PRECAUTIONS FOR USE
This device is protected against voltages up to 1000V with respect to earth in measurement category IV.
The protection provided by the device may be compromised if it is used other than
as specified by the manufacturer and so endanger the user.
Do not exceed the maximum rated voltage and current and the measurement
category. Do not use your instrument on networks of which the voltage or category
exceeds those stated.
Comply with the conditions of use, namely the temperature, the humidity, the
altitude, the degree of pollution, and the place of use.
When handling the test probes, keep your fingers behind the physical guard.
Use connection accessories of which the measurement category and service volt-
age are at least equal to those of the device.
Do not use the device if it is open, damaged, or poorly reassembled, or its acces-
sories if they seem to be damaged.
The device must be kept clean so that the condition of the cable insulators, housing,
and accessories can be checked. Any component whose insulator is damaged
(even partially) must be sent for repair or scrapped.
The device is designed to be used by qualified personnel and in compliance with
national safety rules.
We recommend wearing personal protective equipment when the environment in
which the device is used makes it necessary.
All troubleshooting and metrological checks must be done by competent, ac-
credited personnel.

1.5. FUNCTIONALITY
The C.A 773 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 773 is Voltage Absence Testing (VAT). It detects hazardous voltages, i.e. higher than ELV (extra-low voltage) 50 Vac or 120 Vdc), even if
the device’s batteries are spent or absent.
Its other functions are:
Indicating a voltage between 12 and 1000 Vac or 1400 Vdc with polarity indication.
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 773 are nominal voltages. Ensure that it is used
on voltage-normalized networks.

2. USE
+
+
This device is a detector. The indications it provides must not be used for measurement purposes.
2.1. SELF-TEST
Before using the C.A 773, run a self-test. This checks the integrity of the cable and
the test probes, correct operation of the electronic circuit, and a sufficient voltage
level for the batteries.
Connect the red test probe to the + terminal and the black test probe to the L1
terminal.
Bring the two test probes into contact and press the AUTO TEST button. Hold it
down as long as necessary.

with new batteries, the device is defective and must be sent for repair (see § 4.4).
Repeat the self-test after each measurement to confirm that the device is operating properly.
In a noisy atmosphere, ensure that you are able to hear the buzzer.
Note: If the AUTO TEST button is held down for more than 10 seconds with the test
probes not in contact, the device goes into stand-by mode.

2.5. PHASE DETECTION
+
The C.A 773 performs single-pole phase detection.. This means that you can connect just one test probe to find out if a phase is present.
To operate properly, phase detection must be used on earth-referenced networks.
This means, for example, that you can locate the phase on a connector for an
earth-referenced network.
Connect the black test probe to terminal L1.

The device displays “measurement” to indicate that it is making the measurement.
If there is a problem, i.e. if the device does not detect a phase change within 10
seconds or if the phases are not balanced, it indicates an error by emitting two
low-pitched beeps and displaying “error”.
Otherwise, the device indicates the phase order by lighting up:
L123 and emitting a low-pitched beep followed by a treble beep,
or L132 and emitting a treble beep followed by a low-pitched beep

During voltage detection, if there is an interference voltage near the element being
tested, the device may indicate the presence of an operating voltage when in fact
there is none.
If this voltage is < 400 V, press the two buttons
to distinguish an interference
voltage from an operating voltage. If it is an interference voltage, the voltage indication disappears while the buttons are being pressed.
On systems equipped with 30 mA differential circuit breakers, they can be triggered
by pressing these two buttons.
Place the + test probe on the phase, and the black test probe on the protection
conductor, where these two conductors belong to the circuit protected by the differential circuit breaker to be tested.
A voltage indication appears on the bargraph and on the digital display.

probe).

If the voltage measured is between 8 Vrms and 400 Vrms, the test is triggered.
If the voltage is 230 Vrms, the 30 mA differential circuit breaker is triggered and the
voltage disappears from the bargraph and from the digital display.
This test generates a high current that heats the device. When it is too hot, you must
wait for it to cool before resuming the use of this function.
2.8. IP2X TEST PROBES
IP2X test probe leads are delivered with the device (C.A 773 IP2X) or as an option
(C.A 773) according to the model ordered.
The use of IP2X accessories is an additional safety feature. These accessories may
be mandatory in certain countries.
In France, their use is imposed by standards (NF C 18-510, UTE C 18-510) and
government decrees.
Connect the red IP2X test probe to the + terminal and the black IP2X test probe
