5.3. AC Voltage measurements
Warning:
Risk of Electrocution. The probe tips may not be long enough to
contact the live parts inside some 230 V 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 contacting 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 during the ON
or OFF operations that can damage the meter.
