Measure a genuine 120VAC (or 230VAC) source and check the meter shows the correct reading for a live and dangerous condition. Turn off the supply to the circuit you are working on and check for 0V. Before touching anything, go and check a live circuit elsewhere to be sure your meter didn't coincidentally die between the previous steps.
