automatically switch o after 15 minutes if no operation
has occurred. There will be 5 beeps before it shuts down.
• Buzzer – will sound when switching on or any button is
pressed, or a function is selected. It will also sound if the
reading is over the specied range of the Multimeter.
7.3 AC/ DC Voltage and Resistance Test
Measurements
1. Use the AUTO mode or press the SELECT button (12) to
select the required measurement type.
2. Connect the negative test lead (14) to the common earth
probe terminal (9) and connect the Positive test lead (16)
to the voltage, resistance, circuit on/o, frequency,
temperature terminal (8).
3. Position the test lead contacts across the source of the
circuit to be measured, observing the correct polarity.
4. Enable the power to the circuit to be measured. The
voltage value is displayed on the LCD screen (4) along
with the voltage polarity if reversed.
Resistance
− If the resistance to be tested is part of a circuit,
switch the circuit o, disconnect the power and
allow all capacitors to discharge before
measurement.
WARNING! NEVER measure resistance
