True RMS Digital Multimeter
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.
