6.2. AC Voltage Measurement

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 highest VAC Position.

2. Insert the black test lead banana plug into the negative COM Input Jack;

Insert the red test lead banana plug into the Positive Input Jack.

3. Touch the black test probe tip to the negative side of the circuit; Touch

the red test probe tip to the positive side of the circuit.

4. Read the voltage in the display.

5. Reset the function switch to successively lower VAC Position to obtain a

higher resolution reading, the display will indicate the proper decimal

point and value.
