3.7. LOAD SWITCHING
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
voltage from an operating voltage. If it is an interference voltage, the voltage indica-
tion 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 con-
ductor, 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.
Press the two

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.
3.8. 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 to
the L1 terminal.
