This item is USB charging current, voltage, discharge capacity , intelligent device. With this device , can be very easy to find digital devices charging problem.

 

Performance parameters :

1, input voltage : 3V-7V

2 , the input current : <3.5A

3 , the display : voltage, current, discharge capacity ( total of 10 groups can be stored )

4 , the data function:

5, the data calibration function

Data calibration function settings ( factory have been adjusted, if you feel not allowed to self calibrate the following way ) : an electronic load device, a constant current source .

Constant current source and transferred to 8.5V or less than 10V (recommended 9V), electronic load is set to CC mode ( constant current mode ) 3A, 2A, 1A, 0.3A , respectively, the four current calibration . To 3A as an example:

When 3A calibration: electronic load setting the constant current mode 3A, LCD fuel gauge will automatically slow the current calibration ( about 10S) can see the current will change the LCD screen , turn off the electronic load calibration data is automatically protected.

6, the data is cleared : Hold down the button until after ( the first of several sets of data ) becomes the next set release button , automatically skip to the next set of data from scratch.

7 , View : Double-click the button (0.5S or less ) , enter to view the data view mode , then the backlight LED will flash , and then click the button to display the next set of data , several groups so check back . Double-click to exit View mode , backlight LED grow lights .

8, the voltage is high or low : Arrow LCD backlight LED flashes prompt. Press the button LED lit 30S.

9 , power status :

By MicroUSB cable or USB cable tester comes with male power , the LCD screen will display the entire contents of about 1 second ( detection LCD screen stroke segment is intact ) , and then displays the last data ( capacity, and third sets of data ) , high or low Tip voltage, current and voltage current
