Shank Qual check box
Select the Shank Qual check box if you are using a shank tip to take edge hits. Use this check box to qualify the shank of the probe. If you select this option, you can manipulate the Num Shank Hits box and Shank Offset box.
Be aware that if you are using a shank probe, you only need to do a shank calibration if you'll be taking edge hits.
