what do the numbers mean?

I recently purchased(4months ago) the APC BR1000G. When I first power up, the display shows the line voltage first, then after a few seconds it shows numbers such as 246 then jumps to 346, holds for a couple of seconds and then goes back to indicating line voltage. I presume this occurs when the UPS is under a test load. My question is, what range of readouts during this load process should I expect? There are also several "clicks" or noise of something clicking after the line voltage comes back on the display. My user's manual doesn't give me a sequence of events when you first power up the UPS to know what processes are happening during this startup. Any information on this would be appreciated. Thanks.

Good day Gilloz,

When you turn the UPS on, the load or the equipment plugged into the battery backed up outlets are still turned off right? You see the 4.5 hrs or 287 mins for the runtime since the load isn't powered by the unit. Once you turn on the load you should see a change in the runtime, it should be shorter depending on what the power consumption is of the equipment plugged into the battery backed up outlets. As your load(power consumption) increases, the runtime decreases. One more thing, the runtime also depends on how much the battery charge is.

Thank you Kulot for your response. OK, I get it now. Yes you're right. When I switch ON my UPS, nothing is ON or no load is present. But then again, when would there ever be a situation that everything came ON at the same time that I switch ON the UPS? That wouldn't make any sense. Basically what you are saying is the number that comes up indicates or reflects a direct correlation to the amount of charge on the battery. I would actually like to see a number closer to how much time I have with a loaded condition. You would think that after several turn-ons, the unit would store the average load and precalculate a number closer to the load be used by my system setup to give me the amount of minutes that my UPS would sustain during a power outage. I guess that is too much to ask for. Anyway Kulot, thanks again for your response. Have a good week.
