Configuring the UTRED-16 for logging UTRED-16 User Guide 10
Configuring the UTRED-16 for logging
Before a UTRED-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 UTRED-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 UTRED-16 for logging UTRED-16 User Guide 11
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 and insert the UTRED-16 into a USB port.
You will receive a message that a new USB device has been found, and a generic driver
will be installed3.
Once the driver is installed and the UTRED-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 UTRED-16‘s. Although you can
configure many devices at the same time4, 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.
lRemove the protective cap from the logger's USB connector, plug it into a USB
socket on your computer and wait for the drivers to be installed5.
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.
3 Depending on the factory configuration additional drivers may be installed at this time.
4 You can configure more than one UTRED-16 at the same time, however it is practical to limit the number of units to about 6,
using a powered USB hub.
5 You can configure more than one UTRED-16 at the same time, however it is practical to limit the number of units to about 6,
using a powered USB hub.

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.
UTRED-16 Start Options
During configuration with LogTag® Analyzer you can decide when the UTRED-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20).
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 UTRED-16 starts recording as soon as it is unplugged
from the USB port6 and will continue to do so until you start the unit. 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 UTRED-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 specified during
configuration (local time). You cannot combine a date/time start with pre-start readings or
the start delay function.
6 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 UTRED-16 for recording, depending on the model.
Each alarm trigger condition consists of a threshold temperature value, an activation type
(which can be instant, consecutive or accumulative) 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 .
An alarm event is generated, when either of the entered alarm conditions is triggered.
The UTRED-16 can have up to three upper alarms, and up to three lower alarms.

Configuring the UTRED-16 for logging UTRED-16 User Guide 15
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.
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 8°C threshold and 10 accumulative readings, plus an alarm with 8°C
threshold and 5 consecutive readings. In this instance the alarm will be triggered, if
either 10 readings in total are above 8°C, or 5 consecutive readings above 8°C have
occurred.

Configuring the UTRED-16 for logging UTRED-16 User Guide 16
Any alarm condition that is activated will be shown on the PDF, in the software and on the
display.
The section about Reviewing Alarms on page24 shows examples of how this is
represented and reviewed on the display.
Finalizing the configuration
Click Configure to upload the configuration data to the UTRED-16.
When the configuration is complete, unplug the UTRED-16 from the USB socket and
replace the protective cap.
If you wish to configure more UTRED-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 UTRED-16 logger as often as required.

Adding the Probe
Before the UTRED-16 can record temperature data you will
need to connect an external probe.
The UTRED-16 accepts any ST100 probe. Plug the sensor
into the socket located on the side of the device, as shown.
Starting the Logger
Before you carry out the following start procedure, please ensure you have plugged
the external probe firmly into the socket on the side of the logger.
Push button start, quickstart enabled
Press and hold the START/Mark button until READY disappears and the
symbolS T ART I N G is shown. The UTRED-16 now records temperature data. This start
option works very similar to other LogTag® LED products.
Push button start, quickstart disabled
Press and hold the START/Mark button. READY immediately disappears, and the
symbol blinks for 4 seconds. The symbol then shows permanently for 2 seconds. If you
release the button during this time, the logger starts taking temperature readings. The
symbol remains shown. If the button is released earlier than 4 seconds or later than
6 seconds, the display shows READY again, and the logger does not start.
Push Button Start with Start Delay
If the logger was configured for push button start with a start delay (regardless of
quickstart settings), the word DELAY is shown instead ofthe symbol, once you have
started the logger.
The delay time is shown in hours and minutes, if it is less than 24:00 hours, and the word
