CALIBRATE HOLD OFF, discrete
parameter, 0, 1
When ON(1), no samples are taken and the output is held.
If calibrate hold is set ON, the function block stops acquiring
samples; however, the averaging will continue to update for the
remainder of the average period, after which, the output value will
hold.
If calibrate hold is set ON longer than the average period, the
display will alternate between the last output value and
*****(indicating the current value is no longer valid).
If calibrate hold is set OFF and the CEM Rolling Average is not
reset, the CEM Rolling Average will continue to update every frame
period from the last value. If the CEM Rolling Average is reset, the
average value is set to zero and the displayed value will not update
until the Average period has transpired. The average value will
update every frame period.
