the voltage detector may discharge temporarily the interfer-

the original value when the voltage detector is removed.
When the indication “voltage present” does not appear,
it is highly recommended installing earthing equipment
before work.

A voltage detector declaring two values of internal im-
pedance has passed a performance test of managing
interference voltages and is (within technical limits) able to
distinguish operating voltage from interference voltage and
has a means to directly or indirectly indicate which type of
voltage is present.

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).

to be checked. Check that they are correctly connected and
that the test probes are actually touching, then press the
AUTO TEST button again.
If the problem persists, replace the batteries and try again.
If the problem persists with new batteries, the lead and/or
the test probes must be replaced.
If no indicator lights, replace the batteries (see §5.2). If the
problem persists with new batteries, the device is defective
and must be sent in for repair.

3.2. 2.2. VOLTAGE DETECTION
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.
