Hi Ron,

Thanks for the somewhat longer reply than mine. ;-)

I have some devices with 9631 cards (which are 9630 with UIO sockets as far as I know). We don't use upsAdvOutputLoad on those, but upsHighPrecOutputLoad. (At least on my 1- and 3-phase devices) - can you check the value returned? And perhaps which OID we are using on your install (quickly via the graph -> rrd command -> check the filename used, or alternatively via the 'sensors' table in the database).
