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.
