Direct acting indicating analogue electrical measuring instruments and their accessories - Part 6: Special requirements for ohmmeters (impedance meters) and conductance meters
This part of IEC 60051 applies to direct acting indicating analogue electrical measuring ohmmeters (impedance meters) and conductance meters. This document also applies to some non-interchangeable accessories of ohmmeters (impedance meters) and conductance meters. This document also applies to a direct acting indicating electrical measuring instrument whose scale marks do not correspond directly to its electrical input quantity, provided that the relationship between them is known. This document also applies to electronic devices of ohmmeters (impedance meters) and conductance meters in their measuring and/or auxiliary circuits. This document does not apply to insulation ohmmeters, grounding ohmmeters and external commercial power ohmmeters (impedance meters) and conductance meters.
