It is capable of measuring earth voltage (V A.C.) 2mA measuring current allows the testing of earth protection without stumbling earth leakage current circuit breakers in the circuit. Auto power off function. The clock operates auto power off function. The time works the \\\"PUSH BUTTON SWITCH\\\" and \\\"TIMER ON BUTTON\\\' are squeezed together. This will keep the test \\\"NO\\\" for around three to five minutes. At that point, auto controls off. Battery worked Data hold work Small and lightweight IEC 1010 CAT III 200V Calibration performed with provided test drives Measurement Ranges Earth Resistance: 0-20W/0-200W/0-2000W Earth Voltage: 0-200V AC (40-500Hz).
