USB voltage current Tester, Real time Monitoring, Dual display, Precise Calibration, Battery Capacity Measurement

Product description Feature*Safety charging, real-time monitoring and mastering your charging teaching, dual-display USB current voltage detection table, and display voltage current data at the same time, convenient to view, USB male head in 5V charger,female socket -in mobile phone and other equipment, read the voltage directly to read out the voltage Current parameter*You can detect USB line quality, with for current calibration function, and higher current accuracy. Data calibration function setting, an electronic loader, a constant current source. The Hengliu source is adjusted to 10V and 10V or less(recommended 9V), and the electronic load is set to CC mode(Hengliu mode) 3A, 2A, 1A, and 0.3A.*Measure the battery capacity, and use the linear charging circuit to fill the battery with no power to be fully powered through this capacity table. The capacity reading is the battery capacity. Using this can also measure the charging capacity of the mobile phone, and even calculate the mobile phone charging efficiency.*Measure the output capacity and efficiency of the mobile power, begin connect the mobile power supply, turn on the mobile power supply, and press the key until the capacity data is for zero. in the mobile phone and charge until the mobile power supply is of charge. The display capacity when the machine is turned on next time is the MAH output of the mobile power. Note that this MAH is far smaller than the nominal MAH, the output MAH*output voltage 5V/battery MAH*battery voltage 3.7V= mobile power efficiency*The data is cleared, and the button is held until the(several sets of data) becomes the next group. After the button is released, it will automatically jump to the next set of data from scratch.SpecificationProduct Name: KWS-10VASize: 60mm(even USB74mm)*width 28mm*height 15mmVoltage: Input/output voltage 3V-9V, voltage resolution: 0.01VCurrent: input/output current: 0A-5A(seeing the scope of the intention of 0-3A, current resolution: 0.01AAccuracy: positive and negative 1%Line loss: about 0.1 EuroCommunication: YesWeight: 22gPackage included1*USB voltage current Tester Manufacturer Contact Information no
