Digital Earth Tester TES-1605

Capable of measuring earth voltage.  Data hold 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.  Automatic warning when resistance of auxiliary earth spike is in
excess of tolerance.  Designed to meet IEC1010-1 safety standard.  Zero ohm adjustment.
