7.3.2 Peak Hold
With Peak Hold, the respective last peak value is held until the next reset will occur. There are the
following possibilities for a reset.
7.3.2.1 Reset
 Reset by Time: The peak will be held for a certain hold time. Once the hold time is exceeded
the output signal, tracks and output the actual object temperature and the algorithm will start
over again. This function is set on the control panel, the software or by means of the
programming command <P>.

 Reset by Trigger: A logical low signal for the trigger will reset the peak hold function. As long
as the input is kept at logical low level the actual object temperatures will be transferred toward
the output. At the next logical high level, the hold function will be restarted.
To activate the reset by trigger function, the Peak Hold must be set to 300.0 either through the
control panel, or DataTemp Multidrop Software, or the programming commands <P>. For
wiring the external trigger, see section 7.4.3.1 Trigger, page 44.
