[Test-Equipment] Isolation transformer

[Rasputin Novgorod]

I have a small 115vac Isolation transformer that I power
projects with, expecially transformerless ones,
for safety's sake. This is an older transformer that has
been repaired. How do I test it, with an ohm meter,
to know that it is wired correctly and safely? The input
has a three pin plug, the output is a standard three-pin
outlet. I presume:

1) continuity between input and output grounds?
2) no continuity between either output lead to output ground?

I ask because I had an argument with an inspector about
my 15 amp/220vac Sola auto/isolation transformer for the 
whole shop. He wanted all grounds and one side bonded
thru, which seemed to me to short circuit the isolation...

Please don't guess, but if you really know how these things
should be wired, I'd be grateful for direction...

Sincerely
