For certain types of equipment, the requirements of IEC 61010-1 will be supple
29、mented or modified by the special requirements of one, or more than one, particular part 2s 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 liv
30、e 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 o
31、utside 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
32、conjunction. BS EN 61010-2-033:2012 6 61010-2-033 IEC:2012 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 1
33、 Scope and object This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replacement: Replace the existing text with the following: This part of IEC 61010 specifies safety requirements for METERS. The METERS that have a primary purpose of measuring voltage on a live
34、 MAINS CIRCUIT are within the scope of this standard. They have various names, but all of them have capability for measurements of voltages on a live MAINS CIRCUIT. Some of the names given to this equipment are as follows: MULTIMETER; digital MULTIMETER; VOLTMETER; clamp METER (see also Part 2-032).
35、 For the purpose of this standard, the term METER is used for these HAND-HELD measuring instruments. NOTE Parts of the equipment that are not within the scope of this Part 2-033 are considered to be covered by the requirements of Part 1 or other part 2s of IEC 61010 and then will also need to meet t
36、he requirements of these other parts. 1.1.2 Equipment excluded from scope Addition: Add the following new item to the list: aa) IEC 61557 (Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.
