UTRED30-WiFi Start Options
During configuration with LogTag
temperature readings:
Push button start
The logger will start taking temperature readings as soon as you have pressed the
button (see Starting the Logger on
When you choose the push button start option, you can select to record
recording after a delay:
If you select pre-start

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
If you configure the UTRED30-WiFi to start after a delay period, the logger will not immediately record
l
temperature readings after you have pressed
instead, and record readings only after the timer has ended. The value for the timer is set during
configuration. If enabled, it will continue to take pre-start readings.
Date/Time start
The logger will start taking temperature readings at the date and time you specify (local time). You cannot
combine a date/time start with pre-start readings or the start delay function.
Alarm Configuration Options
The UTRED30-WiFi 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.
If an alarm is triggered, a notification is also sent immediately to your LogTag
Each alarm trigger condition consists of a threshold temperature value, an activation type (which can be
instant, consecutive or accumulative
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:

Instant = one temperature reading is above (below) the threshold

Consecutive = temperature readings are above (below) the threshold for the time defined in the activation delay without interruption

Accumulative = temperature readings are above (below) the threshold for the total time defined in the activation delay time, but may not
