The High performance C.A6117 offers excellent measurement stability, even in electrically noisy industrial environments. All the measurements needed to test an electrical installation are available: continuity, resistance, insulation, ground resistance, selective earth measurements, loop impedance and type A and AC RCDs (GFCI circuits). The 6117 can also be used to measure voltage, frequency, AC current (via a current clamp), active power, harmonics and phase rotation.

The C.A6117 is also equipped with type B RCD testing, a built in fuse table and a voltage drop feature.
