The LCD values look fine (usually 118 to 121 volts). I just measured
the output voltage at the UPS outlets (using an HP 974a DVM), it was
118.9 volts. The voltage from the wall outlet going into the UPS was
also 118.9 volts. While I was reading those values, the output.voltage
value was 142.
I didn't change any configuration from the factory default values,
though the UPS blurbs do mention "voltage boosting.&...

Notes:
1) the input to UPS was measured by a Kill-A-Watt device, the output
from UPS was measured by a HP 974a DVM. Prior to these tests, I ran
them from the same source, and they tracked pretty well, with the 974a
usually about 0.5 volts higher than the Kill-A-Watt. For the purpose of
this test, I figured that would be OK.
2) output.voltage and input.voltage were from the upsc command
3) the readings w...
