TRED30-16R Start Options
During configuration with LogTag
the TRED30-16R starts taking temperature readings.
... via Push button start: The recorder will start taking
l
temperature readings after you have gone through a specific start
sequence of pressing and releasing the
button (see Starting the Recorder
... via Date/Time start : The recorder will start taking
l
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
If you configure the TRED30-16R to start after a delay period, the
l
recorder will not immediately record temperature readings after
you have pressed
START
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 TRED30-16R 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 ( ).

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.
The alarm triggering structure in the recorder supports many
different alarm trigger configurations.
For example, a possible alarm trigger configuration could be:
Upper alarm is triggered when the temperature is 10°C or above
l
for an accumulative time of 10 hours.
Lower alarm is triggered when the temperature is -0.5°C or below
l
continuously for 1 hour.
All alarm trigger conditions are configured using LogTag

alarm processing starts again. Accumulative or consecutive alarms
