Digital Earth Tester
Digital Earth Tester
- Capable of measuring earth voltage.
- Data hold , MAX / MIN function.
- Auto power off function: The timer operates automatically about 3 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.(unit can be hung from the neck for simplified measurement).
- Automatic warning when resistance of auxiliary earth. Spikes is in excess of tolerance.
- Designed to meet EN61010-1 safety standard.
- Zero ohm adjustment
