4.3. AC Voltage 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.
• Set the function switch to the VAC position.
• Insert the black test lead banana plug into the negative
COM jack. Insert red test lead banana plug into the
positive V jack.
• Read the voltage in the main display.

4.4. Frequency Measurements

• Set the function switch to the Hz% position.
• Insert the black test lead banana plug into the negative
COM jack. Insert the red test lead banana plug into the
positive V jack.
• Read the Frequency in the display.
• Press the MODE key to switch the Duty functions.
• Read the Duty in the display.

4.5. Resistance Measurements

To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any resistance measurements. Remove the batteries and unplug
the line cords.
• Set the function switch to the Ω CAP
• Insert the black test lead banana plug into the negative COM jack. Insert the red test
lead banana plug into the positive Ω Jack.
• Read the resistance in the display
