Working power:DC 5V(TYPE-C Input) Working current:10-20MA Model :UD11A03 (compatible with DT3) Weight:12.7g Instruction of The Tester: 1. Use the Type-c charging cable to plug into the Power-IN interface to supply power to the PCB board. 2. Insert one end of the data cable to be tested into the corresponding input port, and the other end into the corresponding output port. 3. Observe the indicator light. Indicator light description: 1 D+, D-, VCC, GND indicator lights are on, indicating that the data line has data transmission function. Notice: During the test, except for the Power-IN port, the input and output ports of the test data line, other ports cannot be connected to the data line, otherwise the test result will be affected. Colour:Black Material:PCB+Metal Package Contents: 1 * USB Cable Tester Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Quickly detect data line anomalies. Quick detection of data line on and off: the light is on when the power is normal, and when the light is off, the power is abnormal. If VCC or GND is not lit, it indicates that the charging function of the data line is abnormal. D+ or D- is off, indicating that the data transmission function is abnormal. All 4 indicator lights are on, then the data line is normal (double- type-c data line requires all 5 indicator lights to be on). CC is dedicated to double- type-c data line detection. When testing other data lines, the light will not turn on. The detection board is small, light and easy to carry.
