This part of IEC 61010 specifies safety requirements for 
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 the circuit being 
measured. They can 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. These current sensors and circuits need additional protective means between the 
current sensor, the circuit and an OPERATOR. 
NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a permanent connection which can be detached only by the use of a TOOL. 
NOTE 2 Some current sensors are also known as current clamps, CLAMP MULTIMETERS and current probes. 
Current sensors are hand-manipulated before and/or after a test or measurement, but do not 
necessarily need to be HAND-HELD during the test or measurement. Current sensors used as 
FIXED EQUIPMENT are not within the scope of this document.dition 4.0 2019-06 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Safety requirements for electrical equipment for measurement, control and laboratory use – Part 2-032: Particular requirements for HAND-HELD and hand-manipulated current sensors for electrical test and measurement Exigences de sécurité pour appareils électriques de mesurage, de régulation et de laboratoire – Partie 2-032: Exigences particulières pour les capteurs de courant, PORTATIFS et manipulés ma
