#### Use Partial Calibration check box

When using the Renishaw scan-based method to calibrate a Renishaw analog probe (such as the SP25, SP600, or SP80), the first time it's calibrated using the Scan method must be the full calibration that runs the whole series of scans. After this full calibration, you can choose a more simplified calibration if desired.

- Full calibration calculates all the analog probing coefficients in addition to the tip offset and tip size.

- Partial (simplified) calibration works just like a non-analog probe calibration: it consists of discrete hits (no scans) and only calculates the tip offset and tip size; the analog probing coefficients remain unchanged.

To perform the simplified calibration,

1. Access the Probe Utilities dialog box.

2. Load a Renishaw analog probe from the Probe File list.

3. Select the Use Partial Calibration check box. This remains disabled for probes that do not apply.

4. Select one or more already calibrated probe tips from Active Tips List.

5. Click the Measure button. The Measure dialog box appears.

6. Make changes as needed on the Measure dialog box. If you define any named parameter sets PC-DMIS will store the state of the Use Partial Calibration check box in the set for future use.

7. Click Measure. Follow any on-screen prompts. PC-DMIS will perform the simplified calibration.

Note: A registry entry in the ProbeCal section called ProbeUsePartialCalibration stores the default for whether or not this check box is selected when you define a new probe file.
