pedance has passed a performance test of managing
interference voltages and is (within technical limits) able to
distinguish operating voltage from interference voltage and

2.3. FUNCTIONS
The C.A 762 is a Voltage Detector with indicator lights.
It complies with the requirements of standard IEC 61243-3.
The main function of the C.A 762 is to test for the absence of
any voltage. It detects hazardous voltages, meaning voltages
exceeding the ELV (extra low voltage: 50 V or 120 V).
Its other functions are:
Indication of a voltage between 12 and 690 V or 750 V,
with indication of the polarity.
Continuity level quality indication.
Phase position indication.
Phase order indication.
The voltages indicated on the C.A 762 are nominal volt-
ages. Make sure that the device will be used on networks at
standardized voltages.

3. USE
This device is a detector. The indications it provides must not
be used for measurement purposes.
3.1. SELF-TEST
Before using the C.A 762, perform a self-test. This checks the
integrity of the leads, the proper operation of the electronic
circuit, and the battery voltage.
Connect the red test probe to the + terminal and the black
lead to the COM terminal.
Touch the 2 test probes together and press the AUTO TEST
button. Press for as long as necessary.
If all of the indicators of the device except ELV light and
the audible signal sound, the device is working properly
and can be used.
If every other indicator lights, the batteries must be replaced
(see §5.2).

If the problem persists, replace the batteries and try again.
If the problem persists with new batteries, the lead and/or

3.4. 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.
Warning: Phase detection cannot replace an absence of
voltage test.
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.

If there is a problem, in other words, if the device fails to
detect a change of phase within 10 seconds or if the phases
are not balanced, it reports an error by emitting two low-
pitched beeps.
Otherwise, the device indicates the phase order by lighting:
the L1-L2-L3 indicator and emitting a low-pitched beep,
followed by a high-pitched beep,
or the L1-L3-L2 indicator and emitting a high-pitched beep
followed by a low-pitched beep.
3.6. USING THE C.A 751 (OPTION)
If you have purchased a C.A 751 2P+T adapter, you can test
for the absence of voltage between the phase and neutral
on an outlet.
Attention: Pairing the C.A 762 with the C.A 751 derates
the combined product to measurement category
II, 250V.
Connect the C.A 751 to the terminals of the C.A 762, then
refer to the operating instructions of the CA.751.
Warning: When the C.A 762 is connected to the C.A 751,
the continuity <60 and <300kindications are no
longer valid.

5. MAINTENANCE
Except for the batteries, the instrument contains no
parts that can be replaced by personnel who have not
been specially trained and accredited. Any unauthorized
repair or replacement of a part by an “equivalent” may
gravely impair safety.
5.1. CLEANING

Disconnect the instrument completely.
Use a soft cloth, dampened with soapy water. Rinse with a
damp cloth and dry rapidly with a dry cloth or forced air. Do
not use alcohol, solvents, or hydrocarbons.
5.2. REPLACEMENT OF BATTERIES
If, during the self-test, only half of the indicators light, you
must replace the batteries.
Disconnect anything connected to the device.
Using a screwdriver, unscrew the two captive screws of the
battery compartment cover located on the back of the device.
Withdraw the spent batteries and replace them with two new
batteries (AAA or LR3 1.5V alkaline batteries).
Close the battery compartment cover and make sure that it
is completely and correctly closed.
Screw the two screws back in.
Spent batteries must not be treated as ordinary
household waste. Take them to the appropriate
recycling collection point.
