Screw gauge measurement procedure

WebbThe general procedure is as follows: Step 1: Smooth the wire first before attempting to measure it. This also applies to metal sheets. Step 2: Using the two “teeth” of the frame, grasp the wire, and tighten the grip on the wire by adjusting the spindle. Adjust it until the wire is held tightly. Webb1 maj 2024 · The specification includes additional details about the face of the contacts that specify parallelism of 4.0µ” (0.1µm) or better. The specification also notes that the resolution of the measuring system should be 10µ” (2.5µm) or better. Of course these two callouts alone do not make for a perfect measurement.
