ST-1520 3 Wire Digital Earth Resistance Tester
  • Capable of measuring earth resistance and earth voltage.
  • 2mA measuring current permits the testing of earth resistance without tripping earth leakage current breakers in the circuit under test.
  • Auto power off function.
  • The timer operates automatically for about three to five minutes when the "PUSH BUTTON SWITCH" and "TIMER ON BUTTON" are pressed together.
  • This will keep test "ON" for the duration of the timer.
  • Timer for test function (count 3-5 minutes).
  • Battery operated.
