The Yokogawa EY200 Digital Earth Tester uses 3-pole or 2-pole measuring methods. To use the 3-pole method 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.
The 2-pole measuring method is a simplified method and 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.
