Description
Set limit for zero-point adjust‐
ment "Standard Deviation" val‐
ue.
Standard deviation during auto
zero-point adjustment.
Set limit for "Zero Offset".
Zero-point offset compensates
for sensor variation due to proc‐
ess conditions.
Enter agreed zero-point offset
value.
Set the process value filter for
aerated flow. Auto means that
filtering starts automatically
when measuring aerated flow.
Set alarm limit in percent of ac‐
cepted bad measurements.
Set warning limit in percent of
accepted bad measurements.
Set the time period over which
the actual percentage of unsta‐
ble measurements is calculated
Set the hysteresis value. The fil‐
ter is active when the hysteresis
value is exceeded.
Set the filtering time. The filter‐
ing time is reset each time hys‐
teresis band is exceeded.
Set the number of times to re‐
peat the same filter. Increasing
the number will increase the
damping.
