Is a digital micrometer necessary for measuring rotor depth or scoring?

A digital micrometer is not strictly necessary for measuring rotor depth or scoring because an analog micrometer can provide the same level of precision needed for these measurements. Both types of micrometers are designed to provide accurate measurements; the main difference between them lies in how measurements are read.

Analog micrometers can require a bit more interpretation, as the user must read the scale manually, while digital micrometers display the reading directly, making it easier and quicker to obtain the measurement. However, if a technician is skilled in using an analog micrometer and familiar with taking precise measurements, it can effectively serve the same purpose.

In practical applications, especially within a shop setting, using an analog micrometer can be completely sufficient for ensuring that rotors meet safety and performance standards. Thus, choosing to use an analog device does not compromise the quality of measurement when addressing rotor depth or scoring.
