Introduction

JJF 1071-2010 "National Calibration Specifications writing rules", JJF 1001-1998 "common terminology and measurement Definitions ", JJF 1059-1999" Evaluation and Expression of Uncertainty in Measurement ", JJF 1094-2002" measuring instrument characteristics Assessment ", JJG396-2002" inductance micrometer "constitute support calibration specification revision of the basic series specification. Compared with JJG396-2002 "inductance micrometer", in addition to editorial changes, the major technical changes to this specification as follows. --- The calibration specifications to test procedures be revised; --- Abolition of the "discrimination", "response time" metrological characteristics requirements; --- Calibration method "load" requirements of the metrological characteristics have been modified to increase the load changing requirements; --- Will "show the value of stability," the description to "drift", modified digital Inductance Sensor drift technology index; --- Original procedure with the same amount of 2 blocks pairing method or the direct method of calibration error indication to the amount of the block (or 2, etc. 3, etc.); --- Added Appendix B, C, D. The previous versions of the release JJG396-2002 case. --- JJG396-1985, JJG804-1993. Inductance Sensor Calibration Specification

1 Scope

3 Terms

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.
