[Latest Upgraded USB C Power Meter Tester]: The multimeter tester can monitor Voltage,Current,Capacity,Electric ,Power,Temperature,Resistance,Charging Time and other data of the USB or type C Port Devices.A Must Gadget checks the charging performance(charging speed and quality) of the output wall/car/solar panel chargers and USB charging cables.It can be also used to find the highest current of the Wireless Charger and test capacity and electric energy of power bank. [Latest Upgraded IPS Color Display Screen]: New upgraded version offers 8 IPS main color screen display interfaces,allowing switching the display interface by pressing the key.With the new interface settings,this instrument can monitor voltage,current,capacity,electric ,power,load impedance,D/D- voltage and other data of USB.(The upgraded IPS HD color screen is clearer than the old LCD color screen.Supports flipping the screen to 180 degree, and 3 kinds of interfaces!) [Professional Safety ]: Featured with over-voltage protection, over-current protection, under-voltage protection, low energy protection and alarm system. This upgraded USB Type C tester can detect safety and maximally the appliances from damaging. It will cut off output automatically and alarm by sound, while it will save data when power off suddenly. [WIDE RANGE OF APPLICATION]: The USB tester comes with A OTG adapter, supports PD3.0/PD2.0, QC3.0/QC2.0 and multiple interfaces,this new multimeter supports the updated 11 Pro mobile phone. (Support 11/X/ Xs quick charging, 29W power, 5V3A / 9V3A / 12V2.5A / 15V2A). It also can be applied to test other type C devices, such as Galaxy S9 Plus, Google ChromeBookPixel, , P9, . Display Screen Operation Manual: Press the Power Button Once:Switch the Display Interface.Long Press the Screen to Flip Fast Double-Click Capacity mAH Clear Fast Press Three-Click Current WH Clear Fast Press Four-Click Time Fast press -click setting full power-off reminder switch and timed charging duration power-off reminder setting flashing In the flashing setting, double-clicking is the -on click is the subtraction, and when adding and subtracting, press and hold for the continuous addend and subtraction; when the short button is pressed to the over-voltage low-voltage over-current setting interface, by quick double-click or fast Three hits are to adjust the value. If electric current exists when it switch no load,please press the button 7 quickly to clear the data of electric current( please do not press the button 7 continually during process of testing.) Please Kindly Note: When the temperature changes or the outside heat conduction to tester causes the current to not return to and the display shows 0.01A or 0.02A or otherwise,Please Hold on the key button then insert to USB Charger It can make the current temperature of the current calibration,After the can more measurements.And when in calibration,the output can not have any load current consumption, so usb tester display 0.00A.
