P047 Outside Count 
 
 
This parameter determines the number of processing cycles, or transducer ‘shots’, 
that any valid echo must be seen outside of the gate before the gate will move and 
allow the new echo to be processed. This will prevent any unwanted update, or 
false readings being given due to the intermittent appearance of echoes from 
devices such as scrapers. 
 
Values  Min = 1 
  Max = 5000 
 
P883 Gate Expand (Available in Stability Menu under 1997) 
 
 
This parameter is closely associated with the Outside Count as part of the 
Damping parameters designed to make the reading more stable. When the Outside 
Count has expired and the Gate is moving towards a new target then it expands at 
a rate of 0.1m after every cycle. 
Values  Min = 0 
  Max = 99.99
