The Clamping Value only works with the Leitz controller and the Leitz brand TTP. This value tells the controller how firmly to hold the probe on a Leitz CMM.
Depending on the weight of the probe tips, you may need to increase or decrease the clamping value.
For a large tip weight, you may need to increase the clamping value.
For a small tip weight, you may need to decrease the clamping value.
