Stability Parameters 
Damping 
P1 or P2 
Damping  is  used  to  damp  the  display,  to  enable  it  to  keep  up  with  the 
process but ignore minor surface fluctuations. 
P1-870, P2-870 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 = 32.8084 feet/min 
P1-871, P2-871 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 = 32.8084 feet/min 
Indicator 
P1 or P2 
P1-872, P2-872 Fill Indicator 
This parameter determines the rate at which the LCD fill indicator activates. 
Default = 32.8084 feet/min 
P1-873, P1-873 Empty Indicator 
This  parameter  determines  the  rate  at  which  the  LCD  empty  indicator 
activates. Default = 32.8084 feet/min 
Rate 
P1 or P2 
P1-874, P2-874 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.
