SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-033: Particular requirements for hand-held multimeters
for domestic and professional use, capable of measuring MAINS voltage
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

5.1.5.101 Measuring circuit
Measuring circuit TERMINALS shall be marked with the value of the RATED voltage to earth.
Each pair or set of measuring circuit TERMINALS that are intended to be used together shall be
marked with the value of the RATED voltage or the RATED current as applicable to the pair or
set of TERMINALS.
Measuring circuit TERMINALS are usually arranged in pairs or sets. Each pair or set of
TERMINALS may have a RATED voltage or a RATED current, or both, within that set, and each
individual TERMINAL will have a RATED voltage to earth. For some hand-held multimeters, the
RATED voltage between TERMINALS may be different from the RATED voltage to earth. Markings
shall be clear to avoid misunderstanding.
IEC 61010-2-033:2019 © IEC 2019 – 11 –
TERMINALS of measuring circuits RATED for MAINS voltage measurements shall be additionally
marked "CAT lll" and/or "CAT IV" as applicable. Marking those TERMINALS with these two
types, and only these two types, of MEASUREMENT CATEGORY and its RATED voltage to earth, is
permissible. Marking MEASUREMENT CATEGORY II is not allowed.
Measuring circuit TERMINALS that do not have a RATING for connection to voltages above the
levels of 6.3.1, may be marked with alternative markings.
Measuring circuit TERMINALS which are dedicated only for connection to specific TERMINALS of
other equipment need not be marked provided that there is a means of identifying these
TERMINALS.
TERMINAL markings shall be visible when the hand-held multimeter is ready for NORMAL USE
with connectors and TERMINALS mated and shall reference the applicable TERMINALS.
Conformity is checked by inspection.
5.2 Warning markings

6.6.101 Measuring circuit TERMINALS
The conductive parts of each unmated measuring circuit TERMINAL which could become
HAZARDOUS LIVE when the highest RATED voltage is applied to other measuring circuit
TERMINALS on the hand-held multimeter shall be separated by at least:
a) for TERMINALS with voltage RATING up to 1 000 V a.c. or 1 500 V d.c., the applicable
CLEARANCE and CREEPAGE DISTANCE of Table 101 from the closest approach of the test
finger touching the external parts of the TERMINAL in the least favourable position (see
Figure 1);
b) for TERMINALS with voltage RATING exceeding 1 000 V a.c. or 1 500 V d.c., 2,8 mm for the
CLEARANCE and CREEPAGE DISTANCE from the closest approach of the test finger touching
the external parts of the TERMINAL in the least favourable position. These TERMINALS shall
also withstand the voltage test of 6.8 with a test voltage equal to the RATED voltage of the
TERMINAL multiplied by 1,25 applied between the closest approach of the test finger
– 14 – IEC 61010-2-033:2019 © IEC 2019

when it is applied to that TERMINAL or to any other compatible TERMINAL, with the range
and function settings set in any possible manner (see 101.3).
c) Any interconnections between the hand-held multimeter and other devices or accessories
intended to be used with the hand-held multimeter shall not cause a HAZARD even if the
documentation or markings prohibit the interconnection while the hand-held multimeter is
used for measurement purposes (see 6.6).
d) Other HAZARDS that could result from REASONABLY FORESEEABLE MISUSE shall be addressed
by RISK assessment (see Clause 16 and Clause 17).
e) A TEMPORARY OVERVOLTAGE or a TRANSIENT OVERVOLTAGE applied on the measuring circuit
TERMINALS in a voltage measurement function shall not cause a HAZARD (see 101.4).
Conformity is checked as specified in 6.6, Clause 16 and Clause 17, 101.2, 101.3 and 101.4,
