Peak Picking
This type monitors the input and determines a “peak” value reached during the specified time interval (in
minutes). The peak can be chosen to be a maximum, minimum, average, or standard deviation. At the
end of the time interval, the output CVn OV steps to the value of the peak and holds this value until the
end of the next time interval. If the Reset Input turns ON(1), the output is held and the time interval
restarts.
