That is somewhat normal. Some cyber power systems return the #2, and some don't.

those numbers come directly from the ups itself. My cyberpower unit displays the correct voltage (I am in the US, we have 120V line power); however, there are probably different versions of the firmware that might not have the correct voltage readings (or your power fluctuates a lot)..
