Introduction Kyoritsu 4106

Kyoritsu KEW 4106 is a 2/ 3/ 4-wire digital earth resistance/earth resistivity tester, equipped with a microcomputer, for measuring earth resistances and calculating earth resistivities. It has an output voltage of 10 Vrms or lower. This makes it an instrument of choice for measuring earth resistances on installations ranging from in-house wiring systems and electrical appliances to power distribution lines. Sub-results that can be shown on the display include resistance of the auxiliary earth spikes, frequency of test current, voltage and frequency of interference (noise) and residual resistance Rk.
