Stability Parameters
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 = 10m/min (32.8084 ft/min).
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 = 10m/min (32.8084 ft/min).
Rate
P874 Rate Update
This parameter determines the way in which the rate is calculated. If set to
continuous (P874=0), then the rate is calculated and displayed
continuously, i.e. any change seen from shot to shot is calculated and
displayed, but if set to use values P874=1(Default) then the values set in
P875 and P876 are used to calculate and display the rate.
P875 Rate Time
This parameter is the period (in seconds) over which the material level rate
of change is averaged before the Rate Value (P877) is updated. If the Rate
Distance (P876) is exceeded before the Rate Time (P875) has expired, then
the Rate Value (P877) will be updated immediately. Default = 60sec.
P876 Rate Distance
This parameter is the rate Measurement Units (P104) over which the
material level must change before the Rate Value (P877) is updated. If the
Rate Time (P875) expires before the Rate Distance (P876) is exceeded,
then the Rate Value (P877) will be updated immediately. Default = 0.05m
P877 Rate Value
This parameter displays the current rate of change of material level, in
Measurement Units (P104) per minute. It is read only.
