### Pulled Hits Method

For a portable arm device, you would follow this procedure to measure a point using a "pulled hit" for probe compensation:

1. Place the probe on the surface at the point location (1). The probe shaft vector does not matter when performing a "pulled hit".

Either one of these examples will work for pulled hits

2. Press and hold the hit button long enough to get a pulled hit, but not so long that PC-DMIS starts scanning the part. To change the length of time to distinguish between “pulled hit” or “start scanning”, you can modify the DelayToStartSendingScanPointsToManualHit registry entry using the PC-DMIS Settings Editor. See Modifying Registry Entries: Introduction.

3. Move the tip in the direction of the vector (2) you want to send to PC-DMIS, away from the hit location. You must move it a distance equal to or greater than the defined vector distance (3). To define the minimum distance from the hit that you must move the probe for a pulled hit to be accepted, you can modify the VectorToIMM registry entry using the PC-DMIS Settings Editor. See Modifying Registry Entries: Introduction.

4. Release the button. You will hear a different lower audible tone. Notice the measured point has been added to the Edit Window.

5. With the point high-lighted, press F9 to open the Measured Point dialog box. Verify that the vector is following the PULL direction not the shaft direction.

Note: For Auto Features, the last hit vector determines the compensation direction. For Measured Features, the first hit vector determines the compensation direction.
