To check:

• Check the multimeters to make sure there aren't blown 500 mA fuses.
• Make sure compasses are aligned with north. (If reversed or if not responsive to Earth's field, jiggle a neodymium magnet aggressively back and forth along the face of the compass until needle returns to correct orientation.)
