R temperature logger features a data logging memory storing up to 15,905
temperature readings and a separate statistical memory, storing maximum and minimum reading as well
as alarm duration for each of the last 30 days.
During recording the display shows the temperature of the most recent reading, whether or not this is within
or outside the acceptance range, an alarm trigger summary of the last 30 days (today and 29 days
previous), the current time and battery status.
Alarm events can be triggered when a number of readings are outside preset Alarm thresholds and a “day
alarm indicator” appears on the display.
Logged temperature data can be downloaded via a standard LogTag® Interface to the free companion
software LogTag® Analyzer, where you can display data in chart, list or summary formats. The software
also allows electronic archiving and exporting or transmitting data in support of sophisticated data
management systems.

Configuring the TRED30-16R TRED30-16R User Guide 6

Configuring the TRED30-16R

Before a TRED30-16R logger can be used, it must be configured with the parameters required for starting
and recording temperature values . This is done using LogTag® Analyzer software, which is also used for
downloading and analyzing data.

l Start the LogTag® Analyzer software.
l Plug a LogTag® interface cradle into a USB port and wait for the drivers to be installed. You can use

more than one cradle to configure multiple devices at the same time, however it is practical to limit
the number of units to about 6, using a powered USB hub.

l Insert the TRED30-16R into the interface with the three contacts towards the back until it clicks in

place.

l Select LogTag - Configure; LogTag® Analyzer will display the configuration options for any connected

TRED30-16R loggers.



Standard Configuration Options

The standard configuration options are very similar to those of other LogTag® logger products and include
settings such as User ID, start method, pre-start recording, logging interval and duration, start delay, and

password.

For detailed information about each parameter please read the section about Configuring a LogTag® for
logging in LogTag® Analyzer’s User Guide or press F1 for help.

Standard Configuration Options TRED30-16R User Guide 7

TRED30-16R Start Options

During configuration with LogTag® Analyzer you can decide when the TRED30-16R starts taking
temperature readings.

l ... via Push button start: The logger will start taking temperature readings after you have gone through

a specific start sequence of pressing and releasing the START/CLEAR/STOP button (see Starting the

Logger on page13).

l ... via Date/Time start : The logger will start taking temperature readings at the date and time you

specify (local time).

When you choose the push button start option, you can select to record pre-start readings or Begin

recording after a delay.

l If you configure the TRED30-16R to start after a delay period, the logger will not immediately record

temperature readings after you have pressed START/CLEAR/STOP, but start a countdown timer
instead, and record readings only after the timer has ended. It will, however, continue to take pre-start
readings, if enabled.

You cannot combine a date/time start with pre-start readings or the start delay function.

Audible Alarm

The TRED30-16R is fitted with a buzzer, which can be turned on when an alarm event has been registered
to provide extra feedback. This function is enabled or disabled when configuring the logger with LogTag®
Analyzer.

Please note, that continual activation of the audible alarm will reduce the working life of the
battery. When an alarm event is triggered, the alarm should be cleared as soon as possible.

The alarm will sound once every four seconds for the first 24 hours. To preserve battery life, the interval at
which the alarm sounds will increase to 8 seconds when the clock passes midnight after the initial 24 hour
period (i.e. the alarm will sound every 4 seconds between 24 and 48 hours, depending on when during the
day the alarm was first triggered). When the clock passes midnight again, the interval changes to 12
seconds. It will remain at 12 seconds until the alarm is cleared, the unit stops or is re-configured.

Note: The interval will increase, even if the alarm is re-triggered!
Please see more information about Alarm Re-triggering on the next page

The beeper will temporarily turn off when you are reviewing data.

Standard Configuration Options TRED30-16R User Guide 8

Alarm Configuration Options

The TRED30-16R can display an alarm if either of the configured alarm trigger conditions have been met.
This is indicated on the display by showing the Alarm Indicator ( ) and the Day Alarm Marker for today ( ).

Each alarm trigger condition consists of a threshold temperature value, an activation type (which can be
instant, consecutive or accumulative1) and a delay time, if it is not an instant alarm.
If an alarm trigger condition requires readings to exceed an upper threshold temperature it is called an

upper alarm. If an alarm trigger condition requires readings to go below a lower threshold it is called a lower
alarm.

All alarm trigger conditions are configured in the Alarm Settings tab during configuration of the logger with
LogTag® Analyzer.
The screen shows an example where:

l the upper alarm is triggered when the temperature is 10.0°C or above for an accumulative time of 10

hours.

l the lower alarm is triggered when the temperature is -0.5°C or below continuously for 1 hour.

Figure 2: Sample Alarm Configuration Settings for the TRED30-16R

Once an alarm has triggered, the alarm indicator ( ) remains shown until the alarm is cleared (see Clearing

an Alarm on page17) or the unit is reconfigured. The day alarm marker remains shown until midnight,

then it turns off and the marker for the previous day is shown ( ) to indicate the alarm was registered
against what is now the previous day. When midnight passes next, this marker will move to and so on.

Note: As soon as an alarm is triggered, the corresponding delay time (but not any others) resets to
zero and starts again. The alarm processing for all other alarm delays is not affected. Therefore,
accumulative or consecutive alarms will re-trigger, if the alarm conditions are met again, and the
Alarm Indicator ( ) and the Day Alarm Marker ( ) will be shown, even if any previous alarm was
cleared. Clearing an Alarm does not reset any of the delay values.

Real Time Clock TRED30-16R User Guide 12

Real Time Clock

The time shown on the recording display is linked to the logger’s internal real time clock.
A day change occurs when the display time rolls through midnight (i.e. 00:00). This is the primary function
of the display clock.
Each time the logger is configured with LogTag® Analyzer the display clock value is set to the PC's current
local time (or timezone).

Note that the logger’s internal real time clock value is only updated when the recorder is
configured with LogTag® Analyzer. This prevents the data logging becoming discontinuous, which
would be the case if the real time clock were to be changed together with the display clock.

LogTag® Analyzer can display the logged readings in a number of different time zones, regardless of where
it was configured. Please note, however, that the PDF's time zone has to be set at configuration and cannot
be changed after the logger has been downloaded.

Adjusting the Display Clock

The display clock of the logger can be set to the current local time, either by using LogTag® Analyzer
software or directly on the unit, using the buttons.

To set the clock, press and hold the
buttons together continuously for a period of 8 seconds. Press the buttons firmly!
During this period the CLOCKADJ icon flashes. Release the buttons when the flashing stops. The clock
can now be adjusted.

Initially, the minutes digits flash.

Press the button to increment the minutes digit (once it reaches

59 it rolls back to 00 on the next press).

Accept the minutes value by pressing . The hours value now

button, then press and hold the button. Keep holding both

NOTE: It is advised that the real time clock is only adjusted when the product is not recording
(STOPPED or READY) to avoid large shifts in day boundary data.

If a display clock adjustment is made while in RECORDING mode, the next log taken will be
identified in the downloaded data with a time change mark.

Changes to the display clock do not affect the internal real time clock value, so the logged data does not
show time gaps.

During Recording TRED30-16R User Guide 16

During Recording

During normal operation the display shows the most recently recorded temperature. This temperature is
updated at the same rate as the logging interval. The current time is also displayed (in 24 hour format). A
tick symbol is shown as long as no alarm event has occurred. If an alarm event is registered, a cross
symbol is shown instead of the tick.
At the bottom of the display you can see an alarm day summary, where any days on which an alarm was
recorded are highlighted.
Following are some sample display screens:

At 1:29 pm the display shows the following:

l Alarm events were recorded 7, 19, 20 & 25 days ago
l These alarms were cleared by an inspector, as the display currently shows the OK tick ( ).
l The current temperature is over the upper alarm threshold, as indicated by the upper alarm marker (

).

l the duration, however, of this temperature excursion has not yet triggered an alarm

At 1:49pm (20 minutes later) the display shows the following:

l The temperature has remained above the upper alarm threshold and has now triggered an alarm

event.
l The alarm symbol is shown to indicate an alarm event occurred
l The day marker for the current day ( ) is shown.

At 1:49am on the next day the display shows the following:

l The temperature has returned to within the accepted range (none of the alarm threshold markers are

visible), but the alarm remains present, as it has not been inspected and cleared
l The day summary has shifted by 1 day as the display time has passed through midnight (00:00).

Marking a reading with an inspection mark

When you press the REVIEW/MARK button, the next reading taken by the TRED30-16R will be identified in
the downloaded data with an inspection mark.

A mark will be placed in the readings when you clear an alarm.

Note: Only the Alarm Indicator ( ) can be cleared! The day alarm marker ( in the above
example) remains shown, as it is part of the statistic summary. Clearing an alarm also does not
reset any of the delay values. Please see

Alarm Configuration for additional information.

Paused Readings

During configuration of the TRED30-16R you can set the option to ignore up to 15 readings for alarm- and
statistics calculations after either button is pressed. The readings are still shown on the graph and in the
data listing, but they are labelled as paused, and their value is ignored when determining alarm trigger
conditions, minimum/maximum values and other statistical calculations.

This function is useful, for example, when you wish to temporarily remove the sensor from the
monitored location to inspect goods, but you do not wish to trigger an alarm due to your handling.

It also allows the logger to acclimatise to the environmental conditions again, before further readings are
processed.

After a button press the display shows the word PAUSED next
to the symbol.

The option is set in the Advanced Settings tab during
configuration with LogTag® Analyzer and is expressed in
number of readings after the last button press.
Paused readings are specially marked in the graph and data
listings.
.

PAUSED will turn off as soon as the last ignored reading has been recorded. It will show longer, if your last

button press was just after the logger took a temperature reading, but will be displayed for a shorter period if
you pressed the button just before a reading is taken. For example, if you configure a logging interval of 10
minutes and 2 paused readings, the time for PAUSED to show could be as short as 10 minutes, but as
long as 20 minutes.

Sensor is disconnected

The display shows --.-, if the external sensor of the TRED30-16R is disconnected. This function is useful
if the sensor is permanently mounted , but you wish to take the TRED30-16R to a computer for downloading
its data.

Any values recorded during the time the sensor is
disconnected will not be taken into account when calculating
statistics values or alarms.
If, for example, the temperature was above 10°C for 12 hours
(which would normally trigger an alarm event), but the sensor
was disconnected for 3 hours during this time, no alarm would
be generated.
After downloading the TRED30-16R with LogTag® Analyzer,
any readings taken while the sensor is disconnected are
shown as --.- in the data list. The graph will show a gap during
this period.
If the sensor was disconnected for a complete day, the
minimum and maximum statistics for that day will show --.­on the display and --.- on the list.

Power Save

When Power Save is enabled, the display will automatically switch off if none of the buttons have been
pressed for 30 seconds.
This function is appropriate in applications where you don't need to look at the display frequently, such as in
transit monitoring applications, as the logger uses less battery power when the display is not turned on.
Pressing any button will re-activate the display.

Power save is enabled or disabled when configuring the TRED30-16R via LogTag® Analyzer in the

Advanced Settings tab.

Total Number of Days Statistics Collected

The logger can be configured to show the total number of days for which statistics data was collected. This
feature is enabled when configuring the TRED30-16R via LogTag® Analyzer and can be located in the

Advanced Options dialogue (see Advanced Configuration Options on page9).

When enabled, the total number of days for which statistics data was collected are shown on both the

Recording Display and the Stopped Display.

Figure 6: TRED30-16R stopped, showing ‘27’ days of data has been collected.

Note, this is not always the number of days the logger has collected data. Depending on the
sampling interval the logger can hold more than 30 days of temperature readings, but since the
maximum number of days for which statistics can be collected is 30, the highest number that can
be shown here is 30.

button. The READY symbol will flash.

Hibernating a TRED30-16R

When hibernated, the logger’s power consumption is near zero and the life of the battery approaches its
shelf life (typ. 5 or more years).
This is useful for conserving battery life when the logger is not used for extended periods .
TRED30-16R loggers are placed into Hibernation using LogTag® Analyzer by clicking Hibernate on the
LogTag menu.
The display shows SLP for a few seconds, before turning itself off.

A hibernated logger has no active display, however a button press will wake the logger up briefly. The
display will show:

A hibernated logger can be activated again by pressing and holding the and buttons together for a
period of 6 seconds. During this time the text not rdY appears and the READY symbol flashes. Release the

buttons when the flashing stops.

You can re-activate a logger with a low battery, however it is not recommended to commence another trip.

Note: The real time clock is not running in a hibernated logger and must be set up if the logger is
manually activated. Therefore, the CLOCKADJ procedure is automatically invoked (see Adjusting

the Display Clock on page12).

Once the clock has been set, the logger is ready to be started again.
