#### Check Distance

CHECK/nnn.nnnn,p.pp

This command determines the distance in inches or millimeters (depending on the system of measurement that was initially set up for the particular part program ) past the theoretical hit location that the machine will continue to search for the surface of the part until it determines the surface is not there.

nnn.nnnn:
The check distance

p.pp:
The percentage of the total check distance that PC-DMIS will move when performing a Find Hole operation. The default value is 1 which means 100% of the check distance. Thus .1=10%, .2=20%, .3=30% etc. This only functions with Find Hole operations.

- If PC-DMIS finds a surface within the specified check distance, it takes a hit.

- If no surface is found PC-DMIS displays an error message that it has encountered an unexpected end of move.

- Example: If .3 inches is entered as the check distance, PC-DMIS will move .3 inches past the theoretical surface, searching for a surface on which to make the hit.

  See "Check Distance" in the "Setting your Preferences" section for additional information.
