3.1 Zero balance zerobalance When converting inductance micrometer range gear, the consistency of each block shown zero value. 3.2 Indication variability thevariationindication Under the same measurement conditions, the measurement was performed on the same instrument repeatedly measuring the maximum difference between the results.

4 Overview

Inductance micrometer is a measure of the amount of displacement of small highly accurate measuring instruments, which consists of axial or next to the inductor sensing Is (probes) to convert the displacement amount into an electrical signal by the display means to be displayed measured. Press significant inductance micrometer The display device is divided into several different explicit, electronic pointer and column three types. Its shape shown in Figure 1, Figure 2, Figure 3.
