                  Features:

                  ►Support QC3.0, backward compatible with QC2.0, MTK-PE
                  ►Quickly set the required voltage with the button, no need to dial the switch at all
                  ►Small size, fast measurement
                  ►Press the display voltage and current directly, no other voltage ammeter or load meter is needed
                  ►No need to use QC2.0/QC3.0/MTK-PE mobile phones when testing, protect expensive mobile phones from damage during testing
                  ►Make your product test data more convincing, and guarantee 100% good product shipments
                  ►Players can use DIY to support fast charging devices such as mobile power, router installation
                  ►The entire circuit board consumes a small amount of electricity, and is less than 20 mA in QC2.0/QC3.0 mode.
                  ►Use "high withstand voltage more than 35V LDO"

                  ►Press and hold the switch to power up, switch to USB test mode, test USB voltage and current function
                   

                  Specifications:

                  →Voltage range: DC3.6-32V

                  →Current range: 0.2A-4A (less than 0.2A not displayed)


                  →QC2.0/QC3.0 charger test, no need to connect the load resistance, power-on automatic application for conversion voltage 5V->9V->12V and finally fixed to 12V.

                  →MTK charger test, requires an external load of 10 ohms / 10W, the voltage can be automatically applied to convert to 5V-7V-9V-12V voltage, and fixed at 12V, after the load is taken away, the voltage is restored to 5V.

                  →QC2.0 manual test function, click the manual button to use, used to convert voltage 5V-9V-12V cycle use.

                  →MTK/QC3.0 manual test function, long press button switch for more than 6 seconds to MTK/QC3.0 increase voltage mode, (Note MTK needs external 10 ohm/10W, test Qualcomm QC3.0 does not need external load resistance) Press the voltage once to increase until the voltage is 12V; then press the button switch for more than 6 seconds to switch to MTK/QC3.0 to reduce the voltage mode. (Note that MTK needs to be connected to 10 ohm/10W, and Qualcomm QC3.0 does not need external load. Resistor) is reduced once every time the voltage is pressed until the voltage is 3.6V.

                  Instructions:
                   
                  1.  QC2.0/QC3.0 Test Method
                   
                      > > Insert the tested Qualcomm QC2.0/QC3.0 charger, then the LED shows the current charger voltage value is about 5V, then QC2.0/QC3.0 protocol works, send voltage conversion to the charger Instructions, let the charger convert voltage 5V->9V->12V Finally fixed at 12V does not move, some users use some functions to do 12V power adapter for tablet power supply.
                  >>Manual single-press switch according to the system conversion voltage is 5V-9V-12V.
                  >> First change the voltage to 5V, long press the switch for 6 seconds or more, enter QC3.0 fine adjustment voltage increase mode, press, the voltage of the original voltage plus 0.2V, it is 5.2V, each press, voltage plus 0.2V until the voltage goes to the 12V limit. Press and hold the switch for 6 seconds or more to enter the QC3.0 voltage decrement mode. Each press, the output voltage drops by 0.2V until the voltage drops to 3.6V.
                   
                  Note: Long press of the switch for 6 seconds is a voltage increment and decrement mode conversion.
                   
                  2.  MTK-PE Test Method
                   
                   > > First connect the load resistance of 10 ohms / 10W on the red and black lines of the tester, insert the charger of the tested MTK-PE, then the LED shows the current charger voltage value is about 5V, then the association The MTK-PE protocol works, sending a voltage conversion comman'd to the charger, so that the charger converts the voltage 5V->7V->9V->12V and finally fixes it at 12V. If the load is removed, the charger automatically recovers to the original 5V; Some netizens use some functions to make 12V power adapters for tablet power.
                  >>Manual switch conversion, first connect the load resistance 10 ohm/10W on the red and black lines of the tester, press the switch for 6 seconds or more, enter the MTK-PE voltage increase mode, press, the voltage increases (convert The time is about 2 seconds) each press until the voltage goes to the 12V limit. Press and hold the switch for 6 seconds or more to enter the MTK-PE voltage decrement mode. Each time the output is pressed, the output voltage drops once until the voltage drops to 3.6V.
                   
                  Note that pressing and holding the switch for 6 seconds is a voltage increment and decrement mode conversion.
