1. Change the Set Headlength Unit on the Control Box and or the ControlTechManager
Qualifier Menu to inches.
2. When in Control Mode executing Parameters from the PC ControlTechManager or
Control Box when using interchangeable head style instruments with a Snap-on “A”
suffix torque adapters, the Parameter Headlength field is shown as 0 (zero). The Control
Box interprets 0 (zero) as the default calibrated length on J, Y, X and Z shank
