1. Introduzione
The allsun Digital Electrical Fence Voltage Tester EM555 is designed for accurate measurement of pulse voltages on electric fences. It features smart power technology that automatically turns on upon detecting a pulse and turns off after approximately 4 seconds of no pulse detection, conserving battery life. This device is essential for checking voltage levels and identifying faults in electric fence lines, ensuring optimal performance for animal control situations.
2. Informazioni sulla sicurezza
WARNING: Always exercise caution when working with electric fences. High voltage can cause serious injury or death.
- Ensure the electric fence energizer is turned off before any installation or maintenance work on the fence line.
- When using this instrument, always maintain proper insulation. Wear rubber gloves and rubber shoes to prevent electric shock.
- Do not use this device to test voltage greater than 1000V AC.
- Usare cautela con voltages above 30V AC as they are a possible shock hazard.
- This tester is designed for indoor use and should be protected from water, high humidity, and heat.
- The device uses neon lights for indication. In direct sunlight, the neon light may not be very bright. Shade the display to ensure visibility of the flash neon light.
3. Caratteristiche del prodotto
- Campo di misura: 300 volts to 9,900 volts (0.3kV to 9.9kV) pulse voltage.
- Schermo LCD: Large, bright screen for clear voltage level indication.
- Pulsazioni: Detects one pulse every 0.5 seconds to 2 seconds.
- Accensione/spegnimento automatico: Powers on when a pulse is detected and turns off after 4 seconds of inactivity to save battery power.
- Basso consumo energetico: Approximately 0.03W.
- Facile da usare: Simple operation with no buttons or complex setup.
- Design durevole: Suitable for regular fence line maintenance.

6. Istruzioni per l'uso
The allsun EM555 fence tester is designed for simple, three-step operation:
- Ground the Probe: Insert the metal probe into moist soil to complete the circuit. If the soil is too dry, add a suitable amount of water in advance.
- Connect the Hook: Clip the test hook directly onto the electric fence wire. The fence tester will automatically turn on when a pulse is detected.
- Read the Voltage: The display automatically shows the pulse voltage in kV. For more accurate measurement, wait for three pulses to get a stable and accurate voltage reading. The unit displayed is kV (e.g., a display of 6.0 means 6.0kV or 6000V).
After the test hook is removed from the fence, the last reading will be held on the display for about 4 seconds. If the fence tester does not detect any pulse for about 4 seconds, it will turn off automatically to conserve battery.

7. Manutenzione
- Mantenere il dispositivo pulito e asciutto. Pulire con un panno morbido e asciutto.amp panno se necessario.
- Store the tester in its zipper bag when not in use to protect it from dust and damage.
- Rimuovere la batteria se il dispositivo non verrà utilizzato per un periodo prolungato per evitare perdite.
8. Risoluzione Dei Problemi
- No reading on display:
- Controllare che la batteria sia installata correttamente e abbia una carica sufficiente. Sostituirla se necessario.
- Ensure the probe is firmly inserted into moist soil.
- Verify the test hook is making good contact with the electric fence wire.
- Confirm the electric fence energizer is active and producing pulses.
- Display difficult to read in sunlight:
- Shade the display with your hand or body to improve visibility of the neon light indicators.
- Letture imprecise:
- Ensure the soil is adequately moist for proper grounding.
- Wait for at least three pulses to ensure a stable and accurate reading.
