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.
Rounding Feature (
round
)
The rounding feature is used to give the user a
steadier display with fluctuating signals. Rounding is
used in addition to the filter function.
Rounding causes the display to round to the nearest
value according to the rounding selected. See
examples below:
