Digital Earth Tester
- 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.
