#### Calibration Mode area

The Calibration Mode area contains options allowing you to switch between the Default Mode and the User Defined options, as described below.

Default Mode

If the Default Mode option is selected, PC-DMIS will take the number of indicated hits around the spherical tool at either 10 or 15 degrees from the equator, plus one additional hit normal to the probe, 90 degrees from the equator.

Sample Spherical Tool | 1 - Normal to Probe 2 - Equator 3 - Shaft

Taking the hits at either 10 or 15 degrees prevents the shank of the probe from hitting the calibration sphere when the shank diameter is almost as large as the probe's tip diameter.

If your tip's diameter is less than 1 mm, PC-DMIS takes the hits around the sphere at 15 degrees.

If your tip's diameter is greater than 1 mm, PC-DMIS takes the hits around the sphere at 10 degrees.

User Defined Mode

If the User Defined option is selected, PC-DMIS will allow you to access the levels and angles boxes. PC-DMIS will measure the probe based on the number of levels that are entered and the starting and ending angles that are selected. The location of the level is based on the angles that are set. 0° is located at the equator of the probe. 90° is normal to the probe. Only one hit will be taken when measuring normal to the probe.

Number of Levels

The Number of Levels box determines the number of levels that will be used in the calibration process. PC-DMIS will divide the number of hits by the number of levels to determine how many hits will be taken at each level.

Start and End Angles

The Start Angle and End Angle boxes control the location of the first and last level. Any additional levels will be located equally between these two levels.

- A starting angle of 0° is located at the equator of the sphere (relative to the probe).

- An ending angle of 90° is located at the top of the sphere, normal to the probe.
