4.6 Preparation For Measurement
4.6.1 Set the transform switch to the right range. At the
manual range, when the value scale to be measured
is unknown beforehand, select the highest range.
4.6.2 When measuring, at first, connect to the public (COM)
testing line, then connect the probe tip of the meter to
the circuit under test.
4.6.3 If the battery voltage is less than 2.4V, display will show
“ ”, the battery should be changed at this time.

4.7 DC Voltage Measuring
WARNING
Risk of Electrocution.
You can't input the voltage which is higher than
600V DC, it's possible to show higher voltage,
but it may damage the inner circuit or cause
electrical shock.
Pay attention to avoid getting an electric shock
when measuring high voltage.
4.7.1 Rotate the probe socket clockwise to spin out the
probe from the meter.
4.7.2 Insert the black test lead or test clip in the
COM
jack.
4.7.3 Set the transform switch at the V range position.
4.7.4 Press the
“FUNC”
Button to transform to DC
measurement. Auto range and manual range can be
transformed by pressing the
“RANGE”
button.
4.7.5 Connect the probe tip of the meter and probe tip of the
test lead (or test clip) across the power source or be
loaded on the two sides under measurement.
4.7.6 You can get a reading from LCD display. The polarity
of the tested terminal which the tip of the meter
connection will be indicated.
- 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 meter
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, select the range to
the highest position and set down gradually.
NOTE:
