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 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;
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.
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.
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29).
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
unplugged from the USB port2 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 only pre-start readings are present in the logger. Using pre-start readings is a

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 16
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.
Automatic start via LogTag®Online
The logger will start as soon as it has received configuration settings via the locations's
Logger configuration profile. Depending on the profile settings, it may start taking
temperature readings instantly, or after a delay period.
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 the Day Alarm Marker for today ( ). Additionally, the red LED will blink every 4
seconds.
Each alarm trigger condition consists of a threshold temperature value, an activation type
(which can be instant, consecutive or accumulative3) and a delay time, if it is not an
instant alarm.
3
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

Preparing a UTREL30-16 for first use UTREL30-16 User Guide 17
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 primary alarm is triggered when the temperature is -70.0°C or above for
an accumulative time of 10 hours.
lthe lower primary 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35) 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.
