Digole Regulators

Hi my Digole Regs have arrived at last.  How do I check that they are 3.3v and not faulty.  The jumper is open circuit but I could do with knowing which pin to check for 3.3v

if you have a multimeter, test across the two terminals labeled JMP, it should be open-circuit
Also make sure it has the 3.3v regulator chip on-board, and is not strapping the 5v supply to
the top left pin of the ARF
