The Loopcheck 107 needs a supply to function and checks the configuration of the supply, the quality of the earth connection and the x1 performance of a 30mA RCD. If your circuit has tripped the 107 is not the product for you, an insulation / continuity test will help you investigate. A decent PAT tester will also help to investigate any equipment connected to the circuit.
