The LogTag® TRED30-16R temperature recorder 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 current temperature (of the
most recent reading), the status (within or outside the acceptance
range), an alarm trigger summary of up to the last 30 days (today and
29 days previous) of recording, the current time and battery status.
Alarm events can be triggered when a number of readings are outside
pre-set 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.

Introduction

Standard Configuration Options
The standard configuration options are very similar to those of other
LogTag® recorder products and include settings such as User ID,
start method, pre-start recording, logging interval and duration,
start delay, temperature alarm parameters and password.
Figure 2: TRED30-16R Standard Configuration Options
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.
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 recorder 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 Recorder on page 9).
l... via Date/Time start : The recorder 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.
lIf you configure the TRED30-16R to start after a delay period, the
recorder 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.
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.
The alarm triggering structure in the recorder supports many
different alarm trigger configurations.
For example, a possible alarm trigger configuration could be:
lUpper alarm is triggered when the temperature is 10°C or above
for an accumulative time of 10 hours.
lLower alarm is triggered when the temperature is -0.5°C or below
continuously for 1 hour.
Figure 3: Sample Alarm Configuration Settings
All alarm trigger conditions are configured using LogTag® Analyzer,
please see the Standard Configuration Options above.
Once an alarm has triggered, the alarm indicator ( ) remains
shown until the alarm is cleared (see Clearing an Alarm on
page 10). 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 mignight passes next, this marker will move to
and so on.
Once an alarm event occurred, all alarm counters are reset, and the
alarm processing starts again. 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 once
again.
Alarm Re-triggering
1
lInstant = one temperature reading is above (below) the threshold
lConsecutive = temperature readings are above (below) the threshold for the
time defined in the activation delay without interruption
lAccumulative = temperature readings are above (below) the threshold for the
total time defined in the activation delay time, but may not necessarily be
sequential.

Audible Alarm
The TRED30-16R is fitted with a beeper, which can be enabled to
provide extra feedback when an alarm event has been registered. This
function is enabled when configuring the recorder with LogTag®
Analyzer, please see the Standard Configuration Options on the
previous page or the Audible Alarm above.
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 two seconds for the first 24 hours. To
preserve battery life, the interval at which the alarm sounds will
increase by 2 seconds each time the clock passes midnight after the
initial 24 hour period (i.e. the alarm will sound every 2 seconds
between 24 and 48 hours, depending on when during the day the
alarm triggered, then every 4 seconds for a day, then every 6 seconds
and so on).
Once the interval has reached 10 seconds, it will no longer increase.
Note: The interval will increase, even if the alarm is re-triggered!
Please see more information about Alarm Re-triggering on the
previous page

Temperature
This 4 character, 7-segment display shows the last recorded
temperature while the TRED30-16R is recording . Once the recorder
has stopped, nothing will be displayed.
Temperature Units
Depending on the selected display temperature units during
configuration, this shows either °F or °C.
ALARM/OK indicator
The symbol is shown as soon as the TRED30-16R has registered an
alarm event. If no alarms have been registered, or if an existing alarm
has been cleared, the symbol is shown.
Alarm Threshold Markers
The up-arrow is shown when the temperature displayed (i.e. last
recorded) is above the specified upper temperature threshold. The
down-arrow is shown when the temperature displayed is below the
specified lower temperature threshold.
Recording state indicators
The recording state indicators show if the TRED30-16R is currently
recording data.
lIf the READY symbol is shown, the TRED30-16R is ready to be
started. Depending on the configuration it may already record pre-
start readings.
lIf the STARTING symbol is shown, the recorder has been
configured with a start delay. The word DELAY is also shown,
together with the time in hours and minutes until the start.
lIf the symbol is shown, the TRED30-16R is recording
temperatures at the sample interval defined during configuration
with LogTag® Analyzer.
lIf is shown together with the word PAUSED, the product is
also recording, but the recorded values are not taken into account
when calculating alarm events and durations.
lIf the word STOPPED is shown, the TRED30-16R has finished
recording temperature data.
Battery Low
A battery test is performed hourly. The battery low symbol will
appear if the TRED30-16R's battery is low and requires changing.
Please follow the instructions provided in Appendix 1 - Battery
Replacement on page 16. If the symbol is not shown while the display is
turned on, the battery is still OK.
Time Value and Time Indicators
The time value display is used to show one of the following:
la clock with the current time,
ltime remaining to start of logging with a delayed start or
lduration, for example of an alarm.
The time indicators identify, which of those is displayed:
lIf the word TIME is shown, the time value represents the current
time in hours and minutes (24- hour format).
lIf the word DELAY is shown, the time value represents a start
delay in hours and minutes.
lIf the word DURATION is shown, the time value represents the
length of time in hours and minutes an alarm threshold was
exceeded, for example the time above the upper alarm threshold.
The word dtstappears in place of a time value if the recorder is
configured for a date/time start, and the start time has not yet passed.
Reading Type
The word CURRENT is shown when the temperature on the display
represents the last recorded temperature.
The word MAX is shown in Review mode, when the temperature on
the display represents the maximum recorded temperature for the day
displayed.
The word MIN is shown in Review mode, when the temperature on the
display represents the minimum recorded temperature for the day
displayed.
Day Alarm Markers
This grid shows 3 rows of 10 markers, named Today ( ) to Day -29 (
), which are switched on when an alarm event occured on that day.
Day Number
During Review, this shows the day number of the currently displayed
day statistic. Today is 00DAYS, days in the past are represented
between yesterday -01DAYS and -29DAYS. During configuration of
the recorder in LogTag® Analyzer you can also enable this to show the
total number of days on which data were collected while recording.

Real Time Clock
The time shown on the recording display is linked to the recorder’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 recorder is configured with LogTag® Analyzer the display
clock value is set to the PC's current local time (or timezone). The time
can also be adjusted directly on the unit using the buttons (see
Adjusting the Display Clock below).
Note that the recorder’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 the following
times:-
lUTC (GMT)
lConfiguration time zone
lDownload timezone
lDisplay clock timezone (default)
Adjusting the Display Clock
The display clock of the recorder can be set to the correct time, either
by using LogTag® Analyzer software or directly on the unit, using the
buttons.
To set the clock, press and hold the button, then press and hold
the button. Keep holding both 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
flashes.
Press the button to increment the hours digits (once it reaches 23
it rolls back to 00 on the next press).
Accept the hours value by pressing . The new clock value is now
stored, and the display shows the normal screen.
NOTE: It is advised that the real time clock is only adjusted when in
STOPPED or READY modes (i.e not recording) 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.

Starting the Recorder
Push button start
The recorder must be in READY mode for it to be started.
Current time and the READY symbol are shown.
Press and hold the START/CLEAR/STOP button. First, STARTING
is shown in addition to READY:
Then READY disappears:
Once READY disappears, release the button within two seconds.
STARTING will also disappear, and the symbol will be shown.
The TRED30-16R now records temperature data.
The recorder will not start if you…
… release the button before READY disappears
… keep holding the button for more than 2 seconds after READY
disappears.
Push Button Start with Start Delay
If the recorder has been configured for push button start with a start
delay, the word DELAY is shown instead of the symbol.
The delay time is shown in hours and minutes.
The time counts down and the TRED30-16R starts recording when it
reaches 0:00.
If a user presses the START/CLEAR/STOP button during the start
delay phase, the start delay value is reset to its originally configured
value.
Automatic date/time start
If you configured the TRED30-16R for a date/time start, it will start
recording temperature values as soon as the entered start time is
reached.
The recorder will display the following if a Date/Time Start has been
chosen:
Hibernating the recorder using LogTag® Analyzer will disable the
Date/Time start function.

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 occured. 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:
lAlarm events were recorded 7, 19, 20 & 25 days ago
lThese alarms were cleared by an inspector, as the display currently
shows the OK tick ( ).
lThe current temperature is over the upper alarm threshold, as
indicated by the upper alarm marker ( ).
lthe duration, however, of this temperature excursion has not yet
triggered an alarm
At 1:49pm (20 minutes later) the display shows the following:
lThe temperature has remained above the upper alarm threshold
and has now triggered an alarm event.
lThe cross symbol is shown to indicate an alarm event occurred
lThe day marker for the current day ( ) is shown.
At 1:49am on the next day the display shows the following:
lThe temperature has returned to within the accepted range (none
of the alarm markers are visible), but the alarm remains present, as
it has not been inspected and cleared
lThe 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.
An inspection mark will also be recorded if you clear an alarm.
Clearing an Alarm
During configuration with LogTag® Analyzer you can allow a user to
clear an alarm on the display. This is a useful function for an inspector,
so new alarms can be recognised easier.
This display screen shows an existing alarm that occurred yesterday,
but has not yet been cleared:
To clear this alarm, press and hold the START/CLEAR/STOP button.
After approx. 2 seconds the cross will be replaced with the tick .
Release the button when the tick appears. The normal recording
display is shown.
In this example the paused function was activated, and the paused
symbol is shown on the display. For more information about paused
readings please see the section about Paused Readings below.
The alarm will not be cleared if you release the button before the cross
disappears.
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.
Paused Readings
During configuration of the TRED30-16R you can set the option to
ignore a set number of 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 an other statistical calculations. This
function is useful when you wish to review readings during the
recorder's operation (or clear an alarm), but you do not wish to trigger
an alarm due to your handling the product. It also allows the recorder to
Page 10 of 16 TRED30-16R Product User Guide, Revision 1.3, copyright © 2004-2016, LogTag®Recorders . All rights reserved.

acclimatise to the environmental conditions again, before further
readings are processed.
After a button press the display shows the word PAUSED next to the
recording symbol.
Paused readings are specially marked in the graph and data listings.
The option is set in the advanced options dialogue in LogTag® Analyzer
during configuration and is expressed in number of readings after the
last button press (see Advanced Configuration Options on page 6).
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
recorder took a temperature reading, but will be displayed for a shorter
period if you pressed the button just before a reading is taken. With the
options configured in the example on page 5on page 6 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 TRED30-16Ris
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 diconnected 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 durign 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.
Power Save
When Power save mode is enabled, the display will automatically
switch off after 30 seconds of no button activity.
The recorder uses significantly less battery power with the display off
(typically only around 1/3 of the average power with the display on).
This function is appropriate in applications where the current
temperature display is not required to be seen frequently, such as in
transit monitoring applications.
Pressing any button will re-activate the display.
The power save mode is enabled or disabled when configuring the
TRED30-16R via LogTag® Analyzer in the Advanced Options dialogue
(see Advanced Configuration Options on page 6).
Total Number of Days Statistics Collected
The recorder 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 6).
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 recording, showing ‘18’ days of data has been collected.
Figure 7: TRED30-16R stopped, showing ‘27’ days of data has been collected.
Note, this is not always the number of days the recorder has collected
data. Depending on the sampling interval the recorder 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.

Reviewing Day Statistics on the
TRED30-16R
The review of day statistics history is accessed by pressing the
REVIEW/MARK button .
You can review the data regardless of whether the recorder is still
logging data, or has already been stopped.
Following are some sample display screens you might see during a
statistics review. All display screens are based on the alarm settings
made in Alarm Configuration Options on page 5:
Today's data
Pressing the button displays the current day’s maximum statistic:
lThe Today marker flashes and 00 DAYS is shown to indicate
that today's data are being displayed.
lToday, no temperature values were recorded above the upper alarm
threshold, and no alarm event was generated ( ).
lThe maximum temperature recorded today was 4.8°C.
lThe paused function is enabled
Pressing the button again displays the current day’s minimum
statistic:
l still flashes and 00 DAYS is still shown, as the same day's
data (today) is being displayed.
lToday, no temperature values were recorded below the lower alarm
threshold, and no alarm event was generated.
lThe minimum temperature recorded today was 1.4°C.
Yesterday's data
Pressing the button now displays yesterday’s maximum statistic:
lThe -1 marker flashes and -01 DAYS is shown to indicate that
yesterday's data is being displayed.
lYesterday, recordings above the upper threshold were recorded,
indicated by the upper alarm threshold marker
lthe duration value shows the amount of time recorded above the
limit yesterday, which was 12 hours 30 minutes
lan alarm was triggered, indicated by the , as this duration was
longer than the allowed time above the threshold
lThe maximum temperature recorded yesterday was 12.9°C.
Pressing the button now displays yesterday’s minimum statistic:
l still flashes and -01 DAYS still shows, as we are still looking
at yesterday's data.
lYesterday, no temperature values were recorded below the lower
alarm threshold. The alarm for the day was generated by the
upper alarm, not by the lower alarm, so a is displayed in the
minimum statistics.
lThe minimum temperature recorded yesterday was 2.0°C.
Data from the day before yesterday
Pressing the button now displays the maximum statistic from two
days ago:
lThe flashes and -02 DAYS is shown to indicate that the data
being displayed is from two days ago.
lTwo days ago recordings above the upper threshold were recorded,
indicated by the upper alarm threshold marker
lThe duration was 1 hour 20 minutes, which was shorter than the
allowed period, so no alarm event was generated
lThe maximum temperature recorded on the day before yesterday
was 11.5°C.
Pressing the button now displays the minimum statistic from two
days ago:

Data from 7 days ago
After pressing the button for a few times (skipping days -3 to -6)
the maximum statistic from seven days ago is displayed:
lThe flashes and -07 DAYS is shown to indicate that the data
being displayed is from seven days ago.
lSeven days ago recordings above the upper threshold were recorded,
indicated by the upper alarm threshold marker
lThe duration was 6 hour 30 minutes, which was shorter than the
allowed period, so no alarm event was generated
lThe maximum temperature recorded seven days ago was 10.5°C.
Data from 8 days ago
After pressing the button twice (skipping the minimum statistics
for day -7) the maximum statistic from eight days ago is displayed:
lThe flashes and -08 DAYS is shown to indicate that the data
being displayed is from eight days ago.
lEight days ago recordings above the upper threshold were recorded,
indicated by the upper alarm threshold marker
lThe duration was 5 hour 30 minutes
lAn alarm event was generated . Neither duration from day -7 or -
8 by itself would cause an alarm event, however the combined
duration is 10 hours 50 minutes, which is more than the allowed 10
accumulative hours.
lThe maximum temperature recorded eight days ago was 11.5°C.
Tip: Pressing and holding the button will get you back to the
previous screen, rather than advancing one screen.
Stopping the TRED30-16R
Automatically
The TRED30-16R automatically stops recording temperature when the
maximum number of readings specified during configuration has been
reached. Your unit can also be set up to stop automatically when it is
downloaded. This option needs to be set up at the factory and cannot
be changed during configuration with LogTag® Analyzer. Your
distributor can supply more information about this option.
Manually
You can configure a TRED30-16R so it can be stopped with the
START/CLEAR/STOP button. This feature is useful when you take the
recorder out of a shipment and don’t want to falsify the statistics with
readings taken after the shipment completion. The stop function is
enabled in the Advanced Options dialogue during configuration (see
Advanced Configuration Options on page 6). When enabled, following
will stop the unit:
Press and hold the START/CLEAR/STOP button. STOPPED is
shown in addition to the symbol.
Then the symbol disappears:
Once the symbol disappears, release the button within 2 seconds.
The recorder will now stop taking readings.
The recorder will not stop if you…
… release the button before the symbol disappears
… keep holding the button for more than 2 seconds after the
symbol disappears.

If an ALARM is present ( ) and the Clear alarm by pressing STOP
button function is enabled, you will need to clear the alarm first
before you can stop the recorder. Please see Clearing an Alarm on
page 10 for more information on how to clear an alarm.
Resetting the Recorder
You can reset a recorder back to its original READY state.
Once re-set, recording can be started again as described in Starting the
Recorder on page 9.
Note that when performing this procedure all recordings and
statistics stored in the recorder are deleted and cannot be recovered.
Please ensure your data has been saved!
For this process to work, the recorder must be in the STOPPED state.
lPress and hold the button. The READY symbol will flash.
lWhen the READY symbol remains permanently on, release the
button within 2 seconds. The recorder is now ready to be started
again.
The ability to reset a recorder is enabled or disabled in the Advanced
Options dialogue when configuring the TRED30-16R via LogTag®
Analyzer (see Advanced Configuration Options on page 6).
Hibernating a TRED30-16R
When hibernated, the recorder’s power consumption falls to near zero
and the life of the battery approaches its shelf life (typically 5 or more
years).
This is useful for conserving battery life when the recorder is not used
for extended periods .
TRED30-16R recorders are placed into Hibernation using LogTag®
Analyzer by clicking Hibernate on the LogTag menu.
The disply shows SLP for a few seconds, before turning itself off.
A hibernated recorder has no active display, however a button press will
wake the recorder up briefly. The display will show:
lthe low battery symbol if the battery requires replacing.
lthe text not rdY if the battery is OK, and the recorder can be re-
activated at a later point.
A hibernated recorder can be activated again by pressing the and
buttons together continuously for a period of 6 seconds.
During this time the text not rdY appears and the READY icon
flashes. Release the buttons when the flashing stops.
You can re-activate a recorder with a low battery, however it is not
recommended to commence another trip.
Note: The real time clock is not running in a hibernated recorder and
must be set up if the recorder is manually activated. Therefore, the
CLOCKADJ procedure is automatically invoked (see Adjusting the
Display Clock on page 8).
Once the clock has been set, the recorder is ready to be started again.
