Introduction
JJG 201 "Indicator type measuring instrument" is written in JJF1002-2010 "National Metrology Verification Regulations
Rules, JJF1059.1-2012 "Measurement Uncertainty Evaluation and Representation" as the basis and basis for JJG 201-
2008 "Indicating Measuring Instruments" was revised. And JJG 201-2008 "Indicating class measuring instrument verification instrument
In addition to the editorial changes, the main technical changes are as follows.
--- Reference file, deleted JJF1001-1998 "General Measurement Terms and Definitions", JJF1059-
1999 "Measurement and Expression of Measurement Uncertainty", JJF1094-2002 "Measuring Instrument Characteristics", added
JB/T 11235-2012 "Indicator Calibration Instrument" and other reference documents;
--- Added a schematic diagram of the subtype type and automatic indicator meter of the indicating type measuring instrument (see Figure 4);
--- Increased the technical requirements, main verification equipment and verification of the 100mm grating type indicator meter
method;
--- Added the measurement performance requirement for the automatic indicator type measuring instrument, that is, the "accuracy of image recognition"
Provisions (see 4.7), general technical requirements ie interaction and basic functions "illumination of image recognition systems should be brightness
Uniform, optical imaging is clear, the image is complete" and the data processing software program of the fully automatic verifier should have
Synchronous display function and other regulations (see 5.2.3, 5.2.4, 5.2.5 and 5.2.6);
--- Removed the repetitive requirements for the CNC dial gauge tester (see 4.8).
--- Revised the measurement interval of the 0mm~50mm segment of the numerical control type indicator calibration instrument (see Table 3 of 6.3.11);
--- Added a grating micrometer verification method indicating the indication error of the measuring instrument (see Appendix E);
--- Revised the "information certificate and the information on the inside of the verification result notice" (see Appendix F).
The previous versions of JJG 201-2008 were released.
---JJG 201-1999, JJG 271-1996 merge;
---JJG 201-1980, JJG 345-1984 merge;

Indicating class measuring instrument verification procedure
1 Scope
This procedure is applicable to fully automatic and semi-automatic indications with a resolution of not more than 0.5μm and a range of not more than 100mm.
The type gauge has a manual index with a division value (or resolution) of not more than 10 μm and a range of not more than 50 mm.
The first verification, subsequent verification and in-use inspection of the metering tool.
2 reference files
This procedure refers to the following documents.
JJG 34 indicator table (pointer, digital display)
JB/T 11235-2012 indicator meter
For dated references, only the dated version applies to this Code; any undated quotation
The latest version (including all amendments) applies to this procedure.
3 Overview
The indicating type measuring instrument (hereinafter referred to as the measuring instrument) is based on a grating scale or a precision lead screw as a measurement standard along a straight line.
The guide rail moves the output length standard value, and measures various indicator gauges by image recognition or direct reading.
Digital display) Instrument for indicating parameters such as error.
The tester is divided into vertical according to the verification method (the measurement axis is vertical when the indicator is checked, see Figure 1, Figure 2) and lying
(Measure the axis level when checking the indicator, see Figure 3, Figure 4); according to the reading mode is divided into direct reading (see Figure 1,
Figure 2, Figure 3) and image recognition (see Figure 4); according to the driving method can be divided into manual, semi-automatic and fully automatic three;
According to the instrument function, it can be divided into a dial gauge tester (see Figure 1), a dial gauge tester (see Figure 2) and a meter calibration instrument.
(See Figure 3 and Figure 4).
