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


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.
International Standard IEC 61010-2-33 has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.

INTRODUCTION
IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment
within its scope. For certain types of equipment, the requirements of IEC 61010-1 will be
supplemented or modified by the special requirements of one, or more than one, particular
part 2‘s of the standard which must be read in conjunction with the Part 1 requirements.
This Part 2-033 specifies the safety requirements for HAND HELD METERS that have a primary
purpose of measuring voltage on a live MAINS CIRCUIT.
Part 2-032 specifies the safety requirements that are generally applicable to HAND-HELD and
hand-manipulated current sensors.
Part 2-030 specifies the safety requirements for testing and measuring circuits which are
connected for test or measurement purposes to devices or circuits outside the measurement
equipment itself.
VOLTMETER and similar equipment that are not within the scope of Part 2-033 are considered
to be covered by the requirements of Part 2-030 or Part 2-032. But for equipment within the
scopes of both Part 2-032 and Part 2-033, the two standards must be read in conjunction.

Replacement:
Replace existing item d) with the following item d):
TERMINALS supplied from the interior of the equipment or from other TERMINALS and which
d)
could be HAZARDOUS LIVE, with the voltage, current, charge or energy value or range, or
with symbol 12 of Table 1.
Addition:
Add the following new subclause:
5.1.5.101 Measuring circuit TERMINALS
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
RATED voltage or the RATED current as applicable to the pair or
marked with the value of the
set of TERMINALS.
NOTE 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 equipment, the measurement RATED voltage (between TERMINALS) is different from the RATED
voltage to earth.
Measuring circuit TERMINALS RATED for MAINS CIRCUITS voltage measurements shall be
additionally marked “CAT lll” or “CAT IV” as applicable.

shall meet the following requirements.
Warning markings shall be visible when the equipment is ready for NORMAL USE. If a warning
applies to a particular part of the equipment, the marking shall be placed on or near the part.
The size of warning markings shall be as follows.
a) Symbols shall be at least 2,75 mm high. Text shall be at least 1,5 mm high and contrast in
colour with the background.
b) Symbols or text moulded, stamped or engraved in a material shall be at least 2,0 mm
high. If not contrasting in colour, they shall have a depth or raised height of at least
0,5 mm.
If it is necessary for the RESPONSIBLE BODY or OPERATOR to refer to the instruction manual to
preserve the protection afforded by the equipment, the equipment shall be marked with
symbol 14 of Table 1. Symbol 14 is not required to be used with symbols which are explained
in the manual.
If the instructions for use state that an OPERATOR is permitted to gain access, using a TOOL, to
a part which in NORMAL USE may be HAZARDOUS LIVE, there shall be a warning marking which
states that the equipment must be isolated or disconnected from the HAZARDOUS LIVE voltage
before access.
