Measurements with accessories

Different measurement accessories enlarge the field of application or add new functions to
your multimeter.
Measurements of DC currents with shunts
- With 100mV test shunts, the C.A 406
allows the measurement of DC currents
up to 100A DC.
- Use the 50µA - 100mV DC range.
- Connect the C.A 406 as shown in the
diagram.
- Read on the 100 scale.
10A Shunt : reading x 0.1
100A Shunt : reading x 1
NB : There is no current limit as long as the
shunts used have a voltage drop of
100mV at the terminals.
Current measurements with current clamps
- Current clamps and miniclamps of the transformer type allow measurements of high AC
currents, without having to open the circuit.
The measurement is done rapidly and in complete safety. Depending on the clamp used
and the ranges concerned, you can measure up to 3600A.
Only put one conductor in the clamp.
For example with the C31 clamp :
- ratio 1mA AC / 1A AC,
- measure up to 1200A AC,
- use the 3A, 300mA and 30mA ranges.
