Total and Grand Total Count Direction (Count)
By default, the batch total and grand total count up during batch
processes. Count parameter allows this to change. When set to count
down, the batch total will count down from the preset to 0. When set to
count down, the grand total will count down from a set value up to
999,999.
Noise Filter (filter)
The noise filter is available for unusually noisy signals that cause an un-
stable process variable display. The noise filter averages the input signal
over a certain period. The filter level determines the length of time over
which the signal is averaged. The filter level can be set between 2 and
199. The higher the filter level, the longer the averaging time and so the
longer it takes the display to settle to its final value. Setting the filter level
to zero disables the filter function.
Noise Filter Bypass (bypass)
The noise filter bypass changes the behavior of the controller so that
small variations in the signal are filtered out but large abrupt changes in
the input signal are displayed immediately. The bypass value determines
the minimum amount of signal change to be displayed immediately. All
signal changes smaller than the bypass value are filtered or averaged by
the controller. The noise filter bypass may be set between 0.1 and 99.9%
of full scale.
