The main function of the C.A 742 is to test for the absence of
any voltage. It detects hazardous voltages, meaning voltages
exceeding the ELV (extra low voltage: 50 Vac or 120 Vdc).
Its other functions are:
„ Indication of a voltage between 12 and 690 Vac or 750 Vdc,
with indication of the polarity.
„ Continuity indication.
„ Indication of the phase position.
The voltages indicated on the C.A 742 are nominal volt-
ages. Make sure that the device will be used on networks at
standardized voltages.
