1.3. TEST PROBES
The tips of the test probes are removable.
1.4. C.A 771 IP2X
See § 2.8.
1.5. FUNCTIONALITY
The C.A 771 is a voltage detector with indicator lights.
It complies with the recommendations of the IEC 61243-3 standard.
The main function of the C.A 771 is Voltage Absence Testing (VAT). It detects haz-
ardous voltages, i.e. higher than ELV (extra-low voltage) 50 V
the device's batteries are spent or absent.
Its other functions are:
„ Indicating a voltage between 12 and 1000 V
„ Indicating the quality of the continuity level.
„ Indicating the phase position.
„ Indicating the phase order.
„ Load switching (controlling the triggering of the 30 mA differential circuit breakers).
The voltages indicated on the C.A 771 are nominal voltages. Ensure that it is used
on voltage-normalized networks.
