DL9110 / DL9118 is connected to correct mains supply via a mains plug or the test probes. The Auto Start function remains enabled if the switch position is changed or the DL9110 / DL9118 is powered off. To disable the Auto Start function press F4.
DL9110 / DL9118 Operating Instructions Note: A Line Impedance measurement is automatically made as part of the Earth Loop Impedance test. The Line Impedance measurement (L-N) and Prospective Short-circuit Current (PSC) can be viewed by simply pressing function key F1, without the need to repeat the test.
DL9110 / DL9118 is connected to correct mains supply via a mains plug or the test probes. The Auto Start function remains enabled if the switch position is changed or the DL9110 / DL9118 is powered off. To disable the Auto Start function press F4.
Note: The DL9110 / DL9118 will determine the fault voltage that may appear on the protective conductor during the test. If the fault voltage is greater than 25V the DL9110 / DL9118 will indicate >25V on the LCD, but the user may proceed with the test.
