Ac Voltage Measurements - Harbor Freight Tools 7 function Owner's Manual

Controls
1. Disconnect Test Leads. Use a screwdriver to
remove both screws on the rear of the unit.
Observe polarity, and attach a 9V battery to
the posts. Replace and secure the cover.

AC Voltage Measurements

Measure AC conductors carrying up to 250 VAC, 45-450 Hz.
1. Turn the Range Selector Switch to 250
ACV setting. Always start with the highest
range if the voltage is unknown.
2. Plug the red lead into the VΩmA (Center)
Jack. Plug the black lead into the COM
(Bottom) Jack. Switch the Multimeter ON.
3. Carefully touch the exposed conductors
with the tips of the probes to measure
the voltage (not amperes).

2. Do not apply voltage to the Test Leads when
they are connected to the COM (Bottom) and
VΩmA (Center) Jacks and the Multimeter
is in an Ohms testing setting. Damage can
occur to the multimeter or the fuse may blow.
3. Do not switch between testing modes with
the multimeter connected to a circuit.
4. Read measurement.
5. If the voltage is less than 200 volts, set the
Range Selector Switch to the lower range.
6. When testing is complete, remove Test
Leads and store with multimeter.
