ASTM G 57
Capable of measuring earth voltage (V A.C.) 2mA measuring current permits the testing of earth resistance without tripping earth leakage current circuit breakers in the circuit. Auto power off function. The timer operates auto power off function. The time operates the "PUSH BUTTON SWITCH" and "TIMER ON BUTTON' are pressed together. This will keep the test "NO" for about three to five minutes. Then auto power off.
