This USB tester not only compatible with Type-C pd quick charging protocol power 45W and iphone 87W smart charger PD power supply such as mobile power, but also compatible with Qualcomm QC2.0 (5V / 9V / 12V / 20V) Qualcomm QC3.0 (3.8 ~ 12V +/- 0.2 step), Android BC1.2 (5V), Apple iPhone5V / 2.4A and MTK-PE (5V / 7V / 9V / 12V) Qualcomm quick charge protocol voltage Range of charge-through measurement. And USB internal data line before and after the through mode, it can also be compatible with U disk readings and computer USB interface data transfer voltage and current measurement applications, the use of a more extensive range of USB interface can be used.

The engineer once again has several technical upgrades:
1) USB-C male head replacement cost of copper pin contact plug better, tighter current data more reliable.
2) increase the screen 180 degrees flip display settings function, to adapt to some chargers using inverted display as a positive display (click to AAA interface, and then double-click the key to make it 180 degrees reverse display).
3) the optimized PD protocol is suitable for Apple's 87W charger, and both the positive and negative side can transmit the ACC pin of the PD protocol.
4) the OTG protocol of Type-C can open the OTG digital function by inserting a random embedded Android switch head in the upper left corner of Android line.
5) increase the interface settings such as overvoltage, low voltage, overcurrent, backlight time, etc., and switch to the corresponding interface at the short button at the front desk, set up by adding double or three strokes.
6) challenge limit by metal industry upgrade patch manganin sampling device reduces the resistance to <1mR, access after use almost does not affect the charging speed, the perfect support for HUAWEI 4.5A super fast charging current, like a data line, the more coarse the more shorter the better, faster charging
7) increase the zero position calibration function of the product front desk, and measure the ultra small current more accurately. When no load is pressed, the key is quickly pressed 7 times. It is the zero temperature accurate calibration of the current temperature environment. At that moment, the accuracy of measurement is improved again. This is another innovative design that we have learned from U table technology experience for many years.
8) the built-in PD protocol can open the Type-C interface with the PD protocol's intelligent charger unloaded power output display, so as to facilitate aging and testing. (this function can be successfully opened by inserting the random Android OTG adapter head in the upper left corner of the cross U table with the Micro USB line input port).
9) the PD protocol quick charging mode measurement that supports the updated apple X mobile phone. (support iphone 8 / 8P / apple X / MacBook quick charging, 29W power, 5V3A / 9V3A / 12V2.5A / 15V2A)
10) optimize the number of transmission functions, such as power failure memory, USB data transmission, PD fast charge protocol and so on
