 P1-882, P2-882 Process Filter 
This parameter determines the number of ‘cycles’ that will be taken before a 
change in level is processed and the display updated. 
level will be updated every cycle  
level will be updated every 8 cycles 
level will be updated every 16 cycles 
 
P884 Peak Percentage 
When P1-102, P2-102 = 2 (Solids), this parameter can be used to determine 
the point at which the the measurement is taken, within the established gate 
of the selected echo, in order to compensate for any error that maybe caused 
by    “angles  of  repose”  presented  by  the  way  the  material  settles.  Please 
consult Pulsar for further information and assistance on changing the value 
of this parameter. 
Echo Processing Parameters 
Transducer 1 Status 
P1  
P1-900 Transducer 1 Status 
This  parameter shows  the current  state  of the transducer  on  Point 1. The 
value means the following. 
Transducer working correctly. 
Transducer is not being used (mA input is being 
used instead, so P101=1) 
Indicates  that  the  power  and  signal  lines  on  the 
transducer terminals are crossed over, or the signal 
line is shorted to earth. 
No transducer is detected. 
 
P1-901 Echo Confidence1 
This parameter displays the most recent echo confidence from the transducer 
on  Point  1.  It  is  useful  to  help  find  the  best  mounting  location  for  the 
transducer, where you should aim to get the highest figure. It is a percentage 
of confidence that the echo reporting the level is the correct one.
