#### Compensation Options area

Probe Compensation Active (On)

The Probe Compensation Active (On) check box allows PC-DMIS to compensate for the probe radius. If marked, and you click OK, this inserts a PROBECOM/ON command into the Edit window. PC-DMIS will compensate for the probe radius on each feature it measures. If cleared, then the command is set to PROBECOM/OFF in the Edit window. If you're using a Portable device, you can use the Portable toolbar to toggle this on or off as well.

Polar Vector Compensation

The Polar Vector Compensation drop-down list allows the measurement of Vector and Surface points to always be compensated along a Polar vector. The following options are available:

- OFF - Vector and Surface points behave normally.

- XYPL - Vector compensations for each Vector and Surface point will be 2D in the XY plane along a vector from the point to the current origin.

- YZPL - Vector compensations for each Vector and Surface point will be 2D in the YZ plane along a vector from the point to the current origin.

- ZXPL - Vector compensations for each Vector and Surface point will be 2D in the ZX plane along a vector from the point to the current origin.

- 3D - Causes a polar vector compensation along a 3D vector from the point to the current origin.

The Edit window command lines for these options read:
POLARVECTORCOMP/ OFF
POLARVECTORCOMP/ XYPL
POLARVECTORCOMP/ YZPL
POLARVECTORCOMP/ ZXPL
POLARVECTORCOMP/ 3D
