Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si USB multi-function screen four high-precision tester - Adopt 12800 pixel IPS LCD screen. General test of USB digital devices, support Qualcomm QC3.0/2.0/MTK-PE fast charging voltage. A of parameters on one screen display, real-time monitoring of charging voltage, current, power, capacity, power, timing, temperature (Celsius/Fahrenheit, etc.) Real-time monitoring of the charging status of data Cable - U96 USB color tester can monitor the charging data of the mobile phone in real time, supporting QC3.0 (3.8-12V, -/+0.2 step). Support QC2.0 (5V9V12V20V), Android BC1.2 (5V), 5V2.4A and MTK-PE (5V/7V/9V/12V). Wait for the fast charging voltage range to charge! Smart repair hardware, poor software calibration technology - Press and hold the USB tester button when no power is on, and insert the USB charger to enter the background calibration mode. Press the button shortly to switch to the corresponding calibration function, long press to confirm the corresponding calibration function! (Tips:This calibration must use 5V standard voltage and 2A constant current power supply, no misoperation is allowed.) Support for super fast charge detection - Support fast charge detections such as for /for /for /for , DCP (9V2A), SCP (4.5V5A). Super flash charging 4.5V5A, for /for Qualcomm 5V9V12V and other fast charging protocols Color screen display on/off function - By pressing the button to switch the interface to the information screen to turn off the display, you can also charge the device normally! Click the button to wake up the display again; General test USB chargers - Through the constant current load, you can test whether the voltage and current power of its charger meet the nominal value.
