#### Check Distance

The Check Distance box lets you enter the distance in either inches or millimeters (depending on the measurement system used for the part) 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.

The Edit window command line for this option reads:
CHECK/distance,percentage

Percentage Movement During Find Hole Operations

When defining the check distance for a Find Hole operation, you can tell PC-DMIS to move by a percentage of the check distance.

To do this:

1. Access the Edit window and place it in Command mode.

2. Click on the CHECK command in the Edit window.

3. Press the TAB key to move to the second number.

4. Type a new percentage value. The default value is 1 which means 100% of the check distance. Thus .1=10%, .2=20%, .3=30% etc.

For example, in the following code:
CHECK/20,.3, the .3 value represents 30% of the total check distance of twenty units.
