parameter:

Power supply voltage: DC4.5-6V (micro USB connector)
Working current: negative 70mA
Discharge voltage: 1.00 V-15.00 V 0.01 V resolution
Termination voltage range: 0.5-11.0 V
Currently supported: 3,000A 0.001A resolution
Maximum voltage measurement error: 1% + 0.02 V
Maximum current measurement error: 1.5% + -0.008A
Maximum battery capacity range: When the screen is less than 10Ah X. XXX, change the decimal point to change the higher value of 9999Ah (1Ah = 1000 mAh), as shown in the figure above, reaching 10Ah XX. XX, and so on.
Board size: 50mm X 37mm
Finished product size: 50mm X mm X 17 37mm (length X width X maximum height position size, including the height of copper feet)

Instructions:
1. The first battery test must be fully charged.
2. Connect the positive terminal of the battery to be tested to the positive input and the negative input to the negative terminal. Do not connect them in reverse (reverse charging will damage the circuit)! Connect the load to the output of the positive and negative outputs to use the tester's micro USB power supply (desktops or laptops cannot use USB power), and then use the battery voltage.
3. Direct test start Just touch the "OK" button, the tester can automatically establish a suitable termination voltage for the fully charged charging voltage of the battery, and it will start blinking 3 times after the test. The termination voltage needs to be developed only when the battery voltage is displayed in an artificial state. The method is to press the "+" or "-" button to modify the termination voltage display beginning with P. After the 0.1 V voltage resolution is represented, press "OK" Button and start the test.
4. After starting the test, the tester will control the charging of the electronic switch to turn on. The test data indicates that the process will release the capacity (Ah), the current discharge current (A) and the battery voltage (V) between the wheels. When the battery voltage reaches the set cut-off voltage, the data shows that the charge control switch outside the tester will remain at capacity (Ah) or higher, and the corresponding indicators will flash together quickly. The actual battery capacity now displayed is a large discharge capacity. When you press "OK" to finish flashing, stable data can be displayed. Press the "OK" button again to return to the power-on state. You only need to replace the battery to test the next section ...

Error code and its meaning:
Err1: Battery voltage is higher than 15 V
Err2: The battery voltage is less than the termination voltage
Err3: The battery cannot withstand large line resistance or current discharge resistance
Err4: Overcurrent (current exceeds 3.1A)
Note: In the process of using resistor discharge, the resistance load will be seriously heated, please pay attention to safety!
The voltage of this circuit is a DC bias specially designed to improve the measurement accuracy. When the terminal displays nothing, a small voltage will not affect the actual measurement. If the input terminal is short-circuited (absolute 0 V), it will display 0
