Foreword

This standard replaces GB/T 13970-1992 "Basic parameters series digital instrument." This standard and GB/T 13970-1992 main differences.

--- According to GB/T 1.1-2000. provisions "Standardization Guide Part 1 standard structure and write rules", modification series Write format;

--- The standard name to read. "The basic parameters of the term digital instrument";

--- Increasing the standard preface;

--- Normative references, increasing the GB/T 13978, GB/T 14913 standard;

--- Added some terminology inductors, capacitors, etc., and the introduction of "uncertainty" concept;

--- Delete "Transform Characteristics" section;

--- Added Appendix A "basic uncertainty and job uncertainty representation." Appendix A of this standard is a normative appendix. The standard proposed by China Machinery Industry Federation. This standard by the National Electrical Instrument Standardization Technical Committee (SAC/TC104) centralized. This standard was drafted.

This standard replaces the standards previously issued as follows:

--- GB/T 13970-1992. The basic parameters of the term digital instruments

1 Scope

GB/T 13970-2008 is the Chinese national standard on basic parameter terms of digital instruments, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 19 August 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 March 2009. Classification: ICS 17.220.20, CCS N23. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the basic parameters of the term digital instrument performance characteristics. This standard applies to the following basic electricity measuring analog to digital converter Or digital meter. DC and AC current; DC and AC voltage; DC and AC power; Power factor or phase; frequency; Resistance, impedance or components thereof. This standard also applies to the basic measurement of electricity meter multi-purpose. In the multi-function instrument, this standard applies only to the above-mentioned basic power measurement functions section. This standard is also applicable to the above basic power as non-power analog measuring instruments. This standard does not specify the term digital instrument parameters with attachments (for example, shunt, high voltage probe, filters, etc.) performance characteristics. This standard does not apply based on the amount of electrical energy is converted to a digital manner of electrical measuring instruments.
