UL Standard for Safety Electrical Equipment for Measurement, Control, and Laboratory Use; Part 2: Particular Requirements for Hand-Held Probe Assemblies for Electrical Measurement and Test First Edition
Replacement：
This International Standard applies to hand--held and hand--manipulated PROBE ASSEMBLIES of the types
described below，and related accessories These PROBE ASSEMBLIES are for use in the interface between an
electrical phenomenon and a measuring or test instrument They may be stand-alone PROBE ASSEMBLIES
which are themselves within the scope of part 1，or accessories to other equipment within the scope of
pa rtl
a)Low—voltage and high—voltage，non—attenuating PROBE ASSEMBLIES(type A)
Non-attenuating PROBE ASSEMBLIES for direct connection to voltages not exceeding 63 kV r m s or
d．c They do not incorporate active components，nor are they intended to provide a voltage
divider function or a signal conditioning function，but they may contain passive non-attenuating
components such as fuses
b)High-voltage attenuating or divider PROBE ASSEMBLIES(type B)
Attenuating or divider PROBE ASSEMBLIES for direct connection to voltages exceeding 1 kV r m s or
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 in the test or measu ring equipment intended to be used with the
c)Low-voltage attenuating or divider PROBE ASSEMBLIES(type C)
Attenuating，divider or other signal conditioning PROBE ASSEMBLIES for direct connection to voltages
exceeding 30 V rm s or42，4 V peak or 60 V d c，but not exceeding 1 kV r m s，peak or d c
The signal conditioning function may be carried out wholly within the PROBE ASSEMBLY，or partly
within the test or measuring equipment intended to be used with the PROBE ASSEMBLY
