Is it complicated?** A: Drive the probe into moist soil, clip the test hook to the fence wire, and read the voltage (kV) on the LCD. Powers on/off automatically. **Q: What is the voltage measurement range?** A: The allsun EM555 can accurately measure pulse voltages from 300V up to 9.9kV (9900 volts), covering the output of most standard agricultural electric fence energizers. **Q: How does the "Smart Power" feature save battery?** A: The Smart Power technology means the tester automatically wakes up when it detects a pulse and shuts down after about 4 seconds of inactivity. This prevents battery drain if you forget to turn it off. **Q: The display reads 5.5. What does that mean?** A: A reading of 5.5 means your fence voltage is 5.5 kilovolts (kV), or 5,500 volts. For the most stable reading, we recommend noting the value after the tester has detected three consecutive pulses. **Q: Is it safe to use this tester?** A: Yes. Safety features include a finger guard and an insulated probe. Always drive the probe into moist soil for a proper ground and wear rubber-soled shoes during use for added safety. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***. on 21 February 2022* Very easy and simple to use ### ⭐ Review *by S***O on 3 October 2024* Testeur très pratique mais malheureusement il n'est pas étalonné, donc pas fiable. ### ⭐⭐⭐⭐⭐ Review *by D***S on 29 April 2024* Very simple and easy to use ## Frequently Bought Together - allsun Electric Fence Tester Digital Electric Tester High Voltage for Electric Fencing 300-9900V - Solar Powered Electric Fence Energiser X-Stop 0040 2 Km Range Full Kit Includes Earth Stake and All Leads Plus USB Charge Cable For Horses and Other Animals - DOBLIT Poly Wire Electric Fencing Conductor Wire 6 Strand 9 Strand Multi-Colour Paddock Electric Fencing Cattle Sheep Horse Pets Crop Protection Pest Deterrent (Blue and White 6-Strand 500m) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/362093202-allsun-digital-electrical-fence-voltage-r-electric-fence-fault-finder](https://www.desertcart.us/products/362093202-allsun-digital-electrical-fence-voltage-r-electric-fence-fault-finder) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-10*
