P048 Gate Lock 
 
 
This parameter should only be used under the direction of Pulsar. If ‘ON’ the gate 
will remain ‘locked’ on the selected echo, regardless of the presence of any other 
sized echo outside the gate, unless the selected echo falls below the value of the 
loss limit. 
Options  0 = No 
  1 = Yes 
 
P049 Scale First 
  
 
When P067 = 1 Best, this parameter determines the amount of weighting applied 
to the first valid echo above the Loss Limits, before comparing it to other 
competing echoes, the resulting largest echo will then be processed as the correct 
echo.  
Values  Min = -100% 
  Max = 100%
