Isolation Of The Channels - Metrix ScopiX IV User Manual

General

1.5. Isolation of the channels

ScopiX has 2 or 4 channels that are isolated not only with respect to each other but also with respect to earth (600V CAT III):


Making measurements in systems where the circuits are sometimes at different potentials
can be very dangerous. The danger comes either from undesirable short-circuits via the
instrument or from the potentials themselves.

The process of digital isolation of the grounds uses the same input terminals and acquisition
systems for the oscilloscope and multimeter modes, making it possible, in particular, to
change from one instrument to the other without changing the measurement connection.

With the ScopiX with isolated channels, it is possible to observe the command signals of each
phase of a three-phase chopper, and the output current, without recourse to artifices or
complicated or even dangerous set-ups.

Thanks to the Probix accessories, the operator is informed at all times of the limits of the
instrument (insulation voltage, rated maximum voltage): this is active safety.
