Paper clips... very carefully.
If the probes/leads on your meter are too big, get a bit of metal that will fit inside the holes on the connector. They will be nothing more than "pins" sticking out for you. Perhaps wrap electrical tape around them so you don't short anything. Do this before plugging it in to make sure you will not accidentally short any leads.

Then touch the VOM's probes to the "pins" you made.
