[Nut-upsuser] CP1000PFCLCD really high output voltage

[jalano]

Cyberpower provides a binary-only Linux utility called "powerpanel" - I installed the powerpanel_123_amd64.deb package on my ubuntu system, and this is what it says:

When I run: pwrstat -status

The UPS information shows as following:

	Properties:
		Model Name................... CP1000PFCLCD
		Firmware Number.............. CRDA103*AF1
		Rating Voltage............... 120 V
		Rating Power................. 600 Watt

	Current UPS status:
		State........................ Normal
		Power Supply by.............. Utility Power
		Utility Voltage.............. 118 V
		Output Voltage............... 118 V
		Battery Capacity............. 92 %
		Remaining Runtime............ 37 min.
		Load......................... 72 Watt(12 %)
		Line Interaction............. None
		Test Result.................. Passed at 2013/04/05 20:49:34
		Last Power Event............. None

I also loaded the Windows utility in a VM, and it unfortunately had even less useful information.  The battery capacity is lower because I decided to initiate a self-test just to see if would actually change.
