Default Testing a (second-hand) transformer for newbs


I can get a secondhand Amplimo transformer 2x22V/500VA for my Aleph30. (Planning to use a CRC on it). I'm going to look at it tomorrow afternoon. Is there an easy way to check it's functioning with a simple DMM? I'm thinking I could put a 2k2 resistor across each secondary and hook up the primary to the mains, then measure VAC across the resistor, but would that tell me enough?
Are there other things I could look at?

I guess the easiest and most obvious thing would be to check that none of the windings are open circuit.
