Getting Started UTREL-16 User Guide 11
Getting Started
Figure 1: LogTag® recording cycle
Your LogTag® data logger is typically configured, placed
with goods that require monitoring and then
downloaded once the goods reach their intended
destination. Other applications may involve stationary
loggers placed in warehouses or to monitor fridges.
Each application requires several steps so you can
deploy your data logger and retrieve the recorded
measurements. You may be able to skip some of the
steps, depending on the way the logger was prepared
when it was delivered to you and how you wish to
analyze the data.

1. Download and install the latest version of LogTag® Analyzer 3.
You can do this from the LogTag Recorders Software Download page.
2. Configure the unit using LogTag® Analyzer.
3. Connect a probe and place the unit in the monitoring location.
4. Start the logger.
Things to do while recording data
5. Clear an active alarm.
6. Review Minimum and Maximum values during the trip, as well as alarm threshold
violations.
7. Reset Minimum and Maximum values.
8. Place a mark in the recorded readings.
9. Stop the logger recording data.
Things to do when you have finished
10. Plug the unit into a USB port.
11. View the PDF report generated by the UTREL-16.

Configuring the UTREL-16 for logging UTREL-16 User Guide 12
Configuring the UTREL-16 for logging
Before a UTREL-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
STOP/Review 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 UTREL-16 logger is delivered to you hibernated (i.e. in a state of low
power consumption), and pressing the STOP/Review shows:
followed by and then

If your logger is unconfigured you must set it up with the parameters required for:
lstarting and recording temperature values
ltriggering alarms
lprinting the PDF

Configuring the UTREL-16 for logging UTREL-16 User Guide 13
This is done using LogTag® Analyzer software, which can also be used for downloading and
analyzing data.
Preparing the logger
lStart the LogTag® Analyzer software.
lRemove the protective cap from the UTREL-16's USB connector, plug it into a USB
socket on your computer and wait for the drivers to be installed4.
You will receive a message that a new USB device has been found, and a generic driver
will be installed5.
Once the driver is installed and the UTREL-16 is ready, it can receive configuration
data. Click LogTag - Configure; LogTag® Analyzer will scan all USB ports and
display the configuration options for connected UTREL-16 units. Although you can
configure many devices at the same time6, it is practical to limit the number of
devices to about 10, using a powered USB hub. It is not possible to configure different
models at the same time.
lClick Configure from the LogTag menu; LogTag® Analyzer will display the
configuration options for connected loggers.
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.
4 You can configure more than one UTREL-16 at the same time, however it is practical to limit the number of units to about 6,
using a powered USB hub.
5 Depending on the factory configuration additional drivers may be installed at this time.
6 You can configure more than one UTREL-16 at the same time, however it is practical to limit the number of units to about 6,
using a powered USB hub.

Configuring the UTREL-16 for logging UTREL-16 User Guide 14
UTREL-16 Start Options
During configuration with LogTag® Analyzer you can decide when the UTREL-16 starts
taking temperature readings:
Push button start
The logger will start taking temperature readings as soon as you have pressed the
START/Mark button (see Starting the Logger on page22).
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 UTREL-16 starts recording as soon as it is unplugged
from the USB port7 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 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 UTREL-16 to start after a delay period, the logger will not immediately
record temperature readings after you have pressed START/Mark, 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.
7 The first pre-start reading is taken one log interval after you unplug the unit from the USB port.

Alarm Configuration Options
LogTag® Analyzer allows up to 6 different alarm trigger conditions for temperature when
configuring a UTREL-16 for recording.
Each alarm trigger condition consists of a threshold temperature value, an activation type
(which can be instant, consecutive or accumulative8) 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 lower
thresholds it is called a lower alarm .
8
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.

Configuring the UTREL-16 for logging UTREL-16 User Guide 17
An alarm event is generated, when either of the entered alarm conditions is triggered. The
threshold values themselves are included in the alarm range, i.e. if an upper alarm
threshold is set at +8.0 °C, a value of 8.0 °C will trigger an alarm, but a value of 7.9 °C will
not.
The UTREL-16 can have up to three upper alarms, and up to three lower alarms.
Figure 3: Alarm ranges and thresholds
Figure 4: Representation in LogTag® Analyzer
You need to observe some basic rules when entering alarm conditions into the
configuration screen in LogTag® Analyzer:
lA primary alarm condition must be entered before the corresponding secondary
alarm condition.
lEqually, primary and secondary alarm conditions must be entered before the
corresponding tertiary alarm condition.
lYou can enter a different number of upper and lower conditions, or only upper, or
only lower conditions, or none at all.
lA secondary upper alarm cannot be entered with a lower threshold value than the
primary upper alarm.

Configuring the UTREL-16 for logging UTREL-16 User Guide 18
lA tertiary upper alarm cannot be entered with a lower threshold value than the
secondary alarm. Threshold values can, however, be equal and combined with
different time-to-activation values. For example, you can enter a primary upper
alarm with an -70.0°C threshold and 10 accumulative readings, plus an alarm with
an -70.0°C threshold and 5 consecutive readings. In this instance the alarm will be
triggered, if either 10 readings in total are above -70.0°C, or 5 consecutive readings
above -70.0°C have occurred.
If an alarm is triggered, you will be able to see this on the PDF, in the software and on the
display.
The section about Reviewing Statistics and Alarms on page26 shows examples of how this
is represented and reviewed on the display.
Finalizing the configuration
Click Configure to upload the configuration data to the UTREL-16.
When the configuration is complete, unplug the UTREL-16 from the USB socket and
replace the protective cap.
If you wish to configure more UTREL-16 units with the same configuration, insert the next
loggers into USB sockets, wait until they are ready for configuration and click Repeat
Configure. Alternatively, you can use the Profile function to configure multiple units with
the same settings.
You can upload the configuration to a UTREL-16 logger as often as required.
