Stability
Damping
Damping is used to damp the reading displayed, to enable it to keep up
with the process but ignore minor surface fluctuations.
P870 Fill Damping
This parameter determines the maximum rate at which the unit will respond
to an increase in level. It should be set slightly higher than the maximum
vessel fill rate.
Default = 10.000 metres/minute (32.81 feet/minute)
P871 Empty Damping
This parameter determines the maximum rate at which the unit will respond
to a decrease in level. It should be set slightly higher than the maximum
vessel empty rate.
Default = 10.000 metres/minute (32.81 feet/minute)

P881 Fixed Distance
This parameter determines the width of gate to be used in tracking an echo
and under normal circumstances will not require changing, but it can be
increased in the cases where the surface is moving extremely fast (more than
10m/min) to ensure smooth processing of the changing level.
P884 Peak Percentage
When P102 = 2 (Solids), this parameter can be used to determine the point
at which the measurement is taken, within the established gate of the
selected echo, to compensate for any error that maybe caused by “angles of
repose” presented by the way the material settles.
Please consult Pulsar
Measurement for further information and assistance on changing the value
of this parameter.
