Noise Filter (filter)
The noise filter is available for unusually noisy signals that cause an
unstable 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 meter 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 meter. The noise filter bypass may be set between 0.1 and
99.9% of full scale.
