Of course.   The UPS is in production (ie., powering the servers in my
house), so it may be a few days before I can ~play~.  Let me know what I
need to do.

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."

It's looking as if the output.voltage value is not correct.  ;)

Results from upsrw:

Remaining battery level when UPS switches to LB (percent)
Maximum length: 10
Value: 10

Remaining battery runtime when UPS switches to LB (seconds)
Maximum length: 10
Value: 300

Interval to wait after shutdown with delay command (seconds)
Maximum length: 10
Value: 20

Interval to wait before (re)starting the load (seconds)
Maximum length: 10
Value: 30
