This device is compliant with safety standard IEC/EN 61010-2-034 or BS EN 61010-2-034 and the leads are compliant with IEC/EN 61010-031 or BS EN 61010-031 for voltages up to 600 V in category III. Failure to observe the safety instructions may result in electric shock, fire, explosion, or destruction of the instrument and of the installations.

■ The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument..
■ Do not use the instrument on networks of which the voltage or category exceeds those mentioned..
■ Never exceed the protection limits stated in the specifications.
- Observe the conditions of use, namely the temperature, the relative humidity, the altitude, the degree of pollution, and the place of use.
■ Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.
■ Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping.
■ Use only the leads and accessories supplied. Using leads (or accessories) of a lower voltage or category reduces the voltage or category of the combined instrument + leads (or accessories) to that of the leads (or accessories).
■ Use personal protection equipment systematically.
■ When handling test probes and crocodile clips, keep your fingers behind the physical guard.
■ All troubleshooting and metrological checks must be performed by competent and accredited personnel.

1.3. INSERTING THE BATTERIES

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.

■ Remove the protecting sheath.
■ Turn the instrument over.
■ Unscrew the captive screws using a screwdriver.

Captive screws Stand Fuse Batteries

■ Withdraw the back of the case.

3. USE

3.1. PRECAUTIONS FOR USE

At rest, the needle must indicate 0 on the voltmeter scale. If not, adjust it by means of the mechanical zero set screw.
■ Position the switch in the OFF position when the instrument is not used..

3.2. BATTERY TEST

Before starting a measurement campaign, make sure that the batteries powering the instrument are sufficiently charged. Place the switch in the OFF position, press the yellow button, and check the battery status on the galvanometer scale

■ if the needle is in the green zone, the batteries are sufficiently charged,
■ if the needle is in the red zone, all four batteries need changing.

3.3. INSULATION AND VOLTAGE MEASUREMENT

Once you have ensured that the batteries are sufficiently charged (see § 3.1), you can take insulation measurements.

■ Connect the instrument to the installation to be inspected using the accessories supplied (leads, probe tip and crocodile clip). It is preferable for the + terminal to be earthed.
■ Use the switch to select an insulation measurement position: 500 V for the C.A 6511, 500 or 1000V for the C.A 6513.
At this point, the device automatically switches to AC voltmeter mode. It measures the voltage between the + and - terminals.
■ If it indicates no voltage, the insulation measurement can be taken.
If it indicates the presence of voltage on the circuit to be measured, you should not take an insulation measurement. Find the source of the voltage and remove it.
■ Start the insulation measurement by pressing the yellow button. The instrument generates a high voltage between the + and - terminals. The reading is taken directly on the yellow logarithmic scale from 0.1 to 1000 MΩ. As soon as the button is released, the device returns to voltage measurement. The high voltage present on the device under test is discharged via the leads in the instrument. The instrument must therefore be left plugged in for a few seconds once the measurement is complete (measurement returns to 0 V).

3.4. CONTINUITY MEASUREMENT

■ After connecting the instrument to the installation to be tested, check that there is no voltage (see § 3.3).
■ Then set the switch to the +10 Ω position. The measurement will be taken automatically without having to press the yellow button. Read the value on the white scale 0 to 10 Ω.
■ Then set the switch to the -10 Ω position and make sure that the pointer on the device indicates the same continuity value.
■ If this second value is different from the previous one, take the average:

$$ R \text { continuity } = \frac {R _ {+ 1 0 \Omega} + R _ {- 1 0 \Omega}}{2} $$

For a more accurate continuity measurement, measure the resistance of the leads by short-circuiting them. Then subtract this value from the measured resistances.

Notes:

■ To save battery power, disconnect the leads once the continuity measurement is complete.
■ If the instrument is not connected, or connected incorrectly, the needle will move to the right.

3.5. RESISTANCE MEASUREMENT (C.A 6513)

■ After connecting the instrument to the installation to be tested, check that there is no voltage (see § 3.3).
■ Set the switch to the 1000 Ω position. The measurement will be taken automatically without having to press the yellow button.
- Read the value on the white scale 0 to 10 Ω, applying a x100 coefficient.

Notes:

■ To save battery power, disconnect the leads once the resistance measurement is complete.

■ If the instrument is not connected, or connected incorrectly, the needle will move to the right.
