  • Page 12 2. Earth Voltage Testing: Turn the rotary switch to select EARTH VOLTAGE. Connect the test leads to terminal V and E, and then connect to the testing points. LCD display will display earth voltage value. Voltage Measurement Range Accuracy 0 -400V AC, 50/60 Hz ±(1% Rdg + 6 LSD) Note:Do not press the TEST button when measuring the earth voltage.
  • Page 13 Check the wiring connections, if soil is too dry, or if auxiliary earth stakes are within the specified measurement distance. When the earth resistance is greater than the selected measuring range, LCD display will show “OL”(overload). 4. Auto Power Off: The tester will turn itself off after 10 minutes when in idle.
