Introduction
The LogTag® UTREL30-16 30-day Low-Temperature Data Logger with Display features a
display, USB connectivity, data logging memory storing up to 16065 temperature
readings per channel 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 following, alternating for each channel:
lThe current temperature (of the most recent reading)
lThe alarm status (within or outside the acceptance range)
lAn alarm trigger summary of up to the last 30 days (today and 29 days previous)
lThe current time and battery status
lMinimum and maximum temperatures since the start of the trip
Alarm events can be triggered when a number of readings are outside pre-set
temperature thresholds, and a “day alarm indicator” appears on the display.
Logged temperature data can be viewed on any PC by plugging the unit into a
computer’s USB port via a micro-USB cable. A PDF file is generated, which can be
accessed using free PDF software such as Acrobat Reader. The UTREL30-16 can also be
downloaded 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,
such as LogTag®Online.

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 13
Configuring the UTREL30-16 for logging
Before a UTREL30-16 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.

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 14
The logger is unconfigured
An unconfigured UTREL30-16 logger is delivered to you hibernated (i.e. in a state of low
power consumption), and pressing the REVIEW/MARK button shows:
and then

If your logger is unconfigured you must set it up with the parameters required for
lstarting and recording temperature values;
lprinting the PDF; and
ltriggering alarms.
This is done using LogTag® Analyzer software, which can also be used for downloading
and analyzing data:
lStart the LogTag® Analyzer software.
lRemove the protective cap from the logger's USB socket and plug the Micro USB
end of the cable into the socket. Plug the other end of the cable into a USB socket
on your computer and wait for the drivers to be installed1.
lFrom the menu click LogTag - Configure; LogTag® Analyzer will display the
configuration options for connected loggers.
1 You can configure more than one UTREL30-16 at the same time, however it is practical to limit the number of units to about 6,
using a powered USB hub.

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 15
Standard Configuration Settings
The standard configuration is similar to those of other LogTag® logger products and
includes settings such as User ID, start method, pre-start recording, logging interval
and duration, start delay, and password.
Figure 1: Standard configuration parameters for a UTREL30-16
Adjust the settings as required. 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.
In this section you also decide which channels the UTREL30-16 will record. Select CH1
only or CH2 only if you only wish to record temperatures measured by a single probe
(plugged into the corresponding socket marked CH1 or CH2) , or select Both for
recording both probes.
UTREL30-16 Start Options
During configuration with LogTag® Analyzer you can decide when the UTREL30-16 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32).
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 UTREL30-16 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, pre-start readings will not
appear in the PDF file after the logger was started, and no PDF file will be generated if

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 16
only pre-start readings are present in the logger. 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 UTREL30-16 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.
Alarm Configuration Options
The UTREL30-16 can display an alarm if one or more of the configured alarm trigger
conditions have been met. This is indicated on the display by showing the Alarm
Indicator and a Day Alarm Marker.
is shown for an alarm triggered today, other markers are shown for alarms triggered
on previous days, see Day Alarm Matrix Display while recording for details on which
marker is displayed for which day. Alarms are registered separately for each channel,
and will only be shown on the corresponding channel's screen. Additionally, the red
LED will blink every 4 seconds. The LED blinks until active Alarms on both channels are
cleared.

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 17
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 entered in the Alarm Settings tab during configuration
of the logger with LogTag® Analyzer. Alarms are configured separately for each channel.
If you have chosen to log only one of the channels, the controls for the other channel
are not available.
The screen shows an example where:
lthe upper primary alarm for channel 1 is triggered when the temperature is -
70.0°C or above for an accumulative time of 10 hours.
lthe lower primary alarm for channel 1 is triggered when the temperature is -
80.0°C or below continuously for 1 hour.

Instant = one temperature reading is above (below) the threshold
l
Consecutive = temperature readings are above (below) the threshold for the time defined in the activation delay without
interruption
l
Accumulative = temperature readings are above (below) the threshold for the total time defined in the activation delay
time, but may not necessarily be sequential

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 18
Once an alarm has triggered, the alarm indicator ( ) remains shown until the alarm is
cleared (see Clearing an Alarm on page39) 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.
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.
