Introduction UTREL30-WiFi User Guide 8
Introduction
The LogTag® UTREL30-WiFi low-temperature data logger automatically uploads real-time
temperature data1 to your LogTag® Online cloud account via your existing wireless
network. It features a large, easy-to-read display, along with many familiar attributes
known from the LogTag® family of data loggers. These include non-volatile memory for
up to 16,129 temperature readings and a statistical memory, storing maximum and
minimum reading as well as alarm duration for each of the last 30 days.
During recording the display shows
lthe current temperature (of the most recent reading);
lthe alarm status, current time and battery status;
lan alarm trigger summary of up to the last 30 days (today and 29 days previous); and
lthe wireless and cloud connection states.
At set intervals the UTREL30-WiFi uploads the data to your LogTag® Online cloud
account, where it can be viewed, analyzed and shared with others, or downloaded for
further analysis.
Logged temperature data can also be viewed on any PC by plugging the unit into a
computer’s USB port via a micro-USB cable, for example if a Wireless Network is
unavailable. This allows viewing of a PDF file, which can be accessed using PDF software
such as Acrobat Reader, or downloading the data to the free companion software LogTag®
Analyzer, where you can display data in chart, list or summary formats.

Configuring the UTREL30-WiFi for logging
Before a UTREL30-WiFi 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. Also, your reseller may have already
configured the device to be connected to your wireless network.
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-WiFi for first use UTREL30-WiFi User Guide 17
The logger is unconfigured
An unconfigured UTREL30-WiFi 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;
lconnecting to the local WiFi network;
lconnecting to your LogTag®Online cloud account; and
ltriggering alarms.
This is done using LogTag® Analyzer software, which can also be used for downloading and
analyzing data. LogTag® Analyzer includes the LogTag®Online Connection Wizard, which
will allow you to set wireless and network settings and register the UTREL30-WiFi against
your LogTag® Online account.
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.
1 You can configure more than one UTREL30-WiFi 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-WiFi for first use UTREL30-WiFi User Guide 18
lFrom the menu click LogTag - Configure; LogTag® Analyzer will display the
configuration options for connected loggers.
The logger will be configured in LogTag®Online
LogTag®Online can transfer configuration settings containing recording and alarm
parameters to the logger, and automatically start recording temperature data once the
transfer has completed. To do this, following steps are required:
1. Configure the UTREL30-WiFi's wireless network settings using the LogTag®Online
Connection Wizard.
2. Register the device in LogTag®Online.
3. Attach the UTREL30-WiFi to a location. During the attachment process, select one of
the pre-defined Logger Configuration Profiles. Each profile contains
lthe log interval;
lalarm settings for all alarms; and
loptionally, a start delay.
Once the settings have been applied, you can view them directly in LogTag®Online
for each device. Please refer to the LogTag® Online User Guide for more information.
Please note: This method of configuration sets only a minimal number of pre-
defined parameters to enable logging and transferring real-time data. If you wish
to control the appearance of the PDF file, set advanced options or specify custom
logging parameters please configure the unit using LogTag® Analyzer.

Preparing a UTREL30-WiFi for first use UTREL30-WiFi User Guide 19
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.

Preparing a UTREL30-WiFi for first use UTREL30-WiFi User Guide 20
UTREL30-WiFi Start Options
During configuration with LogTag® Analyzer you can decide when the UTREL30-WiFi
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46).
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-WiFi 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. Pre-start readings are also
not uploaded to LogTag®Online. 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-WiFi 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.
2 The first pre-start reading is taken one log interval after you unplug the unit from the USB port.
