2. When the value is large, it is switched by decimal point shift. When it is less than 10Ah, it will be displayed as X.XXX, when it reaches more than 10Ah, it will be displayed as XX.XX, and so on.
3. Circuit board size: 50mmX37mm
4. Finished product size: 50mmX37mmX17mm (Length X Width X Height, including copper foot height)
5. Weight of board and accessories: single board 28g (including copper pillar), two 5W ceramic resistors 9g, 50W resistor about 27g (including wire)
6. Note: In order to improve the voltage measurement accuracy, this circuit is specially designed with DC bias. When the terminal is connected nothing, a small voltage will be displayed, which does not affect the actual measurement. 0V) will display 0. If you want to understand the principle, you can check the superposition theorem in electrical engineering.
7. How to use:
- The battery under test should be fully charged first.
- Connect the positive pole of the battery under test to the input positive pole, and the negative pole to the negative pole of the input. Connect the load to the output positive pole and the output negative pole, and connect the tester micro USB with working power (not available for desktop or notebook USB power supply). The battery voltage is displayed at this time.
- To start the test directly, just press the “OK” button, the tester can automatically formulate a suitable termination voltage according to the full charge voltage of the battery, and will flash the display 3 times to start the test. Need to manually set the termination voltage, just press the "+" or "-" button to modify in the battery voltage display state, the termination voltage is displayed at the beginning of P, the back represents the voltage value, the resolution is 0.1V, after setting, press "OK" "start testing.
- After the test starts, the tester will turn on the electronic switch that controls the load. The test process data display will be displayed between the discharge 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, the display data stays above the capacity (Ah) and flashes quickly with the corresponding indicator light, the displayed capacity is the actual discharge capacity of the battery, press it "OK" can stop the flashing and let the data display stably. Press the "OK" button again to restore to the state of just powering up and replace the battery to test the next section ...
8. Error code and meaning:
- Err1: The battery voltage is higher than 15V
- Err2: The battery voltage is lower than the set termination voltage
- Err3: The battery cannot bear the load discharge current or the line internal resistance is too large
- Err4: Current is too large (current exceeds 3.1A)
- Err5: Improper use or wiring error has caused the device to burn down and cannot be used (current sampling or control switch MOS burned)
9. Note: If the battery is reversed, when the load is turned on and the load current is large (about> 0.8A), the circuit switch tube may be damaged!
10. Secondary calibration operation: Press and hold three buttons to power on the tester at the same time, enter the calibration mode, first display the number of calibration records, then enter the formal calibration sampling program to display 0u0A, then short-circuit the input positive and negative poles and press "OK "Button to complete displaying J10u, apply a standard DC voltage of 10.00V between the input positive and negative electrodes, press the" OK "button, and then display J2.0A, apply to the output negative electrode (inflow direction) and input negative electrode (outflow direction) After a constant DC current of 2.0A, press the "OK" button once to complete the calibration. The tester will pre-check the calibration data. If the calibration data is reliable, it will display 4 calibration numbers in turn and then exit. If the pre-audit believes that the data is not reliable, discard the data and exit.

1. 模块参数：
- 电源电压：DC4.5-6V （micro USB接口）
- 工作电流：不超过70mA
- 放电电压：1.00V-15.00V 分辨力0.01V
- 终止电压范围：0.5-11.0V

- 电池容量范围：9999Ah（1Ah=1000mAh）2.
2. 数值较大时通过小数点移位切换，当低于10Ah时显示为X.XXX ，达到10Ah以上显示为XX.XX，以此类推。
3. 电路板尺寸：50mmX37mm
4. 成品尺寸：50mmX37mmX17mm （长X宽X高 ，包含铜脚高度）
5. 板及配件重量：单板28g（包括铜柱），两只5W陶瓷电阻9g，50W电阻约27g（含线）
6. 注意：本电路为了提高电压测量精度，特别设计了直流偏置，当端子什么都不接时会显示一个很小的电压，并不影响实际测量，如果您短接输入端子（这时候必然0V）就会显示0。想弄懂原理的可以去查阅电工学里的叠加定理。
7. 使用方法：
- 被测电池应当首先充满电。
- 连接被测电池正极到输入正，负极到输入负极，不可接反（带负载接反可能会损坏电路）！连接负载至输出正极和输出负极，给测试仪micro USB通工作电源（不可用台式机或者笔记本USB供电），此时显示电池电压。
- 直接启动测试只需要按动一下“OK”按键，测试仪能够根据电池满充电压自动制定合适的终止电压，并会闪烁显示3次后启动测试。需要人工制定终止电压只需要在电池电压显示状态下按动“+”或“-”按键修改，终止电压显示为P开头，后面代表电压值，分辨率0.1V，设定好后按动“OK”开始测试。
- 测试开始后测试仪会接通控制负载的电子开关，测试过程数据显示会在放出容量（Ah），当前放电电流（A）以及电池电压（V）之间轮显。当电池电压到达设定终止电压后，测试仪切断负载控制开关，显示数据停留在容量（Ah）上面并且和对应指示灯一起快速闪烁，此时显示的容量就是电池的实际放电容量，按动一下“OK”可以终止闪烁让数据稳定显示，再次按动“OK”按键恢复到刚上电状态可以更换电池测试下一节……
8. 错误代码及含义：
- Err1：电池电压高于15V
- Err2：电池电压低于设定终止电压
- Err3：电池无法承受负载放电电流或者线路内阻太大
- Err4：电流过大（电流超过3.1A）
- Err5：使用不当或者接线错误已经导致设备烧毁无法使用（电流取样或者控制开关MOS烧毁）
9. 注意：如果电池接反，在负载接通且负载电流较大（约>0.8A时），将可能损坏电路开关管！！
10. 二次校准操作：同时按住三个按键给测试仪通电，进入校准模式，首先显示校准记录次数之后进入正式校准采样程序显示0u0A，此时短接输入正负极后按动一下“OK”按键，完成显J10u，给输入正负极之间施加10.00V标准直流电压后按动一下“OK”按键，之后显示J2.0A，给输出负极（流入方向）和输入负极（流出方向）施加2.0A恒定直流电流后按动一下“OK”按键完成校准。测试仪会对校准数据进行预审核，如果校准数据靠谱，则会依次显示4个校准数后退出，如果预审核认为数据不靠谱，则丢弃数据退出。
