English SAFETY PRECAUTIONS - Before any measurement check that there is no voltage present on the circuit to be tested. - Use the appropriate leads supplied with the instrument. - At rest, the needle must indicate 0 on the voltmeter scale. If not, adjust it by means of the central (6) zero reset screw.
Connect the instrument to the installation to be tested using the accessories supplied (leads and crocodile clip). It is preferable that the "+" is connected to the earth. Select an insulation measurement position with the switch (500 V for the C.A 6511, 500 or 1000 V for the C.A 6513).
CONTINUITY MEASUREMENT After having connected the instrument to the installation to be tested, you must check that no voltage is present (see "Insulation measurement/voltage"). Set the switch to the "10 Ω" position. The measurement is done automatically without having to press the yellow button. Read the value on the white scale 0 to 10 Ω.
This instrument should be checked at least once a year. For checks and calibrations, contact one of our accredited metrology laboratories (information and contact details available on request), at our Chauvin Arnoux subsidiary or the branch in your country. REPAIRS-MAINTENANCE For all repairs before or after expiry of warranty, please return the device to your distributor.
