Safety Precautions - Chauvin Arnoux C.A 6511 Manual De Instrucciones

- 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.
- When the insulation measurement is finished, leave the instrument connected for a few
seconds to allow automatic discharge of the high tension of the device tested.
- During measurement of continuity or resistance, the voltage should be measured first.
The presence of a voltage van activate protection and necessitate changing the fuses.
On the -10Ω +10Ω and 1000Ω ranges, the instrument is protected by an HBC fuse. On the
other ranges the instrument is statically protected on all the ranges from a voltage of
600V rms applied permanently between the terminals and from a voltage of 1000V rms
accidentally applied for less than 15 seconds between the terminals.
- Position the switch in the OFF position when the instrument is not used.
