BATTERY TEST

Before starting a series of measurements, check that the batteries powering the instrument
are good. Place the switch in the OFF position, press the yellow button, and display the
condition of the batteries on the
- if the needle is in the green zone, the batteries are good
- if the needle is in the red zone, change the four batteries

INSULATION/VOLTAGE MEASUREMENT

Once you are sure the power supply is good (see "Battery test"), you can proceed with
insulation measurements.
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).
At this stage, the instrument is thus automatically set to AC voltmeter. The instrument
makes a voltage measurement between the + and - terminals (scale of voltages up to
600 V AC).
- If the instrument does not indicate any voltage present, the insulation measurement can be
made.
- If the instrument indicates the presence of voltage on the circuit to be measured, insulation
measurement must not be made. Find the source of this voltage and suppress it. Insulation
measurements can only be done on this condition.
Proceed with the insulation measurement, by pressing the yellow button. The instrument
generates a high voltage between the + and - terminals. The reading is done on the yellow
log scale 0.1 to 1000 MΩ. As soon as the button is released, the instrument switches to
voltage measurement. The high tension present on the tested device is discharged via the
leads of the instrument. You must therefore leave the instrument connected for a few
seconds once the measurement is finished (needle returns to 0 V).
