1 Scope This part of IEC 61243 is applicable to hand-held two-pole voltage detector s with their accessories (crocodile clips and detachable lead s) to be used in contact with parts of electrical systems:
— for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or
— for d.c. voltages not exceeding 1 500 V.
NOTE The a.c. voltages defined in this standard refer either to phase-to-phase voltages or phase to neutral voltages.
Contact electrode extensions are not covered by this standard.
Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions.
Voltage detectors covered by this standard are not intended to be used for continuous operation.
Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level. This standard also includes provisions for the following supplementary functions when available (see Annex B):
— phase indication,
