Combination digital voltmeter and current meter used to quickly locate faults on electric fence. Large LCD screen displays fence voltage, amps, and direction of fault. Use fault finder functions with any brand of pulse energizer. Impact and water resistant case with integrated belt clip. Large LCD screen displays fence voltage, amps, and direction of fault Use fault finder functions with any brand of pulse energizer Cordless design no ground probe required Impact and water resistant case with integrated belt clip Low battery warning system Works with all brands of energizers 9V battery sold separately. Two ways to use the fault finder, depending on the type of fence: Type 1: Non-Looping Fence On a fence with no faults, the current will slowly decrease as you get farther away from energizer The current on the fault finder will rapidly drop if there is a fault on the fence If a drastic drop occurs, you can use the fault finder to go back on the fence to determine the exact location of the fault. Type 2: Fence Loops Back To Energizer The fault finder will point in the direction of the fault When you pass the fault, the direction of the current will change When this occurs, you can go back on the fence to find the exact point where the current changes direction to find the fault.
