3 Terms and Definitions
  Encoder zero error:
  Encoder error is zero when the encoder from the positive and negative directions at different positions back to its zero position, the maximum variation of its angular position.
4 Overview
  The encoder mainly grating disk or encoder as a measuring element for measuring the corner. It may be used alone as an angle measuring instruments, it can be used as a device or instrument parts goniometer. Law-abiding grade, the encoder can be divided into seven.
5 Metrological characteristics
5.1 Error
Encoder levels indexing error requirement in Table 1
5.2 angle measurement repeatability
Goniometer encoder repeatability requirement levels are shown in Table 1
5.3 encoder zero error
Encoder zero position error requires manufacturers of products specified in the standard, also determined by the user as needed.
5.4 goniometer return error
Goniometer return encoder error requires manufacturers of products specified in the standard, also determined by the user as needed.
