La description

EY200 is an earth resistance tester for testing power distribution lines, in-house wiring system, electrical appliances etc. It also has an earth voltage range for earth voltage measurement. Features: Designed to safety standard IEC 61557 Reference to IEC 60529: Degrees of protection provided by enclosures (IP54). Measurement can be made even under adverse weather conditions Large, easy-to-read LCD digital display 2P Test leads (for simplified measurement) has a structure that both the safety alligator clip and the test probe are available Warns when earth resistance of auxiliary earth spikes exceeds the permissible limit Convenient carrying soft bag for accessories etc. 3-Pole Earth Resistance Measurement (Precise Measurement) 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.

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. 2-Pole Earth Resistance Measurement (simplified measurement) 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.''
