Common AC Voltage Measurements
Wall Receptacles
If the receptacle is controlled by a switch, make sure the
switch is ON. Set the rotary switch to 250 ACV. Touch the
red test lead to the “hot” and black to the “neutral” slots
of the receptacle (see fig. 3A). The needle indicator
should read 120V AC on the 0-250 scale. To test for
proper grounding of the receptacle, touch the red test
lead to the “hot” (narrow) side of the receptacle, and the
black test lead to the ground slot. The meter should read
120V AC as before.
