Stability
Damping
Damping is used to damp the display, 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)
Filters
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 (in excess
of 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 “angl es of
repose” presented by the way the material settles. Please consult Pulsar, for
further information and assistance on changing the value of this parameter.

Important Notice
Parameters 926, 927 and 928 do not affect how the unit performs, but
details contained in them may be required, by Pulsar, when making
technical enquiries.
