Earth Tester EY200 (Digital)

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:

  • 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.

How to Measure Earthing Voltage

  • 3-Pole Earth Resistance Value 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.

  • 2-Pole Earth Resistance Value 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.
