F-4 Flexible coil (Φ=630 mm)

Flexible current coil, also known as a Rogowski coil, is useful for testing objects, on which hard clamps cannot be attached. In the measurements of alternating current, flexible coils are connected directly to the meter, whereas for earth resistance testing - the operators additionally use ERP-1 adapter.

The coil is terminated with a 5-pin plug. It is available with different levels of the output signal and different lengths.
