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.
- 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 -10W +10W and 1000W 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.

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 scale of the galvanometer :
- 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 MW . 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).
13
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 W" position.
The measurement is done automatically without having to press the yellow button. Read the
value on the white scale 0 to 10 W. Then set the switch to the "-10 W" position and check that
the needle of the instrument indicates the same continuity value. If this second value is
different from the preceding one you must make the following calculation :
R
= R+10 W + R-10 W
continuity
2
To have a better measurement accuracy on the +10 W and -10 W ranges, measure the
resistance of the leads by short-circuiting them. Then subtract this value from the measured
resistances.
Remarks : - In order to save battery power, it is preferable to disconnect the leads once
the continuity measurement has been finished.
- If the instrument, on continuity measurement, is not connected, or is badly
connected, the needle then positions itself to the far right.
RESISTANCE MEASUREMENT (C.A 6513 only)
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 "1000 W" position.
The measurement is done automatically without the need to press the yellow button.
Read the value on the white scale 0 to 10 W, applying a coefficient x100.
Remarks : - If the instrument, on resistance measurement, is not connected, or is badly
connected, the needle then positions itself to the far right.
- In order to save battery power, it is preferable to disconnect the leads once
the resistance measurement is finished.

MAINTENANCE
CHANGING THE BATTERIES/FUSE
Check that no terminals are connected and that the switch is in the OFF position before
opening the instrument. For safety, the instrument can only be opened if the leads are
disconnected from the terminals. Access to the fuses and the batteries is by opening the back
of the case.
Remove the shockproof case if there is one, then undo the tool release screws with a
screwdriver and remove the back of the case.
Warning : never press the yellow button when the case is open.

FITTING THE SHOCKPROOF CASE
In order not to damage the window protecting the display, it is preferable to first engage the
upper part of the instrument in the case, then to push the lower part in.
CLEANING
Clean the case of the instrument with a soft damp cloth. Use soapy water but not alcohol,
solvents or hydrocarbons.
REPAIRS-MAINTENANCE
The maintenance operations must be done with original parts, and by an approved service
department. To obtain a good quality measurement, it is preferable to recalibrate every two
years, or every year in case of intensive use.
