Phase Detection - Chauvin Arnoux C.A 762 Notice De Fonctionnement

2.3. CONTINUITY LEVEL INDICATION
Connect the red test probe to the + terminal and the black
lead to the COM terminal.
Keep your hands behind the guards of the device and of
the test probe.
If the device has been left unused for more than 10 minutes
or has been set to standby, first perform a SELF-TEST in
order to switch it to hot standby.
Place the test probes on the element to be tested and main-
tain a firm contact.

If no voltage is detected, the C.A 762 performs a continu-
ity test.
If the result is:
„ <100W: the first 5 indicators of the bargraph blink one after
another. The device emits a continuous audible signal.
„ Between 100W and 2kW: the first 4 indicators of the
bargraph light.
„ Between 2kW and60kW: the first 3 indicators of the
bargraph light.
„ Between 60kW and 300kW: the first 2 indicators of the
bargraph light.
„ >300kW: the device displays nothing and does not emit
a sound.

2.4. PHASE DETECTION

The C.A 762 performs a unipolar phase detection. This means
that connecting a single test probe is enough to determine
whether a phase is present.
To operate correctly, the phase detection function must be
used on networks referred to earth.
It can be used, for example, to locate the phase on an outlet
of a network referred to earth.
