Press for two seconds, tester sounds DD, then turn off. When no electric field signal is detected, the tester is with green LED, it will automatically turn off in 5 minutes.

2. When detects voltage, tester tip sounds with red LED; when electric field becomes stronger, the tester is with faster sound.

3. Detect radiation intensity of electric field. When detects radiation, tester tip LED changes from green to red, and sounds

4. Breakpoint detect: two sides of the breakpoint have different radiation intensity, the difference can make tester emit different frequency sound. With an obvious sound difference, user can find the breakpoint location. (Prerequisite: the line with breakpoint must be located on wire line, test along the surface of the line.)
