Earth Fault Testing
To check for earth faults on field wiring, select the "Earth Fault Test" from the
main menu.
Connect the wires as described on the TSIT yellow label for the circuit type
you are testing. The GREEN test lead is connected to earth ground, such as
building steel.
To detect every earth fault, you must test the positive lead and the negative
lead of a circuit independently. If there are earth faults on both positive and
negative leads, it might result in a balanced condition, where no earth fault is
detectable when tested as a circuit.
Connect the Red lead per the yellow label on the TSIT, and the Green lead to
earth. Press the ENT key. The display shows the earth test status in real time.
If the display indicates "Positive Earth Fault", you must troubleshoot and
correct the earth fault. If the display indicates "Normal", disconnect the Red
lead and connect the Black lead as described on the label.
