Chauvin Arnoux C.A 406 Notice De Fonctionnement page 33

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.

The PAC or E series Hall effect clamps have the same advantages but allow
the measurement of both DC and AC currents. With the C.A 406 they are
used on DC.
For example with the PAC 400B clamp:

ratio 1mV DC or AC / 1A DC or AC.

measure up to 500A DC.

used the 50µA – 100mV and 1V DC ranges.
