Test of mobile power supply capacity of power method and skill:

The charging treasure the electricity first, and then plug in the table, the capacity of power

through the button to reset, and then plug in the electronic load on the connection diagram

or cell phone to charge treasure to discharge, until the rechargeable battery, it is again

electrify can read into the total capacity and the power value, this is the charge of capacity

and power about value, because it is the internal power off memory function, so it can be a

complete discharge, discharge process can also be multiple discharge, check again until after

the treasure to battery charging capacity value.

Test the charger of the maximum output current method:

Connected in figure 1, change the load size make current increase voltage is reduced to the

charger nominal voltage instantaneous, when the current value is the charger can output the

maximum current value; To change the load to the charger aged 2 ~ 6 hours, nominal

current value of discharge current voltage stability in the process of aging, the temperature

of the charger is less than 50 degrees or so, explain this charger nominal current realistic, no

empty mark, can satisfy the charging speed, on the contrary, if the voltage is reduced,

current value difference is too big or too hot, even U watch alarm flashing and no output,

measured charger belong to the current standard, quality inferior performance, this method

also adapt to all USB output current test methods.

Tip :

some users of the failure to understand the current nominal value is the output of the charger when

the maximum load of the maximum output current value, is not for mobile phone charging current value,

so the different load current value, actual should follow ohm's law to calculate the current value, and in the

devices such as mobile phone, mobile phone in different status and at different times of the charging

electric current curve is fluctuation change, U table only show the actual flow of current value, is not part

of the user see U table testing is not the same as the display value and the nominal current value will doubt

U table shows the accuracy of current measurement.

Test the USB of voltage, current, power, power, current time

Warm prompt: this time show U table refers to > 0.5 W power do timing calculation, if < 0.5 W,

the system do not calculate time accumulated, only in this way can judge charging time,

please know.

Connection after electrify to drawing, can be displayed real-time monitoring through

the USB line power battery capacity and voltage current flows through the current

accumulation of information such as time, in the process of electricity through the

short button press screen switching, long press the screen rotation, rapid

double-clicking capacity mAH, three quick blow power Wh, four quick blow zero time,

five quick blow capacity battery time all reset at a time.

1) short button press is conversion screen

2) the rapid double-clicking capacity reset reset (mAh)

3) three quick blow power reset reset (Wh)

4) four quick blow is timing reset reset (00:00:00),

5) five quick blow is Transform storage number(NO.01~10)

6) all keys according to the capacity, power, long time reset reset(mAh, Wh, 00:00:00)

7) when the screen rotation interface button long-press flip the screen

8) when the black screen interface button long-press is into the background mode

Tips: When the ambient temperature changes or the outside heat conduction to tester

causes the current to not return to zero and the display shows 0.01A or 0.02A or

otherwise,Please when operating at close to the screen, then long button press is

to enter the background model, and then short button press into the second section,

the output does not connect any load, and then put the reset button long-press is

current, to ensure that can in no-load current in 0.00 A more precise measurement
