LW21 Longruner Multi-Function Tester with 3.5inch Colorful D
For detecting NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery, resistor and capacitor and other components, etc.
Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly. ( Use 12864 liquid crystal display with green backlight)
After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.
Measurement results represent by TFT graphic display(160x128). Support Chinese and English.One key operation, Auto Power Off(Timeout Settable). Can also press the multi-functional button to close the detector.
If the test is black for a while, it may be that the power is not enough, and only if it is full again, it can continue to be used. To protect the tester during charging, work can only continue when the green light is on. If you have any problems with use, please feel free to contact us!
