双登UPS蓄电池不允许离线式容量测试！

第一、对于UPS系统的蓄电池组，不建议采用离线式测量法进行容量测试。

第二、进行在线式测量法和核对性容量试验时，对于本身具备蓄电池放电测试功能的UPS设备，开启双登蓄电池放电检测功能即可。对于没有该功能的UPS，需要在业主允许的情况下关断交流输入，进行在线放电试验。

First, it is not recommended to use off-line measurement for capacity testing of the UPS battery.

Second, when conducting on-line measurement and verification capacity test, for the UPS equipment with battery discharge test function, open the discharge test function of double-board battery.For UPS without this function, it is necessary to turn off ac input and conduct online discharge test with the permission of the owner.
