Current Measurement; Measurement Principle; Use - Chauvin Arnoux AmpFlex A110 Notice De Fonctionnement

2.1. MEASUREMENT PRINCIPLE

The sensors use the principle of the Rogowski coil.
The sensor used achieves:
„ very good linearity and no saturation effect (and so no overheating);
„ a wide measurement dynamic, up to several kA;
„ insensitivity to DC (measurement of the AC component of any AC + DC signal);
„ light weight (no magnetic circuit).

2.2. USE

2.2.1. CONNECTING THE A110
Connect the output leads to a measuring instrument having an input impedance ≥ 1 MW. Switch it on
and set to AC voltage measurement.
