39、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 2s of the standard which are to be read in conjunction with the Part 1 requirements. This Part 2-032 specifies the safety

40、requirements that are generally applicable to HAND-HELD and hand-manipulated current sensors (see Clause 1). 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 i

41、tself. Part 2-033 specifies the safety requirements for HAND HELD METERS that have a primary purpose of measuring voltage on a live MAINS CIRCUIT. Except for protective bonding, all requirements of Part 2-030 have been included into Part 2-032. Equipment within the scopes of Part 2-030 and Part 2-03

42、2 are considered to be covered by the requirements of Part 2-032. However, for equipment within the scope of both Part 2-032 and Part 2-033, the two standards are to be read in conjunction.

43、NTROL AND LABORATORY USE Part 2-032: Particular requirements for hand-held and hand-manipulated current sensors for electrical test and measurement 1 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

44、the following: This part of IEC 61010 specifies safety requirements for HAND-HELD and hand-manipulated current sensors described below. These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of

45、the circuit being measured. They may be stand-alone current sensors or accessories to other equipment or parts of combined equipment (see Figure 101). These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. T

46、he existence of these current sensors and circuits in equipment requires additional protective means between the current sensor, the circuit and an OPERATOR. NOTE 1 This part includes also the requirements of Part 2-030. Testing and measuring circuits that are not within the scope of this part are c

47、onsidered to be covered by the requirements of Part 1 or other parts 2s of IEC 61010, and then will also need to meet the requirements of these other parts with the exception of Part 2-030. Current clamp meters and similar currents sensors that have a primary purpose of measuring voltage on a live M

48、AINS CIRCUIT are also within the scope of Part 2-033. NOTE 2 Some current sensors are also known as current clamps and current probes. Current sensors require hand manipulation before or after a test or measurement, but do not necessarily need to be HAND-HELD during the test or measurement. NOTE 3 S

49、ome current sensors designed for portable use can also be used for fixed installations. The following types of current sensors are covered: a) Type A: a current sensor designed to be applied around or removed from UNINSULATED HAZARDOUS LIVE conductors. Type A current sensors have defined HAND-HELD or hand-manipulated parts providing protection against electric shock from the conductor being measured, and also have protection against short-circuits between wires and bu
