What is an earth-ground tester/ground resistance tester?
EY200 is an earth resistance tester for testing power distribution lines, in-house wiring system, electrical appliances etc. The earth resistance tester by Yokogawa also has an earth voltage range for earth voltage measurement.
EY 200 Digital Earth Meter Features:
Connect the earth/ground electrode (E) and auxiliary spikes (P, C) to the main body using the accessory test lead. Put apart 5 to 10 m between E and P, and P and C, respectively. E, P, and C should be approximately in a line.

A simplified 2-pole measuring method can be used if there is an almost perfectly earth/ground object such as a lead or iron water-pipe (plastic pipes cannot be used) or if there is an object with a known value of earth resistance, near the measurement site.
