ac VoltaGe (FreQuencY, dutY cYcle) measurements
WARNING: Risk of Electrocution. Probe tips may not be long enough to contact the live parts
inside 240V outlets for appliances because the contacts are located deep in the outlets. As a result,
reading may show 0 volts when the outlet is actually powered. 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 and damage the meter.
