The purpose of ZEISS CMM probe calibration is to correct the diameter of the ruby ball from the measuring rod (tip), to correct the measuring point probe and to derive the position relationship between the different probe positions. Any errors generated during probe correction are added to the measurement. So in this link, it is necessary to ensure that it is correct and accurate.

ZEISS** three precision instrument tips to pay attention to the following points:
1. Keep the standard ball and measuring rod clean.
2. Ensure that the probe seat, probe, measuring rod and standard ball are fixed firmly.
3. Enter the correct rod length and standard ball diameter.
4. Judge the accuracy of the correction according to the shape error and the diameter and repeatability of the corrected gem ball.
The diameter of the corrected gem ball will be different depending on the length of the extension).
When different probe positions are to be used, the calibration accuracy is checked by measuring the coordinates of the center point of the standard sphere after all probe positions have been corrected.
The probe file saved after the calibration of the ZEISS CMM probe can be recalled and used under the premise that the probe and stem are not moving. However, if the measurement accuracy is relatively high, it is recommended to recalibrate the probe.
