DIGITAL MULTIMETER
OPERATING INSTRUCTION
4.10 MEASURING AC VOLTAGE
WARNING
You can’t input the voltage which more than 600V rms
AC, it’s possible to show higher voltage, but it’s may
destroy the inner circuit.
Pay attention not to get an electric shock when
measuring voltage.
4.10.1 Connect the black test lead to the COM jack and the
red test lead to the INPUT jack.
4.10.2 Set the transform switch
at the V range position.
4.10.3 Put down the ‘FUNC.’ to
enter the AC measurement.
Auto range or manual
range can be transformed
by putting the ‘RANGE’.
4.10.4 Connect test leads
across the source or load
under measurement.
4.10.5 You can get reading from
LCD.
NOTE:
• At the little voltage range, the meter will show unsteady
reading when test leads haven’t reach the circuit, it’s
normal because the meter is very sensitivity. When test
leads touch the circuit, you can get the true reading.
• At the manual range mode, when only the figure ‘OL’ is
displayed, it indicates overrange situation and the higher
range has to be selected.
