1. Set the function switch to the mV -position.
2. Press the push-button labeled MODE to select mV (DC) or
mV~ (AC).
3. Insert the black test lead into the negative COM - jack. Insert the
red test lead into the positive V//CAP/Hz%/Temp - jack.
4. Read the mV voltage in the display. When the values are
negative, a “-” symbol is displayed.
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.
Low Pass Filter:
To avoid false AC voltage measurements with pulse width
modulated signals or disturbances of the mains frequency, you can
turn on the low pass filter when making an AC voltage
measurement.
