- 1). Retract the screw gauge slightly more the object you are measuring.
- 2). Slip the screw gauge into or around the object you are measuring, depending on the type of gauge you are using.
- 3). Advance the screw gauge just until the object will not slip. Do not overtighten.
- 4). Lock the gauge in place. Most micrometers will have either a thumb wheel or thumb lever locking mechanism on the handle.
- 5). Remove the micrometer and read the measurement.
