time is 0,1s; on the models 1M, 2M and 3M 1ms (0,001s). On these models
values below 0,1s can be increased/ decreased only by values of the power
series of 2 (0,002, 0,004, 0,008, 0,016, 0,032, ...).
In this mode the sensor is waiting for descending signals. If the signal
descends the algorithm maintains the previous signal peak for the
specified Hold time.
The minimum adjustable hold time is 1 ms (0,001 s).
After the hold time the signal will drop down to the second highest value
or will descend by 1/8 of the difference between the previous peak and
the minimum value during the hold time. This value will be held again for
the specified time. After this the signal will drop down with slow time
constant and will follow the current process temperature. ► Signal

Therefore, if periodic events will be measured (bottles on a conveyor e.g.)
this peak hold function avoids a drop down of the signal to the conveyor
temperature in-between 2 events.
In this mode the sensor waits for ascending signals. If the signal ascends
the algorithm maintains the previous signal valley for the specified Hold
time. The definition of the algorithm is according to the peak hold algorithm
(inverted).
In this mode the sensor waits for local peak values. Peak values which are
lower than their predecessors will only be taken over if the temperature has
fallen below the Threshold value beforehand. If Hysteresis is activated a
