For your purchase, get a voltage tester specifically designed for reading the energy from an electric fence. Unlike other voltage meters, fence testers are designed for easy use on electic fencing. GK503C Neon Fence Tester The neon lamp tester for fence uses neon lamps to indicate voltage produce on a fence line or by a fence controller. It is designed for low impedance and standard duty fence controller. Specifications Model： GK503C Testing Range: 200V-9000V Display Type: Neon Lamp Material: ABS Size: 1.8 * 4* 0.63 inches Weight: 2.4oz Wire Length: 59.8inches (+/-3%) Operating Environment: 0℃ to 40℃ Relative humidity< 80% Storage Environment: -20℃ to 50℃ , Relative humidity< 85% How To Use? Insert the probe in ground using the insulated grip . Attaching the test hook to wire fence. To avoid electric shock, do not touch any conductor (such as the test hook, the fence). The neon lamps light to indicate the voltage. If no neon lamp lights, the cause may be one of the following: The probe or test hook’s connection is loos. The fence has electrical problems.
