Compliance West GFM-300A-DM Ground Continuity Tester, 3-300A Output

The GFM-300A-DM is designed for testing where very high currents are needed to judge connection resistance. The front panel allows adjustment of the AC current up to 300A with a max load of 0.010Ω. The dual digital meter front panel simultaneously displays both current through and voltage across the grounding circuit of the unit under test. Provided with premium leads and alligators, manual and calibration certificate.
