Function Interface:

Measurement Main Interface           Quick Charge Recognition Interface

Button Instruction:

The button is located on back of the tester. There are 2 ways of operation, long pre and short pre. Short pre is to realize switch between Main Interface and Quick Charge Recognition Interface. Long pre is to realize switch of system setting.

Introduction of Icon Function

1. Pre and hold the button to choose this icon to turn on/off the screen.

2. Pre and hold the button to choose this icon to switch the temperature unit(℃/℉).

3. Pre and hold the button to choose this icon to switch data group.

4. Pre and hold the button to choose this icon to clear data in current data group.

5. Pre and hold the button to choose this icon to rotate the screen.

Operation Instruction:

hold the button and power on the device without load, the current base can be cleared. If you do this with load, the current will always be 0. After the normal power-on, the welcome interface will be displayed first, and then the measurement main interface will be displayed.

15：D-: data negative signal voltage

16：Current quick charge mode display

The product will automatically identify a device with a supported fast charging mode. At this time the device supports the QC2.0、QC3.0、APPLE2.4A/2.1A/1A/0.5A、Android DCP、SAMSUNG. ( Note : D+/D- voltage and quick charge protocol recognition function is for reference only, because mobile phone is updated quickly, it can't be absolutely accurate）

Parameter Setting:

At any interface of 2 interfaces, Pre and hold the button to realize data set. Long pre the button for more than 0.5s, the corresponding icon will be selected and displayed (the background of icon becomes 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, and then loosen the button.

Pre and hold the button, when the corresponding icon is selected and displayed, loosen the button, screen will be turned off, and then pre the button or power on again, the display will light again.

Pre and hold the button, when the corresponding icon is selected and displayed, loosen the button and data group will be switched. This tester can provide 2 groups to store and check, data group 0 and data group 1. When the data set is group 0, the current capacity and energy will be stored after power off. When power on next time, the stored mAh and mWh is blinking displayed. When the new mAh is accumulated up to 1mAh, the stored mAh and mWh will be covered, and the 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, when the corresponding icon is selected and displayed, loosen the button, the data of the current data group will be cleared.

Pre and hold the button, when the corresponding icon is selected and displayed, loosen the button, the screen will be rotated 180 degree, and stored automatically, which is convenient for later using.
