This value is reported by the UPS in 'UPS.PowerSummary.Voltage' and we
display it 'as is'. It could be that the measuring circuit in your UPS
is
broken, or that all similar models require a correction factor / offset.
There is really nothing we can do about the device reporting 'wrong
values' at this time.
