Scope

This document defines the terms and definitions of optical gyroscopic angle meters, specifies the models and basic parameters, technical requirements, inspection conditions, marking and packaging, and describes the inspection methods.
This document is applicable to the design, manufacture, and inspection of optical gyroscopic angle meters with accuracy grades of 1, 2, and 3.
Note: The accuracy grades are divided according to the measurement error of the angular position, where the measurement error of the angular position for Grade 1 is within ±0.2″, for Grade 2 it is within ±1″, and for Grade 3 it is within ±5″.
