What is the Best Electric Fence Tester

Electric fencing can be very expensive, especially if you have a large pasture or field that you want fully electrified. Once you have powered your fence with a battery charger, you will want to make sure that the electric fence works and delivers the right amount of blows.

Knowing that your fence is electrified gives you the assurance that your animals are contained and protected.

One thing you do NOT want to do is test the fence by hand and give yourself an unnecessary and potentially dangerous electric shock. The best way to do this is with a special troubleshooter or tester. These handy devices are used similarly to a car diagnostic kit, where you can connect them to the electric fence, and they will indicate any problems or errors.

Tester for Electric Fence - Best Choice

How to choose electric fence tester

How to use an electric fence tester

An electric fence tester is a tool often used by fence owners. It helps to check the faults that occur with electric fences. It also locates any inconsistencies in the current flowing through the wires. This works in the same way as a voltmeter but is specially designed for electric fences. Buying a standard voltmeter will not do the job for you.

Step 1 – Panel testing

You must begin testing both sides by immediately contacting the control board with your Electric Fence Tester to ensure that the unit is effectively sending power from its input and output terminals. These are the locks that go into the control box itself. Make sure that both of them show a reasonable reading to ensure that your control box does not cause any problems, including voltage loss on your fence.

Step 2 – Spot tests

Walk around the perimeter of your fence line using your electric fence tester and run a line check every 10 to 20 meters. This will ensure that your fence does not have a power failure. If you determine that an area 10 to 20 meters away is not displaying a valid measurement, continue and test once more. If you find no issues as you continue, you will need to go back to the final main reading. And check your lines all the more in total to identify the source of your worry.

BUYER’S GUIDE

Voltage

To keep things simple, tension is a form of electromotive energy between two points, and tension is basically how much of this energy and how much of this energy is emitted by your fence wires.

How important are accurate voltage measurements?

It is very important to have an accurate fence tester to ensure that you have the right voltage level for your needs. For example, if you use your fence to keep animals away from your garden, you do not want the voltage to be so high that you kill or damage the animal.

NOTE

An output voltage of 10,000 volts is the maximum voltage permitted by international regulations, so there is no need to buy a fence tester that claims to measure a higher voltage. If your fence tester measurement visually reaches the maximum value at 10,000 volts, this is a warning signal that you are likely to exceed the legal limit and pose a risk to your environment.

Top 5 voltage test points before buying an electric fence tester

  • Always check the output voltage of your electric fence before you buy a fence tester.
  • Make sure that the fence tester is capable of measuring a sufficiently high voltage that matches the voltage of your fence.
  • If it is within your budget, buy a fence tester that measures up to 10,000 volts, even if your fence is only 7,000 volts. This will ensure that you get accurate voltage readings even if you have a surge that exceeds the highest average peak of your fence.
  • A second reason to purchase a fence tester that measures up to 10,000 volts is that some fence testers only measure a range of 600-7000 volts. So if your fence measures over 7000 volts, you will not know if there is a voltage drop unless it is significant enough to fall below 7000 volts.
  • It is ideal to purchase a digital fence tester because it can provide you with more specific incremental voltage readings. The display is also easier to read.

How does a good fault locator or tester for electric fences work?

    Easy screen readings

The display should preferably be wide and bright, making it easy for the eye to see the measurements produced by the tester. Some displays are harder to see than others, some are more difficult to read on very sunny days and some do not feature a backlight that enables you to see the display in poor lighting environments. See the manufacturer’s page for the display dimensions and specifications of every model, or watch a review of each one to get a clearer picture.

    Great usability

A tool must be convenient and easy-to-use, particularly if you need to climb mile-long fences. The device must also be able to keep your hand well away from the electric fence when checking for errors.

    Battery life and easy replacement

Each model has a different battery, some last longer than others. Most troubleshooters you will encounter on the market have replaceable batteries, but some are actually quite difficult to remove and replace. For some models, there are entire videos dedicated to battery replacement. This is not ideal, especially if you do regular tests on your fence. The battery life that each model has can be found on the manufacturer’s site, although it is best to check real user reports to see how long the batteries have actually lasted.

    Weatherproof case

All the models we have examined have a waterproof housing and can easily withstand a little splashing water, but it should be noted that none of these troubleshooters is designed for use underwater or in extreme conditions. One thing you should also pay attention to is a case that, while declaring itself waterproof, creates condensation inside, which makes it much more difficult to read errors on the screen.

Conclusion

These little tools for finding faults on your electric fence are designed to save you time and ultimately help you to identify any existing errors as soon as possible in order to correct them. Although they are costly to purchase and a lot of people are naturally scared off by them, when you have mile-long electric fences on your property, grazing, or ranch, you cannot afford half a live fence. You do not need to take us at our word and purchase any of our top fault-finders, but spare yourself the time and effort and buy one of these devices, you won’t be frustrated!

Frequently Asked Questions

⁉️How to use a fence tester?

When the charger is on, you must touch the positive terminal of the Fence Tester at any point on the electric fence wire. Then you must plug the ground terminal of the Fence Tester into the ground.

⁉️ How do you read a digital electric fence test?

Attach the device to the fence, move it sideways, and insert the probe into the ground to see the visible results on the screen. If the voltage is just below the normal voltage, there is a small error. The voltage drops by about 100 volts every 100 meters as you move towards the error, and then balances out as soon as you pass the error.

⁉️ Can two fence chargers be put on the same fence?

There should not be more than one charger on the same electric fence line. Placing two chargers on the same line will result in damaging both chargers and is a risk to both people and animals that get in touch with the fence.

⁉️ Can an electric fence kill you?

No, an electric fence is no risk. The tension that is passed through the wires is very high, however the current or gain (amperes) is very low. … Amperes are the things that kill. Electric fence generators generate a very high voltage (about 8,000 volts), but very low amperage (about 120 milliamps).

⁉️ May I check an electric fence with a multimeter?

Test your electric fence using a digital voltmeter or a neon fence tester. Fasten it to the fence line, slide it to the side to maintain a proper connection, and put the test probe in the ground. There will be an indicator on the display – on a proper electric fence line it will be over 6,000 volts.
