Requires 9 Volt Battery Operation (Not Included), Not waterproof How to Use the Electric Fence Voltage Tester: The shower proof electric fence tester for electric fence use neon lamps to indicate voltage produce on a fence line or by a fence controller.It si designed for low inpendanceand standard duty fence controller. Many horse lovers and ranchers employ electrifield pasture fences to confine their livestock.An electric pasture fence is designed to deliver a non-lethal shock to an animal. It is actually a form of protection for horses and cattle .Better for them to be started by a sudden electric joit than to wander onto a highway and be killed. To be certain that an electrifield fence is doing its jobit must be tested periodically to make sure that there are no breaks in the wire and that the voltage level is high enough. Operation Instruction 1.Drive the probe into the moist soil. (If the soil is too dry add a suitable amount of water to the soil in advance.) 2.Connect the test hook to the fence line. 3.The fence tester will turn on when a pulse is defected. 4.If further pulses are detected the voltage will be displayed. For more accurate measurement result read the display after three pulses have been detected. Note: Reading's unit is kV. For example if the display reads 6.0 the voltage value is 6.0 kV. 5.After the test hook is removed from the fence the last reading will be held on the display for about 4 seconds. It will turn off automatically in 4s when no pulse. Provide you have the proper equipmentit'sa relatively easy chore to ! Step1: Apply power to the fence by tyrning on the fence . Step2: Insert the bare mental grounding probe into the soil. It is attached to the voltage tester. Step3: Hang the voltage tester on the fence wire . Step4: Observe the voltage level indicated on the fence tester.
