A smart wearable device is a hardware terminal that combines multimedia, sensing, identification, wireless communication, cloud services and other technologies with daily wear to realize user interaction, life entertainment, health monitoring and other functions. There are smart watches, smart bracelets, smart glasses, smart clothing and so on in our common life. Whether we use smart wearable devices to track steps or record sleep time, we all hope that the devices we use are accurate and reliable. Therefore, in order to ensure the reliability and accuracy of the device, smart wearable devices must be completed strict and comprehensive test before delivery.

The fuel cell voltage monitor (CVM) is an important part of fuel cell engine system and stack inspection. It has the characteristics of multiple channels, fast response and high voltage measurement accuracy. It can perform real-time analysis of the monitored voltage data group, comprehensive and rapid fault diagnosis, and real-time monitoring, diagnosis, storage and query of the status and performance of the fuel cell stack monolithic, which can ensure the stability and reliability of the fuel cell, and improve the working efficiency of the fuel cell.
