Instructions:
1. The first test should be fully charged battery.
2. Connect the battery to be d positive to positive input, a negative input to the negative, can not be red with load reversal may damage the circuit! Load connected to the output of the positive and negative output, to work through the micro USB power supply not available desktop or laptop USB powered, then the battery voltage.
3. Direct start test need only one press of the "OK" on, the can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start fing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing "+" or "-" ons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the "OK "start testing.
4. After the start of the test the will control the load of the electronic switch is turned on, the test data shows that the process will release capacity Ah, current discharge current A and battery voltage V between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the display data stays in capacity Ah and above and the corresponding indicator fes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press "OK" to terminate fing allows stable data display, press again "OK" on to return to the power-on state can just rep the battery test the next section ......
Error codes and their meanings:
Err1: battery voltage is above 15V
Err2: battery voltage is lower than the termination voltage
Err3: Battery can not afford to load or discharge current line too much resistance
Err4: overcurrent current exceeds 3.1A
Note: Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety!
This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals absolute 0V will show 0
Method of use:

1. The battery under test should be fully charged first.

2. Connect the positive electrode of the battery under test to the input positive electrode, and the negative electrode to the input negative electrode. Do not connect the negative electrode with the load, which may damage the circuit. Connect the load to the output positive terminal and output negative terminal, and supply power to the micro USB of the USB power supply of desktop or laptop is not available. The battery voltage is displayed.

3. Directly start the test only need to press the "OK" on, the can automatically set the appropriate stop voltage according to the full charging voltage of the battery, and will f display 3 times before starting the test. To manually set the stop voltage, only press the "+" or "-" on in the battery voltage display state to modify. The stop voltage is displayed at the beginning of P, and the following represents the voltage value, with 0.1V resolution. After setting, press "OK" to start the test.

4. After the test begins, the will switch on the electronic switch to control the load, and the data in the test process will be displayed 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 cuts off the load control switch, and the display data stays on the capacity Ah and fes quickly together with the corresponding indicator light. At this time, the displayed capacity is the actual discharge capacity of the battery. Press "OK" to stop fing and e the data display stable. Press the "OK" on again to restore to the just powered on state you can rep the battery test Next......



Error codes and their meanings:
Err1: The battery voltage is higher than 15V
Err2: The battery voltage is lower than the set stop voltage
Err3: The battery cannot withstand the load discharge current or the line resistance is too high
Err4: Excessive current current exceeds 3.1A
Err5: Improper use or wiring error has caused the device to out and cannot be used current sampling or control switch MOS ed out
