TES-1605 Digital Earth Tester
•Data hold function.
•Auto power off function:
The timer operates automatically for about 10 minutes when the “ Test Button Switch ” is pressed to keep the tester powered 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 a simplified two-wire measuring system are also supplied as standard accessories.
•Automatic warning when the resistance of auxiliary earth spike is in excess of tolerance.
•Designed to meet EN 61010-1/ / EN 61557 safety standard.
•Zero ohm adjustment
