Features
It can be used for automobile fuse testing, electric frequency voltage testing, generator testing, and circuit positive and negative pole identification. The green light flashes when the clip clamps the positive test line. The red light lights up when the clip clamps the negative test line.
Applicable to circuit maintenance of various models. 3V6V12V24V 48V general automobiles/trucks/motorcycles/electric vehicles/construction machinery, etc.The tester can be used to test the low-voltage circuit fault, voltage and power failure test of the car.
Strong spring inside the tube. The pen has a strong spring design with better sensitivity. The external alligator clip is easy to clamp, freeing your hands, convenient and fast.Auto Voltage range detected and LED display, you can diagnose quickly and significantly improve work efficiency.
Coil spring wire. The coil spring wire design is adopted, which is convenient for storage and quick to use. Pen tip design. The needle design has more sensitive and better effect.
Spring wire digital display electric pen. When using the electric pen to measure electricity, it is necessary to measure intermittently and use the touch method. The power should not exceed 3 seconds to avoid too long power-on time to prevent the circuit board from burning! The loss caused by improper use shall be borne by yourself!
