Yep, it's a good idea. Bend pin 8 up and make sure it doesn't have
contact with the socket, then connect it to pin 32 or 25. (Both VDD)

16, VSS is ground.
Maybe that volt meter also has an ohm meter function. That works
well as a continuity tester too - if two points are connected the
resistance will be 0.00 ohm.
