7.4.2.3 Peak with capture
This calculation determines the minimum, maximum or oscillation bandwidth of a sig-
nal. You can also have the value of another channel (Hold Channel) determined when an
extreme value is reached (output signal Captured Value). You can tell by the falling edge
of the peak flag (about 1 ms after detection of a new peak value) that a new peak value
has been found. As long as the measured value continuously rises (in case of maxi-
mum) or falls (in case of minimum) the peak flag is High (1).
Select the desired function and if necessary create a digital input to reset the value
(level-controlled, in case of High (1), Reset by). Set Reset on to Low level to reset as long
as a Low signal (0) is active.

Abb. 45: Peak value with capture (example)
You can use the Reset by input to capture no new (peak) value at specific times, leaving
the current one instead. This is equivalent to temporarily deactivating the memory func-
tion. The capture takes place level-controlled at High (1), unless you are using Hold on:
Low level, capture takes place as long as a Low signal (0) is active.
If the source signal Input is invalid, no analysis is carried out. If the signal of the Hold
Channel is invalid at the time of a peak value, the value is stored, but is marked as
invalid.
