The product will automatically identify a device with a supported fast charging mode. At this time the device supports the QC2.0、QC3.0、2.4A/2.1A/ 1A/0.5A、Android DCP、SAMSUNG.( Note : This quick charge agreement recognition model is for reference only, because cell phone updated quickly, it can\'t be absolutely accurate identification ）

Parameter Setting:

At any interface of 2 interfaces, Pre and hold the button to realize data set. Long pre the button more than 0.5s, the corresponding icon will be selected and displayed (the background of icon turn black to blue), then step through the options of screen off, temperature display units, data group switch, data group clear zero and screen rotation. Stop on the function you wish to set then lo the button

Pre and hold the button, the corresponding 1 icon will be selected and displayed, then lo the button, screen will be off, then pre the button or power on again, the display will light again

Pre and hold the button, the corresponding 2 icon will be selected and displayed, then lo the button, the temperature unit will be switched. Degree centigrade is the default temperature unit

Pre and hold the button, the corresponding 3 icon will be selected and displayed, then lo the button, data group will be switched. This tester can provide 2 groups to store and check, 0 and 1 data group. When the data set is 0 group, the current capacity will be stored after power off. When power on next time, the stored mAh and mWh is blinking displayed. When the new mAh is up to 1 mAh, the stored mAh and mWh will be covered, andthe values will start over. When data set is group 1, the current capacity will be stored after power off. And the stored capacity will be accumulated after power on.

Pre and hold the button, the corresponding 4 icon will be selected and displayed, then lo the button, the data of the current data group will be zero.

Pre and hold the button, the corresponding 5 icon will be selected and displayed, then lo the button, the screen will be rotated 180 degree, and stored automatically, which is convenient forlaterusing
