You can use the Check Calibration Limits command to check for probe calibration errors and raise alerts during execution. You can combine this command with the On Error command with an error type of "Calibration Outside Limits" to control the execution.
The table shows the descriptions of the errors checked and their bits:
| Error Description | Error Bit |
| Calibration Validity | 1 |
| Calibration Interval | 2 |
| Standard Deviation | 4 |
| Tip Diameter | 8 |
The Probe Setup dialog box provides an ability to set the limits for the above errors.
To open the Probe Setup dialog box, from the Probe Utilities dialog box (Insert | Hardware Definition | Probe), click the Setup button.
