Ac Voltage Measurements - Craftsman 82003 Owner's Manual

AC VOLTAGE (Frequency, Duty Cycle) MEASUREMENTS
AC VOLTAGE: The probe tips may not be long enough to
contact the live parts inside some 240V outlets for appliances
because the contacts are recessed deep in the outlets. As a
result, the reading may show 0 volts when the outlet actually
has voltage on it.
I ARNING: To avoid electric shock, make sure the probe tips I
are touching the metal contacts inside the outlet before
I
assuming no voltage is present
I CAUTION: Do not measure AC voltages if a motor on the I
circuit is being switched ON or OFF. Large voltage surges may
I
occur that can damage the meter.
1. Set the function switch to the V position.
2. Press the MODE button to select AC (if
necessary)
3. Insert the black test lead banana plug into
the negative COM jack.
Insert red test lead banana plug into the
positive V jack.
4. Touch the black test probe tip to the neutral
side of the circuit.
Touch the red test probe tip to the "hot" side
of the circuit.
5. Read the voltage in the display.
6. Press the HZ/% button to indicate "Hz".
7. Read the frequency in the display.
8. Press the Hz/% button again to indicate "%".
9. Read the % of duty cycle in the display.
