•
The Peak Hold Time is expired after holding the last peak value. In this case, the signal
reverts to the current object temperature reading and restarts the peak holding process
with the given hold time.
•
The current object temperature reading exceeds the last temperature peak value. In
this case, a new peak reading starts with holding the new peak object temperature.

7.2.2. Reset Peak Hold by external Trigger signal
Once the Peak Hold Time is set to 300 seconds, the peak holding process will be activated by
an external trigger input signal (Trigger
high). The post-processed peak hold value stays the
same up to the following happens:
•
The external trigger input signal is pulled down (Trigger
GND). In this case, the signal
reverts to the current object temperature reading and deactivates the peak hold
function as long as the external trigger signal stays pulled to GND.
•
The current temperature reading exceeds the peak hold temperature. In this case, a
new peak reading starts with holding the new peak. No time limit is active for holding
the last peak temperature.
