The problem with correction factors is that we need to know how to apply them. Most of the other corrections are obvious scaling errors (e.g. multiplying by 100,000,000). Smaller corrections may be temperature-dependent.

Here's the line in drivers/cps-hid.c:

  { "output.voltage", 0, 0, "UPS.Output.Voltage", NULL, "%.1f", 0, NULL },

There is, of course, a non-zero chance of a bug somewhere in the driver, but most of the other HID subdrivers use "UPS.Output.Voltage" as well. Assuming NUT is parsing this value correctly, it should show up in the vendor software. Can you try loading the software in a VM?
