#### 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" chapter for additional information.
