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 
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 
Indicator 
P872 Fill Indicator 
This parameter determines the rate at which the LCD fill indicator activates. 
Default = 10m/min 
P873 Empty Indicator 
This  parameter  determines  the  rate  at  which  the  LCD  empty  indicator 
activates. Default = 10m/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.
