SET FILTER Time
Select SCALE 0 mA/
4 mA (low endpoint)
A time constant (in seconds) can be set to filter or “smooth
out” the output signal. A minimum value of “0 seconds” has
no smoothing effect. A maximum value of “60 seconds” pro-
vides maximum smoothing. Deciding what output filter time
to use is a compromise. The higher the filter time, the longer
the output signal response time will be to a change in the
measured value.
