F1100 Voltage Tester Pen | Professional Electrical Test Pen for Voltage Detection

F1100 Voltage Tester Pen – Enhanced Features and Functionality

• Test Mode Activation: Once the F1100 Voltage Tester Pen enters test mode, the LED indicator flashes twice every 1.5 seconds, signaling that the device is ready for voltage detection.

• AC Voltage Detection: To detect AC voltage, simply bring the tester's probe near a device or object with live AC voltage. The LED indicator will flash, and an audible beep will sound, providing a clear indication of voltage presence.

• Low Battery Warning: If the battery voltage drops below 2V, both the LED display and testing functionality will deactivate, ensuring that testing is not performed with insufficient power. When in this state, the tester will not light up during operation or testing.

This voltage test pen is designed for safe and accurate electrical testing, perfect for professionals and DIY enthusiasts. It provides real-time voltage feedback and clear error notifications, making it a reliable tool for voltage detection in electrical systems.
