AC VOLTAGE MEASUREMENT
1) Set the function/range switch to the ACV range.
2) Touch the test leads to the circuit under test. With AC volt-
age, the polarity of the test leads is not a factor. Read the
voltage level of the circuit on the display.

Common AC Voltage Measurements
Wall Receptacles
If the receptacle is controlled by a switch, make sure the
switch is ON. Set the function/range switch to the ACV setting.
Touch the test leads to the "hot" and "neutral" slots of the
receptacle (see fig. 5). The display should read 110 VAC. To
test for proper grounding of the receptacle, touch one test lead
to the 'hot" (narrow) side of the receptacle, and the other test
lead to the ground slot. The tester should read 110 VAC as
before. To test for proper grounding of non-polarized recepta-
cles (fig.6), alternately touch the test leads between the recep-
tacle slots and the wall plate screw. The tester should indicate
110 VAC when one test lead contacts the "hot" side of the
receptacle. If ground contact cannot be made on the wall plate
screw, remove the wall plate and touch the electrical box with
the test lead in the same manner as before. The tester should
read 110 VAC with one test lead touching the electrical box
and the other touching the live side of the receptacle. If not,
the receptacle is not properly grounded.
Appliance Receptacles
Set the function/range switch to the ACV setting. Touch the
test leads to the receptacle slots. The tester should read 220
– 7 –
VAC between the two "hot" sides of the receptacle, and 110
VAC between the neutral slot and either of the two "hot" sides
(see fig. 7).
Figure 7
Circuit Breaker Panel
To test for defective circuit breakers, set the function/range
switch to the ACV setting. Touch one test lead to the neutral
(buss) terminal strip of the breaker panel and the other test
lead to the terminal on the circuit breaker (see fig. 8). The
tester should read 110 VAC.

RESISTANCE/CONTINUITY MEASUREMENT
For resistance and circuit continuity testing with power OFF
1) Set the function/range switch to the ohms setting.
2) Touch the test leads to the resistance or non-energized
circuit to be measured. Measure the value of the reading
on the display.
