Specify the direction of compensation for the probe.
When you probe a part manually, PowerInspect provides two methods for determining the direction of probe compensation:
- Automatic probe compensation — calculates the direction of compensation from the orientation of the probe when the first point is taken. This method is used by default.
- Pre-touch point probe compensation — calculates the direction of compensation by taking a fresh-air point before taking the first measurement point.
Automatic probe-compensation
When you probe a part manually, probe compensation is automatically applied in the direction of the vector running from the stylus tip to the last knuckle joint of the arm.
To use automatic compensation, you must point the probe at the surface being measured when you take a point. The following diagrams show how to position the probe:
- Correct orientation of the probe relative to the surface.
- Incorrect orientation of the probe relative to the surface.
- When probing inside features, the probe must point toward the surface of the hole as near normal to the surface of the feature as possible. For example:
