Foreword
This standard replaces GB/T 13978-1992 "Digital Multimeter General technical requirements."
The standards are compared with the GB/T 13978-1992 major changes are.
--- Comprehensively revised the inspection rules and compliance criteria.
--- Revised logo, packaging, storage requirements.
--- Canceled a standard feature of test items in Table 7 to Appendix C test items and replace substandard classification.
This standard appendix A, Appendices C and D are normative appendix, Appendix B is an informative annex.
Since the implementation of this standard, the original national standard GB/T 13978-1992 repealed.
