DIGITAL MULTIMETER
OPERATING INSTRUCTION
4.9.1 Connect the black test lead to the COM jack and the
red test lead to the INPUT jack.
4.9.2 Set the transform switch
at the V range position.
4.9.3 Put down the ‘FUNC.’ to
enter the DC
measurement. Auto
range or manual range
can be transformed by
putting the ‘RANGE’.
4.9.4 Connect test leads
across the source or load
under measurement.
4.9.5 You can get a reading
from LCD display. The
polarity of the red test lead connection will be indicated.
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.
• At the manual range mode, when the value scale to be
measured is unknown beforehand, set the range selector
at the highest position.
