Introduction UTRED30-16User Guide 5
Introduction
The LogTag® UTRED30-16 temperature logger features a data logging memory storing up to 16129
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 current temperature (of the most recent reading)
… the alarm status (within or outside the acceptance range)
… an alarm trigger summary of up to 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 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 PDF software such as Acrobat
Reader. The UTRED30-16 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.
Features
The UTRED30-16 temperature logger features a large display and USB connectivity with a familiar LogTag®
feel.

Configuring the UTRED30-16 for logging
Before a UTRED30-16 logger can be used, it must be configured 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.
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.
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.
UTRED30-16 Start Options
During configuration with LogTag® Analyzer you can decide when the UTRED30-16 starts taking
temperature readings:
Push button start
Date/Time start
The logger will start taking temperature readings at the date and time you specify (local time).

When you choose the push button start option, you can select to record Pre-start readings or Begin
recording after a delay:
lIf you select pre-start readings, the UTRED30-16 starts recording as soon as it is 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, and no PDF file will be generated. 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.
lIf you configure the UTRED30-16 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. It will, however, continue to take pre-start
readings, if enabled.
You cannot combine a date/time start with pre-start readings or the start delay function.
Alarm Configuration Options
The UTRED30-16 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 ( ). 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 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 10.0°C or above for an accumulative time of 10
hours.
lthe lower alarm is triggered when the temperature is -0.5°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24) or the unit is reconfigured. The day alarm marker remains shown until midnight,
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

Preparing a UTRED30-16 for first use UTRED30-16User Guide 12
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.

Powering the UTRED30-16 UTRED30-16User Guide 17
Powering the UTRED30-16
The UTRED30-16 can be supplied from one of two power sources:
lvia two AAA batteries
The batteries have a life span of approx. 6 to 12 months, depending on the quality of the battery, log
interval, frequency of reviewing data on the display and how often an alarm sounds.
The batteries inside the unit will not be charged when external power is supplied.
A 4-bar battery indicator shows an approximate remaining battery capacity. If the batteries are full,
this symbol will be shown:
When the batteries are empty, this symbol will be shown, and the batteries require replacement.
Please always replace both batteries with fresh ones at the same time. Replacing only one
of the batteries with a partially charged battery will drain the internal backup battery.
It is possible to use rechargeable AAA cells, however, please note that due to the different
voltage the battery indicator will not show the correct remaining percentage, and the internal
backup battery may drain faster. Rechargeable cells will deplete faster than Alkaline or
Lithium batteries.
lvia a commercially available 5V USB power supply (5W).
When supplied externally, the power symbol shows on the display.
Supplying the unit with external power allows you to use the internal AAA batteries as a backup
should external power be unavailable.
When you remove the external USB power the display briefly turns off.
Some low-quality USB power supplies are unable to deliver sufficiently stable power to the
UTRED30-16. Please use a power supply from a reputable source that carries a UL or CE
marking.
If the logger detects an unstable power source, the power symbol will flash and the
buzzer will sound.
In this case, the logger will not be powered by the external supply, but remain powered by
the AAA batteries instead. Please remove the supply and replace it with one of better
quality.

Audible Alarm UTRED30-16User Guide 19
Audible Alarm
The UTRED30-16 is fitted with a buzzer. You can choose to activate the buzzer when an alarm event has
been registered 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.
The alarm will sound once every four seconds for the first 24 hours. To preserve battery life, the interval at
which the alarm sounds will increase to 8 seconds when the clock passes midnight after the initial 24 hour
period (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 again, the interval changes to 12
seconds. It will remain at 12 seconds 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 Alarm Re-triggering on page12
The buzzer will temporarily turn off when you are reviewing data.

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. Please note, however, that the PDF's time zone has to be set at configuration and cannot
be changed after the logger has been downloaded.
