UTRED30-WiFi Start Options
During configuration with LogTag® Analyzer you can decide when the UTRED30-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 page46).
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 UTRED30-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 UTRED30-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.
