off. Refer to Boot the main menu as follows::
The main menu consists of three parts: upper, middle and lower. On the upper left is the menu name, and on the
right is the battery level indicator. The bottom edge is the time bar, and the middle is the display and operation
area;
When using the touch screen, you can tap the menu task item directly, and then tap the selected menu task item to
execute. If you are using a keyboard, use the TAB key to toggle the selected menu task item and press Confirm to
execute.
2.2. Single-Cell Test
Attach the test clip to the battery, noting the polarity of the battery (red battery clip to the positive pole of the
battery, black battery clip to the negative pole of the battery).
Select "Single Section Measurement" in the main menu
After entering the single-cell test, select the battery voltage type, battery model, test parameters, and site number
to test. The test interface is shown in the following figure:

Setting interface Testing interface End interface
In the single-cell battery measurement interface, there are three options: "Voltage Type", "Battery Type", and
"Battery Number". It can be set according to the site situation. Standard Internal Resistance is the meter default.
After setting the parameters, click Start Measurement.
Measurement result parameters:
R Battery Ohm Resistor (uΩ)
R2 Battery Polarization Resistor (uΩ)
C2 Electrode Double Layer Capacitor (F)
U Battery Voltage (V)
Click the [Back] button at this time to return to the previous menu. Click the [Re-measure] button, the battery will
be measured again, if the test clip and the battery are not in good contact, the measurement result is very different,
and at this time you can re-measure again. Click the Waveform button to view the battery measurement waveform
graph. Click the [Save] button to save the interface.
Note:
A) The tester will automatically detect if the connection is correct, and if the connection is wrong or not
connected, the tester will prompt "Polarity reversed, check the connection"
B) Battery capacity is based on the average value of the battery internal resistance provided by each
manufacturer in the standard state and the value of the calculation, due to the different battery resistance of
each manufacturer, the battery capacity may be biased, the actual capacity should be corrected according to
the standard battery resistance of each manufacturer.

standard parameters, select a parameter according to the needs, click again to set the parameters, and the main
interface updates the display. After clicking the "Save" button at the bottom of the "String Test" interface, the set
parameters will be saved permanently and the switch will not be lost again, and there is no need to set the
parameters repeatedly, which is convenient for the next test.
