Calibration procedure |
Max min calibration |
More normal calibration (single gauge calibration) |
Repeatability and measurement uncertainty |
Relatively high |
Relatively low |
reliability |
Depends on the accuracy of the amplifier and environmental conditions |
Depends on probe quality and environmental conditions |
Automation item selection |
The relative fit gap is small, and the non-standard measuring head needs to be chamfered accordingly and equipped with a floating machine |
The relative fit gap is large, the application is relatively easy, and the accuracy of the mechanical motion mechanism is relatively low |
