Autotest

In case of using C.A 751 with C.A 704 / 760
/ 765 tester, always perform an autotest
immediately before and after using the
adapter.
Never use if the autotest is incorrect.
Implementation:
I Position the C.A 751 adapter in place of the
C.A 760 / 765 / 704 tester's test probes
I Press the autotest button and check that
the autotest is correct by referring to the
operating manual of the C.A 704 or C.A 760
or C.A 765 detector.
Note: The autotest does not cover the
activation of the LEDs (which simply make
the instrument easier to read). However,
during phase identification tests, if the tester
indicates the presence of a voltage of 127
or 230 V, the LED on the phase side lights up.

Electrical socket wiring diagnosis

I Plug the adapter or the pack tester with
adapter into the power socket to be tested.
I The C.A 751 has three LEDs which indicate
the status of the power socket and the phase
position.
If the socket is wired correctly, the central
LED and one of the two outer LEDs light up.
The outer LED indicates the position of the
phase.
Example:
Neutral
Socket OK
