Digital Earth Tester

Product Features
  • Capable of measuring earth voltage.
  • Data hold function.
  • Auto power off function:
    The timer operates automatically about 10 minutes when the “ Test Button Switch ”are pressed to keep the tester power on.
  • 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
  • In addition to the facility for precision measurement, test leads for simplified two wire measuring system also supplied as standard accessories.
  • Automatic warning when resistance of auxiliary earth spike is in excess of tolerance.
  • Designed to meet EN 61010-1/ / EN 61557 safety standard.
  • Zero ohm adjustment
