Autotest; Voltage Detection - Chauvin Arnoux C.A 711 Manual De Instrucciones

3. AUTOTEST

Always perform an autotest before using your detector.
Never use it if the autotest is incorrect.
3.1 The autotest function allows you to check that the whole
detector is functioning correctly: the touch prods, the LEDs*,
the lead, the electronics, the buzzer and the batteries.
*: except for the
Implementation
Connect the brown touch-prod lead to the "L3" terminal and
press the trigger to extend the brown touch prod.

prod.
Bring the instrument's green touch prod into direct contact
with the touch prod on the brown lead.
Press the autotest button.
Result
All the LEDs must light up except the "
buzzer must sound: the autotest is correct.
NB: To test the continuity of the yellow lead, switch it with the
brown lead and redo an autotest.
The battery charge life is indicated by the flashing LED:
- low batt - 50 V LED flashing: 25% battery charge life
(1)
remaining .
- 127 V LED flashing: 50% battery charge life remaining
- 230 V LED flashing: 75% battery charge life remaining
- 400 V LED flashing: 100% battery charge life remaining.
(1) You are advised to change the batteries (see 11.1).
If the autotest is incorrect, change the batteries or carry out
repairs.
3.2 "Risk of electric shock" LED
If the red " " LED comes on, immediately stop all detection
and perform an autotest (see 3.1).
Case 1: the batteries are too low or absent. Change the batte-
ries (see 11.1). The detector has an additional safety function
which indicates the presence of a voltage greater than 50 V
even if the batteries are dead.
Case 2: the batteries are satisfactory but a voltage of between
25 V and 50V is present on the touch prods.

4. VOLTAGE DETECTION

Always perform an autotest before using your detector.
Never use the detector if the autotest is incorrect.
Voltage detection is performed between the "L1" and "L3"
terminals only.
Connect the brown touch-prod lead to the "L3" terminal and
press the trigger to extend the brown touch prod.
