Introduction TREL30-16 User Guide 6
Introduction
The LogTag® TREL30-16 low 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, including
LogTag®Online.

Configuring the TREL30-16 for logging TREL30-16 User Guide 9
Configuring the TREL30-16 for logging
Before a TREL30-16 logger can be deployed, it must be configured with the parameters
required for starting and recording temperature values.
Loggers can be purchased unconfigured, or pre-configured, ready to be started, using one
of a number of different profiles that are available.
You can check if your logger is already configured or not by briefly pressing the
REVIEW/MARK button.
The logger is already configured to start
If your logger is configured to start it will show either
if the logger was pre-configured for a push-button start, or
if the logger was pre-configured for a Date/Time start.
If your logger shows one of these screens you may skip the configuration process.
The logger is unconfigured
An unconfigured TREL30-16 logger is delivered to you hibernated (i.e. in a state of low
power consumption), and pressing the REVIEW/MARK shows:
and then

Standard Configuration Options TREL30-16 User Guide 10

If your logger is unconfigured you must set it up with the parameters required for:
lstarting and recording temperature values
ltriggering alarms
This is done using LogTag® Analyzer software, which can also be used for downloading and
analyzing data.
Standard Configuration Options
The standard configuration options 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 TREL30-16 User Guide 11
TREL30-16 Start Options
During configuration with LogTag® Analyzer you can decide when the TREL30-16 starts
taking temperature readings:
Push button start
The logger will start taking temperature readings as soon as you have pressed the
START/CLEAR/STOP button (see Starting the Logger on page19).
When you choose the push button start option, you can Enable pre-start logging (or
disable it) and also Begin recording after a delay.
Pre-start readings
If you enable pre-start readings, the TREL30-16 starts recording as soon as it is configured
and will continue to do so until you start the unit via the button. No alarms are processed
while pre-start readings are being taken. Using pre-start readings is a good way to avoid
data loss if you forget to start the unit, as you can still access the data using LogTag®
Analyzer.
Start delay
If you configure the TREL30-16 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. The
value for the timer is set during configuration. If pre-start readings are enabled, these will
continue to be recorded during the delay period.
Date/Time start
The logger will start taking temperature readings at the date and time you enter during
configuration (local time). You cannot combine a date/time start with pre-start readings or
the start delay function.
Audible Alarm
The TREL30-16 is fitted with a buzzer. You can choose to activate the buzzer when an
alarm event has been triggered to provide extra feedback. This is enabled or disabled in the
Advanced Settings 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.

Standard Configuration Options TREL30-16 User Guide 12
The alarm will sound once every four seconds for the first 24 hours, then sound less
frequently to preserve battery life1 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 re-triggering alarms in
The buzzer will temporarily turn off when you are reviewing data.

1 The interval at which the alarm sounds will increase to 8 seconds when the clock passes midnight for a second time (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 a third time, the interval changes to 12 seconds until the alarm is cleared.

Standard Configuration Options TREL30-16 User Guide 13
Alarm Configuration Options
The TREL30-16 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 accumulative2) 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:
lthe upper alarm is triggered when the temperature is -70.0°C or above for an
accumulative time of 10 hours.
lthe lower alarm is triggered when the temperature is -80.0°C or below continuously
for 1 hour.
Once an alarm has triggered, the alarm indicator ( ) remains shown until the alarm is
cleared (see Clearing an Alarm on page25) or the unit is reconfigured. The day alarm
marker remains shown until midnight, then it turns off and the marker for the
2
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

Standard Configuration Options TREL30-16 User Guide 14
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.
Alarm Re-triggering
A note on alarm re-triggering: As soon as an alarm is triggered, the corresponding
delay time (but not any others) resets to zero and alarm processing 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 TREL30-16 User Guide 18
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), which
triggers the statistical data to be finalized for the day, and a new day to be started when
the next reading is taken.
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.
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 START/CLEAR/STOP ( ) button, then immediately press
and hold the REVIEW/MARK ( ) 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).

Starting the Logger TREL30-16 User Guide 19
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 the product is
not recording (STOPPED or READY) to avoid large shifts in day boundary data.
If a display clock adjustment is made while recording data, 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.
