Ac Voltage Measurements - Craftsman 82005 Owner's Manual

AC VOLTAGE (FREQUENCY, DUTY CYCLE)
MEASUREMENTS
WARNING: Risk of Electrocution. 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. Make sure
the probe tips are touching the metal contacts inside the
outlet before assuming that no voltage is present.
CAUTION: Do not measure AC voltages if a motor on the
circuit is being switched ON or OFF. Large voltage surges
may occur that can damage the meter.
1. Set the function switch to the V
2. Insert the black test lead banana plug into

Insert red test lead banana plug into the
positive V jack.
3. 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.
4. Read the voltage in the display.
5. Press the HZ/% button to indicate "Hz".
6. Read the frequency in the display.
7. Press the Hz/% button again to indicate
"%".
8. Read the % of duty cycle in the display.
