Some types of fencing ground directly into the earth instead of using a ground wire. By catching any issues early on, you can prevent costly repairs or replacements further down the line. Im not only an electrician, but I also like machinery and anything to do with carpentry. The procedure is as simple as that, but we will describe each step further for proper understanding. Can I Use a Standard Multimeter for Testing an Electric Fence? If you have an electric fence, it's definitely worth the $30-$50 USD investment. You should see a reading indicating the voltage output of the electric fence.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'dreamoutdoorliving_com-large-mobile-banner-1','ezslot_9',877,'0','0'])};__ez_fad_position('div-gpt-ad-dreamoutdoorliving_com-large-mobile-banner-1-0'); But dont stop there its also important to check the resistance levels of the electric fence. Touch the black lead of the meter to a ground wire or stake, and observe the reading that appears on the display. Never urinate on an electric fence as the current can travel up the stream of urine and shock you. STEP 4 - Test: Check the voltage output with your voltage tester. Next, you will connect the end of the metal legs of the multimeter to the twisted wire ends of your underground fence system. With a multimeter, you can measure current, voltage, resistance, and many more to check for the continuity of the wires, the resistance of the wires, short circuits, and other issues that might arise when installing or maintaining an electric fence. First, set your multimeter to the kilovolts (kV) range and ground the negative probe. If grounding isn't the problem with your fence, contact the fence manufacturer or an electrician for assistance. When vegetation is wet or a piece of metal is grounding the fence wire, there could be a voltage leak. First make sure that the multimeter is turned off.2.
