An electric fence tester with indicator LED lights is a crucial tool for electric fence owners. It helps ensure the fence is functioning properly and detects any weak areas that require attention. The tester has LED lights that indicate if the fence is live and can identify low voltage conditions. It is suitable for fences with electric currents ranging from 300V to 10kV, making it versatile for different types of fences. To use the tester, you connect it to the fence, observe the LED lights . troubleshoot and repair any issues, and retest the fence to ensure it is working optimally. Safety precautions and consulting professionals are important when dealing with electric fences.
