I like being able to find the charge level of hte battery, how much power the system is drawing, and things of that nature. If the UPS also does AVR, it can be handy to know how often it has to supplement or reduce line voltage. And while the calibration is not as good as I would like, they can also be used to record line voltage that can provide clues to other voltage related problems you may experience. (It can save you from having to attach a recording volt meter.) Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
