P046 Persist Count (Direct Access Only) 
 
 
This parameter determines the number of processed echoes the unit will need to 
see moving in the same direction before the display reading is updated. This is to 
help prevent the displayed reading from fluctuating whilst inside the gate. Sludge 
echoes are constantly changing shape and in order to prevent the reading from 
‘hunting’, the echo has to move in the same direction for 5 counts in order for it to 
be seen as a trend and update the reading. 
 
Values  Min = 1 
  Max = 1000
