The Chauvin MA 400D DigiFLEX is used for RMS measurements of current, from 20 mA to 400 A. The sensor takes the form of a flexible coil 17 or 25 cm long, connected by a shielded cord to a small housing containing the signal processing electronics, supplied by a battery. The flexibility of the sensors makes it easier to wrap them round the conductor to be measured, whatever its type (cable, bar, strand, etc.) and its accessibility. The design of the snap‑action coil opening and closing device allows it to be handled while wearing protective gloves.

The range comprises 2 models: the MA400D version, whose measurement range starts at 20 mA, is designed for work in residential conditions and can also be used to check electricity distribution points up to 400 A.

The MA4000D version can be used on higher-power installations in industry and the energy production sector. Although it is a high-performance instrument, the remains very simple to use: 2 buttons are all it takes to start the instrument, deactivate the automatic power-off function, HOLD the value on the display or store the maximum value (MAX HOLD).

It is also particularly practical, as the shape of the casing is designed for comfortable handling, the articulated, magnetic MultiFix system makes it simple to position and the velcro strap facilitates storage.
