主要电气参数（摘录自说明书）

Key specs (from manual)

注：表格行为在「亏电停止 / 满电停止」阈值之间才会导通容量测量；批量测试需先在参数页设定内阻上限与电压下限。完整操作以 PDF 为准。

Capacity paths require voltage between discharge/charge stop thresholds; batch mode needs IR and V limits configured first. Follow the PDF for full procedures.

机身与细节

Unit and details

夹具选型

Fixture options

主机标配开尔文夹，可按被测电池形态加配探针或电池座；三种夹具可任意组合选购。

The unit ships with Kelvin clips; add probes or a battery holder to match your cell format. The three fixtures can be combined freely.

操作要点

How it works

测量内阻与电压

Measure IR and voltage

1. 选中页面 1（内阻检测）
2. 用四线开尔文夹或其他配套夹具接触电池正负极
3. 屏幕同时读出电池电压与内阻值；左下角图标显示当前使用的内阻挡位

1. Select page 1 (IR measurement)
2. Contact the cell terminals with the 4-wire Kelvin clips or another fixture
3. The screen shows voltage and IR together; the lower-left icon indicates the active IR range

批量筛选电池

Batch screening

1. 选中页面 4（批量检测），勾选筛选内容（内阻或电压）
2. 设定「内阻阈值」：结果低于该值为合格电池
3. 设定「电压阈值」：结果高于该值为合格电池
4. 完成设置后依次接触不同电池，即可快速筛选

1. Select page 4 (batch mode) and choose the criteria (IR and/or voltage)
2. Set the IR limit: readings below it pass
3. Set the voltage limit: readings above it pass
4. Touch each cell in turn to screen them quickly

容量测量（充电法 / 放电法）

Capacity test (charge or discharge)

1. 选中页面 2（电池容量），先用「数据清零」清除历史数据
2. 设置满电阈值与亏电阈值，电池电压须落在两者之间，内部开关才会导通
3. 充电法：先放空电池，接上充电电源；放电法：先充满电池，接上负载
4. 仪器检测到充放电电流后自动记录容量，数值停止上升即为最终容量
5. 可选：用万用表比对电压，在「补偿校准设置」中调整导线补偿阻值消除线阻偏差
6. 注意：容量测试务必区分电池正负极，不能接反

1. Select page 2 (capacity) and clear history with "data reset"
2. Set the full and empty thresholds; the internal switch only closes when voltage sits between them
3. Charge method: drain the cell first, then connect a charger. Discharge method: fully charge, then connect a load
4. Once charge or discharge current is detected, capacity logs automatically; the final value is where it stops rising
5. Optional: compare with a multimeter and trim the lead compensation to remove wiring error
6. Note: observe polarity during capacity tests — never reverse the leads

放电负载选型（说明书推荐表）

Discharge load selection (from manual)

放电法测容量需外接大功率可调电阻，一般按 1C 电流放电；功率越大越好。

Discharge testing needs an external high-power adjustable resistor, typically at 1C; higher wattage is better.

数据解读

Reading the data

测量电池内阻可以评估电池性能与健康状态、预测寿命衰退、诊断故障或损坏，并优化使用效率。

Internal resistance reveals cell health, predicts ageing, helps diagnose faults and improves how cells are used.

内阻

Internal resistance

• 内阻低：电流输出能力强、电压稳定，性能较好
• 内阻高：电流输出受限、电压可能不稳，性能较差
• 内阻随时间增加而上升，会导致性能下降与寿命缩短

• Low IR: stronger current delivery and steadier voltage — better condition
• High IR: limited current and unstable voltage — degraded condition
• IR rises over time, reducing performance and service life

容量

Capacity

• 容量越大，存储电荷越多，使用时间相应增加
• 高容量电池更能满足大电流需求，低容量电池在大电流下更快耗尽
• 容量大的电池通常体积和重量也更大

• Higher capacity stores more charge and runs longer
• High-capacity cells handle heavy current better; small ones drain faster
• Larger capacity usually means a bigger, heavier cell

使用注意与保养

Notes and care

• 开尔文夹短接不为 0？两夹直接互夹不算真正短路，应夹在一根很粗的导线上并相互靠近；此时 0.2mΩ 以内属正常，如需更接近 0 可在设置中启用 Amend 与 offset_on
• 参数设置：先按「切换参数」选中修改项，再按「确认键」进入；退出同样要用「切换参数」选中「退出」项
• 修改数值：用「确认键」选中修改位（变红），再用上下键改数值
• 操作时避免接触裸露的电线和连接器，注意电池正负极连接正确
• 定期清洁仪器外壳，避免液体或异物进入内部；本产品提供一年保修

• Kelvin clips not reading zero? Clipping them together is not a true short — clamp both onto one thick wire close together. Within 0.2mΩ is normal; enable Amend and offset_on for near-zero work
• Settings: press "switch parameter" to select an item, then "confirm" to enter; exit the same way via the "exit" item
• Editing values: "confirm" selects the digit (turns red), then use up/down to change it
• Avoid touching bare wires and connectors; always check battery polarity
• Clean the housing regularly and keep liquids out; one-year warranty included
