The AEMC MN82 AC Current Probe  is designed specifically for use with the AEMC 6471 and 6472 Ground Resistance Tester.  When a single probe is used in conjunction with the traditional fall-all-potential method, selective grounds can be measured by moving the probe from point to point around the grounding system.

When two MN82 probes are used in conjunction with the AEMC 6471 and 6472, grounding electrodes can be measured without the necessity of installing auxiliary rods and conducting a full potential measurement. This is also referred to as the stakeless method.
