IEC 61010-2-033 Ed. 2.0 b:2019

Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-033: Particular requirements for hand-held multimeters and other meters for domestic and professional use, capable of measuring mains voltage

IEC 61010-2-033:2019 is available as IEC 61010-2-033:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61010-2-033:2019 specifies safety requirements for hand-held multimeters for domestic and professional use, capable of measuring mains. Hand-held multimeters are multi-range multifunction measuring instruments intended to measure voltage and other electrical quantities such as resistance or current. Their primary purpose is to measure voltage on a live mains. They are suitable to be supported by one hand during normal use. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
 - The scope has been reduced to hand-held multimeters. Voltmeters and clamp multimeters have been removed. They are addressed respectively by IEC 61010-2-030 and IEC 61010-2-032. The relevant definitions have been removed.
 - Subclause has been relocated into Clause 102.
 - Clearances and creepage distances for wet locations and for measuring circuit terminals exceeding 1 000 V a.c. or 1 414 V d.c. have been specified.
 - Subclause 14.101 related to "Circuits or components used as transient overvoltage limiting devices in measuring circuits used to measure mains" has been removed.
 - References to IEC 61010-031 for probe assemblies and IEC 61010-2-032 for current sensors have been added.
 - Requirements for protection against mains overvoltage measuring circuits have been added.
 - Clause 102 has been rewritten.
 - Requirements for measuring circuits from 1 000 V to 3 000 V have been added.
 - An informative Annex CC about dimensions of 4-mm banana terminals has been added.
 - A flowchart for insulation according to the type of circuit has been added in a new Annex DD.
