Safety requirements for electrical equipment for measurement@ control and laboratory use – Part 031: Safety requirements for hand-held and hand-manipulated probe assemblies for electrical test and measurement (Edition 2.1; Consolidated Reprint)
Probe assemblies included in scope This part of IEC 61010 specifies safety requirements for hand-held and hand-manipulated probe assemblies of the types described below@ and their related accessories. These probe assemblies are for direct electrical connection between a part and electrical test and measurement equipment. They may be fixed to the equipment or be detachable accessories for the equipment. a) Type A: low-voltage and high-voltage@ non-attenuating probe assemblies. Non-attenuating probe assemblies that are RATED for direct connection to voltages exceeding 30 V r.m.s.@ 42@4 V peak@ or 60 V d.c.@ but not exceeding 63 kV. They do not incorporate components which are intended to provide a voltage divider function or a signal conditioning function@ but they may contain non-attenuating components such as fuses (see Figure 1.) b) Type B: high-voltage attenuating or divider probe assemblies. Attenuating or divider probe assemblies that are RATED for direct connection to secondary voltages exceeding 1 kV r.m.s. or 1@5 kV d.c. but not exceeding 63 kV r.m.s. or d.c. The divider function may be carried out wholly within the probe assembly@ or partly within the test or measurement equipment to be used with the probe assembly (see Figure 2). c) Type C: low-voltage attenuating or divider probe assemblies. Attenuating or divider probe assemblies for direct connection to voltages not exceeding 1 kV r.m.s. or 1@5 kV d.c. The signal conditioning function may be carried out wholly within the probe assembly@ or partly within the test or measurement equipment intended to be used with the probe assembly (see Figure 3). d) Type D: low-voltage attenuating@ non-attenuating or other signal conditioning probe assemblies@ that are RATED for direct connection only to voltages not exceeding 30 V r.m.s.@ or 42@4 V peak@ or 60 V d.c.@ and are suitable for currents exceeding 8 A (see Figure 4).
