Offering a true RMS AC current measurement, this digital clamp induces a test current into earth systems and measures ground resistance in multi-ground installations without needing to disconnect the ground. Featuring an elliptical clamp shape, this design offers access to cables and earth straps in constrained areas.

Featuring an elliptical clamp shape, this design offers access to cables and earth straps in constrained areas.
Ensuring the job is a breeze, users can easily avoid dirt build-up thanks to the clamp's flat core ends and use the built-in filter function offering increased noise immunity in electrically noisy environments. Operation in dark and restricted areas is facilitated by a display with a backlight and an audible tone associated with the hold key.
