I'm pretty sure it reports whatever error codes it finds in a single pass.
Most of the faults are of the "check sensor" type that involve placing a
meter on the device to check it's function, so it's kind of a "have a look
and see if this thing's okay" type error detecting unit that helps pinpoint
the things to look at.

It probably does, but I've never got into it to that degree. Most of the
units I've ever tested were actually working to a degree, and had minor
faults. Having the A/C compressor out of action probably doesn't fit into
that category :)
The unit has a cabin air "sniffer" that lives in the dash just near the rear
window defrost switch, and that reports the cabin air temperature back to
the control unit. I'm sure it measures presure at some point in the A/C
system, but I'm not sure if it does so in order to satisfy cimate control
enquiries, or simply to failsafe the compressor in the event of a system
purge.
Basically I've found the system to be pretty dumb, and work on a "keep
trying" basis if it doesn't get any bad signals.

Good :)

No, you can simply buy them from your local lpg installer or parts supplier
without having to present a car for inspection.
Well, you can over here, anyway....
