When the value is large,
Display as X.XXX when below 10Ah,
Reaching above 10Ah is shown as XX.XX, and so on.

Circuit board size: 50mmX37mm

Finished product size: 50mmX37mmX17mm

(long X width X height, including copper foot height)

Weight of plate and accessories: plate 28g plate (including copper column),

two 5W ceramic resistance 9g, 50W resistance about 30g (including wire)

Note: In order to improve the accuracy of the voltage measurement,DC bias,

A small voltage displays when the terminal connects nothing,

Does not affect the actual measurement,

If you short connect the input terminal(Then 0V) shows 0.

If you want to understand the principle,

you can go to the superposition theorem in electroengineering.

Usage method:

1. The tested battery shall be fully charged first.

2. Connect the positive electrode of the tested battery to the positive input,

Negative to input negative, unconnected reverse

(with load connected reverse may damage the circuit)!!!

Connect the load to the output positive electrode and the output negative electrode,

give the tester micro USB a working power supply

(no desktop or laptop USB power supply), and then display the battery voltage.

3. Direct start the test only requires pressing the "OK" button.

The tester can automatically set the appropriate termination voltage according

to the full battery charge voltage, and will flash for three times before starting the test.

The termination voltage needs to be determined manually.

You only press "+" or "-" button under the battery voltage display state.

The termination voltage starts with P, represents the voltage value,

and the resolution is 0.1V. After setting, press "OK" to start the test.

4. After the test starts, the tester will turn the electronic switch on to control the load.

The test process data shows that the wheel will appear between the release capacity (Ah),

the current discharge current (A) and the battery voltage (V).

When the battery voltage reaches the set termination voltage,

the tester cuts off the load control switch,

displays the data stays above the capacity (Ah)

and flashes quickly with the corresponding indicator,

The capacity displayed at this time is the actual discharge capacity of the battery,

press the "OK" can stop the flicker to stabilize the data display,

press the "OK" button again to restore to the just

on the power state can replace the battery test next section...
