测试精度的重要性
这张图表达了Arbin电池测试仪和另一个设备制造商之间的差异。使用不合适的测试设备可能会错过图上两个明显的跌落峰谷。一些厂家仍在销售十年二十年前设计的产品，而Arbin一直在努力改进我们的设计，以满足不断进步的行业需求。在为期 三年的ARPA-E项目 中，我们开发了大电流超高精度测试仪，并在后续的产品中广泛采用了这项研究中的新技术。这包括目前在售的 LBT系列, RBT-Cell，以及 HPS 设备系列。HPS超高精度测试设备代表了Arbin最顶尖的技术实力，可以称之为行业的技术天花板。而我们的LBT系列标准设备，也比市场上的其他测试仪更具备技术优势。
对于长期电池测试和长期电池预测来说，测量精度比单纯的控制精度更为关键。大多数其他的电池测试系统没有正确规定其精度和/或精度相对较差，这阻碍了从结果数据中得出的结论。重要的趋势和电化学指标可能仍然没有被注意到；如右图所示，在测量噪音中丢失。

CANBus/SMBus
Arbin提供 CANBus/SMBus接口， 允许使用CAN协议对Arbin测试器进行实时外部控制。该功能允许电池模块/电池组与BMS（电池管理系统）进行通信，或用于客户需要通过CAN进行外部控制的电池测试。
MTCI
The 温箱通讯接口（MTCI） allows the Arbin system to communicate with an approved third-party temperature/environment chamber. Arbin’s software can turn the chamber on/off and adjust the temperature during the test.
Battery Racks & Holders
各种夹具与电池支架可用于多种不同类型的电池，以搭建整洁规范的测试平台。
Arbin提供 热电偶 和 热敏电阻 sensor types to measure and record temperature during testing. They function independently so the user may flexibly assign them in any configuration with the main charge/discharge test channels. All data is automatically synchronized with the cell charge/discharge test data. Available sensor types include:
- K-型热电偶
- T型热电偶
- PT100热敏电阻（精度±0.5℃， PT100热敏电阻输入与Arbin MZTC多温区温箱兼容.)
- 10kΩ热敏电阻（NTC）
Arbin提供了一个可选的 自动校准模块 which can be used to re-calibrate the system when needed. All Arbin test equipment include a calibration interface as 使用外部仪表作为标准参考源 that can use an external meter to check or perform re-calibration. The AutoCal module is used to automate this process and will function without the need for an external meter.
注意：Arbin建议每年检查一次设备精度，并根据需要进行重新校准。
自动校准模块的标准额定电流可达200A，而扩展的 高精度分流器 也可用于600A电流的校准。
