Features:
1. Automatic calibration of current zero function
After long-term use, due to aging of the
device or changes in ambient temperature, small current measurement
errors may increase. The solution is to hold down the button and the
breathing light is on, and an automatic calibration current zero
operation is performed.
After entering the main interface, the
first line displays the current voltage value, the current power and the
current data group, and the second line displays the current current
and the cumulative capacity respectively.
2. Overvoltage and undervoltage reminder function
When the voltage is higher than 5.3V, it
will be displayed on the screen and will flash continuously, indicating
that the USB voltage is too high. When the voltage is lower than 4.7V,
it will be displayed on the screen, and it will flash continuously,
indicating that the voltage is too low, the flashing cannot be turned
off, when the voltage is normal. The range disappears automatically.
3. Capacity automatic storage function
In the main interface, if you click the
back button, you can cycle through the next set of data, the tester can
provide 0-9 a total of 10 sets of data to save and view.
When the data group is 1-9 groups, the
current capacity is stored when the power is turned off, and continues
to be accumulated when the power is turned on next time. When the data
group is 0 group, the current capacity is stored when the power is
turned off, and the next time the power is turned on to remind the last
capacity, but When the accumulated capacity exceeds 1MAH, the last data
is automatically cleared and re-accumulation begins.
In the main interface, double-click the
back button (within 0.5 seconds between two presses) to enter the data
viewing interface. The secondary interface displays the cumulative
capacity of the current data group. In this interface, click the back
button to view in turn. The next set of data.
In the data viewing interface, if you
press and hold the back button for more than 2 seconds, you can clear
the data in this group. If you double-click the button, you will exit to
the main interface.
4. Capacity unit switching function
In the main interface, press and hold
the back button for 2 seconds, release the breather light when it is
lit, and switch between mah and mwh.
5. Screen flip function
In the main interface, press and hold
the back button for 4 seconds, the breathing light will be on when it is
turned on and off, and the screen can be flipped and automatically
memorized for later use.
6. Screen off function
In the main interface, long press the
back button for more than 6 seconds to release, you can turn off the
screen display and enter the power saving mode. At this time, the
breathing light flashes, click the button to return to the main
interface.
