Heres a step-by-step guide on testing your electric fence with a multimeter. When it comes to fencing, there are a lot of options out there. Not all multimeters can now be calibrated in the kilovolt range. All single wire fences ground directly into the soil, but some multi-wire fences also lack a grounding wire. Once youve identified the voltage output, check the resistance levels of the electric fence. There are two things that you are testing for when you use this device: The strength of the current: If it is too low, the livestock wont be able to feel it and they will be able to get close to the fence. You should also check for the continuity of the wires, the resistance of the wires, and short circuits. Switch off the power source, then unlock and open the circuit. Set your multimeter on its highest voltage range, about 6kv, for a more accurate reading.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'dreamoutdoorliving_com-large-mobile-banner-2','ezslot_12',879,'0','0'])};__ez_fad_position('div-gpt-ad-dreamoutdoorliving_com-large-mobile-banner-2-0'); Insert the probe into the required slot and measure the voltage from the fence to the ground. Unless you have turned off the power supply to the electric fence, there is no safe way of touching it without getting shocked. Once the multimeter is set, rotate the dial to VAC and touch the red test lead of the meter to one of the wires of the fence. Some residential use fences may have a low voltage level. Checking for short circuits is an important step when testing an electric fence with a multimeter. Save my name, email, and website in this browser for the next time I comment.

Troubleshooting common electric fence problems using a multimeter, 8. Simply lay the testers tip on a fence wire to obtain a reading. If the reading is zero or close to it, your energizer may be the culprit. Disconnect both the earth and fence cables from the output terminals, then check the voltage by connecting the voltmeter to these terminals. A standard electricians voltmeter or electronic multimeter can be used to measure the current and voltage levels of an electric fence. It is also important to check for shorts in the wires by connecting both leads of the multimeter to one end of a wire and seeing if there is continuity between them. To measure the voltage of the fence wires, you need to set the range of the meter. After powering on the circuit, move to your fences furthest point from the energizer. Point the blinking tip of the non-contact voltmeter toward the fence. Next, take note of the weather conditions.

Anything greater than 8,000 volts is considered more than necessary (some sources say 6,000), and more likely to cause injury according to Storeys article. However, if the right amount of current isnt running through your electric fencing wire, it doesnt appropriately perform its function. If you count the voltage as less than 5000, then you have to look for the causes for the decreased power supply, such as: You can tweak the voltage of your electric fence through the energizer. If you don't notice any arcing immediately, run the screwdriver back and forth over the wire for 10-30 seconds. Otherwise, your body (instead of the meter) will test the electric fence when you touch the other probe end to it! Step #1: Set the appropriate measurement range The first step in electric fence troubleshooting is to determine your measuring range. Following these simple steps will help ensure the proper operation of your electric fence and keep you safe from potential harm.

A standard multimeter is likely to be much more fragile than one that is designed for testing electric fences. Any voltage between 5,000 and 9,000 volts is suitable, but (when dealing with animals and cattle) the best voltage will depend on your cattles species and temperament. Never grasp the wire with your hand. Your solution is to simply replace this energizer. It's also good to have an expert make sure your ground wire is connected properly, as poor grounding is a major cause of electric fence malfunctions. Typical fences produce 6000 to 10000 volts. If resistance is higher than usual, this could indicate a damaged wire or poor connection which would need to be addressed by a professional electrician. Im not only an electrician, but I also like machinery and anything to do with carpentry. Its also important to set the multimeter to the correct setting before testing. To do this, rotate the dial on your multimeter to VAC and touch the red test lead of the multimeter to the positive terminal of the fence controller. Never underestimate the zapping power of an electric fence! The 'best' way to do it would be as follows; Firstly you will need to stand approximately 600mm away from the fence in question with your Multimeter or similar voltage measuring device in hand, switch your device on and set it to DCV 500v, make sure the RED probe is plugged into VmA and BLACK to COM on the device, now carefully place the . The energizer will not be able to reach its full capacity if the ground is not adequately prepared. Low resistance can indicate that there is too much current running through the wire. Save my name, email, and website in this browser for the next time I comment. To test and check for the continuity of the wires along the fence, use a non-contact voltmeter. You may refer to the electric fence manual to find out what type of current is passing through it.

Ensuring that the voltage is within an acceptable range and that there are no shorts or resistance issues will help protect your property and those who may come in contact with it. An electric fence tester is a device that you use to test the voltage of an electric fence. To check the current, Turn off power source and break the circuit. The multimeter will display the values recommended by the supplier if the electrified cable is operating correctly. When an animal touches the fence, it completes a circuit and the current is transferred to the animal, either stunning it or repelling it away from the fence. Corps around the fence may also have a role in reduced volatility, especially in winters with a high level of humidity. This is a crucial step as it helps to ensure that your fence is working effectively.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'dreamoutdoorliving_com-narrow-sky-2','ezslot_23',882,'0','0'])};__ez_fad_position('div-gpt-ad-dreamoutdoorliving_com-narrow-sky-2-0'); To begin, turn on your fence and make sure that it is properly connected to the energizer. Make sure the fence is switched off before you begin testing. They amplify the current and produce high voltage. Plug the fence energizer in and check the fence line voltage with a digital voltmeter. Non-contact voltmeters are very simple tools, but you should always read the product instructions before using one for the first time. This will provide an accurate reading of the voltage at the fence controller.
