Model: 44669
Introduction
This user manual provides comprehensive instructions for the KERBL Fence Check with LED Display, Model 44669. It covers product overview, setup, operation, maintenance, and troubleshooting. Please read this manual thoroughly before using the device to ensure safe and effective operation.
The KERBL Fence Check is designed for convenient, non-contact measurement of electric fence voltage. It features an LED display for clear voltage indication and a battery status indicator.
Safety Information
- Always handle electrical testing equipment with care.
- Do not attempt to open or modify the device. There are no user-serviceable parts inside.
- Keep the device dry. Exposure to moisture can damage the electronics and pose a safety risk.
- Store the device out of reach of children.
- Ensure the battery is correctly installed before use.
- This device is for testing electric fence voltage only. Do not use it for other purposes.
Product Overview
The KERBL Fence Check is a compact, handheld device designed for quick and easy electric fence voltage testing. It operates wirelessly, eliminating the need for a ground spike.

Components:
- Voltage Indicator LEDs: Four green LEDs indicating voltage levels (2.5 kV, 4.0 kV, 6.0 kV, 8.0 kV).
- Low kV LED: A red LED indicating low voltage.
- Battery Status LED: An LED indicating the battery charge level.
- PUSH Button: Activates the measurement function.
- Battery Compartment: Located on the back (not visible in Figure 1).
Setup
Battery Installation:
- Locate the battery compartment cover on the back of the device.
- Carefully slide or unclip the cover to open it.
- Insert one 9-volt block battery, ensuring correct polarity (+ and -). The device comes with a 9-volt block battery included.
- Replace the battery compartment cover securely.
- After battery installation, the battery status LED should briefly illuminate, indicating sufficient power. If it does not, check battery orientation or replace the battery.
Operating Instructions
The KERBL Fence Check allows for quick and easy voltage measurement without direct contact or a ground spike.
Performing a Measurement:
- Hold the device firmly in your hand.
- Approach the electric fence wire or tape. The measurement is carried out at a distance of maximum 0 - 5 cm from the fence.
- Press and hold the 'PUSH' button on the front of the device.
- Observe the LED indicators. The voltage is displayed by four bright green diodes in four levels: 2500 volts, 4000 volts, 6000 volts, and 8000 volts.
- If the voltage is low, a red LED will illuminate, indicating a potential issue with the fence's power.
- Release the 'PUSH' button once the reading is taken.

Understanding the Display:
- Green LEDs (2.5 kV, 4.0 kV, 6.0 kV, 8.0 kV): Each illuminated green LED indicates that the fence voltage has reached or exceeded that specific level. For example, if the 6.0 kV LED is lit, the voltage is at least 6000 volts.
- Red LED (Low kV): If this LED illuminates, the fence voltage is below the optimal operating range, indicating a need for inspection or repair of the fence system.
- Battery Status LED: This LED indicates the remaining battery life. If it flashes or remains off during operation, the battery may need replacement.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace the 9-volt battery when the battery status LED indicates low power or when the device fails to power on. Refer to the "Battery Installation" section for instructions.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed battery. | Check battery polarity; replace battery. |
| No LED indication when testing. | Device too far from fence; fence has no voltage; battery low. | Ensure device is within 0-5 cm of fence; check fence energizer; replace battery. |
| Only "Low kV" red LED illuminates. | Fence voltage is too low. | Inspect fence energizer, connections, and fence line for faults or shorts. |
| Battery status LED indicates low power. | Battery is depleted. | Replace the 9-volt battery. |
