Continuity Measurement; Resistance Measurement (C.a 6513 Only) - Chauvin Arnoux C.A 6511 Manual De Instrucciones

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. Then set the switch to the "-10 Ω" 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 :
To have a better measurement accuracy on the +10 Ω and -10 Ω 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
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 Ω" position.
The measurement is done automatically without the need to press the yellow button.
Read the value on the white scale 0 to 10 Ω, 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.
R = R+10 Ω + R-10 Ω
