Scope

This part of GB/T 20730 gives an indication of inspection and routine testing of electric and pneumatic instruments with two or more outputs.
South, for example, an acceptance test or a post-repair test. This part can be combined with IEC 61003-1.2016, GB/T 18271.2-2017,
GB/T 18271.3-2017 is used together.
This part of GB/T 20730 is applicable to electric and pneumatic industrial process instruments with measured values as continuous signals. Its setting can be either
Mechanical quantities (such as position, force, etc.) can also be standard signals. These meters can be used as controllers, alarm switches or other similar applications.
The quantitative criteria for acceptable performance of the meter are determined by the manufacturer and the user, and the test report indicates which tests were performed. Manufacturer and
Users can agree on the requirements of this section.

Summary	This standard specifies guidelines for the inspection and routine testing of electrical and pneumatic instruments with two or more outputs, for example, acceptance testing or post-repair testing. This standard can be used in conjunction with IEC 61003-1:2016, GB/T 18271.2-2017, and GB/T 18271.3-2017. This standard of GB/T 20730 is applicable to electric and pneumatic industrial process instruments whose measurement value is continuous signal. The set value can be either a mechanical quantity (such as position, force, etc.) or a standard signal. These meters can be used as controllers, alarm switches or other similar purposes. The quantification criteria for the acceptable performance of the instrument shall be determined through consultation between the manufacturer and the user, and the test report shall state which tests have been performed. manufacturer with
