The Gallagher Fault finder, is an advanced measuring instrument with which you can measure both the voltage (0.2 to 15 kV) and the current (1–99 A) of your fence, as well as the energiser and earthing. In addition to measuring voltage and locating faults, the device provides direct insight into the condition of your fence.

Simple measurement without separate earth stakeThe device works with a measurement slot and a built-in earthing function. To test the wire, you do not need to use the earth stake: just place your thumb on the grounding pin of the device and you provide the earthing yourself, without risk of a shock. Measure the voltage by placing the wire in the measurement slot. For measuring the earthing or the energiser, you do use the earth stake and the pin (in the measurement slot), which you can easily unfold and place against the energiser or earth stake.

Current arrow points directly to the faultWhen detecting faults, the Fault finder indicates the current direction via an arrow on the screen. This current direction always goes towards the fault. You take measurements at intervals of 50 to 100 metres. A sudden drop in current between two measurement points indicates a fault, making it easy to isolate and solve problems. The arrow is only visible in case of larger faults.
