Caliper Calibration Procedure – How to Calibrate a Caliper

In past Mitutoyo Metrology Training Lab episodes, we have defined the concept of calibration, discussed the purpose of calibration, and introduced important aspects of what makes a good calibration method. In this episode, we will apply all those ideas to the calibration method for a caliper.

Calibration is a search for errors and we want to develop a calibration method that efficiently hunts down and finds any potential errors in the measuring instrument. So how do we best do that for a caliper? Well, there is a nice American National Standard for digital, dial, and vernier calipers, called ASME B89.1.14, and the calibration method we’ll be discussing is based on that standard.
