Non-Contact AC Voltage Tester：
Practical and Convenient Tool to Test Electrical Lines, Accurately Detects AC Voltage Ranging from 12V to 1000V
Good Safety Tool：
Great tool for diagnosing AC voltage. A must have for those do it yourselfers and troubleshooting electrical issues.
This is a great tool for the home owner, should be one in every tool box.
Press the power key and keep up for more than 1 second. The bee buzzed, the screen lit up and entered the test state. When the power on, power key was pressed and the bee turned to shut down.
Safely Sound & Light Alarm:
Voltage frequency can be distinguished by beep and LED indicator. It's loud enough to hear over moderate machine equipment noise. When it senses the voltage around, it start beeping, even though the tester pen hasn't touched the item. As more closer, it beeps stronger. Small in size, easy to store in tool box or carry in your pocket.
Please mind before using:
When detect the same null wire, why sometimes the beep sound’s frequency and the number of the grids on the LCD is different?
If the live and null wire are too close, the tester pen will still beep quickly than normal when it detects null wire, this is because the live wire is too close that cause the pen detect its strong voltage.
This also explains why sometimes all the sockets of outlet will beep at the same speed when detects the outlet. When detect the live/null wires, better apart the two wires to a certain distant.
