4.17.1 Plug the black test lead into the COM jack.
When
the current to be measured is under 400mA, plug the
red test lead into the mA jack; when the current to be
measured is over 400mA but under 10A, plug the red
test lead into the 10A jack.
4.17.2 Set the rotary selector to the
A range position.
4.17.3 Press the "SELECT" button to switch to DC
measurement. Then press the “RANGE” button to
choose the auto range or manual range mode.
4.17.4 Connect the test leads to the circuit for measurement.
4.17.5 Take the reading on the main indicator of the LCD.
The polarity symbol denotes the polarity of the end
connected by the red test lead.

NOTE:
1) At the manual range mode, when only ‘OL’ or ‘-OL’ is
shown on the LCD, it means the measurement has
exceeded the range.
A higher range should be
selected.
2) At the manual range mode, when the scale of the value
to be measured is unknown beforehand, set the range
to the highest.
3) “
” means the maximum current of the mA jack is
400mA and the maximum current of the 10A jack is
10A.
At the 10A jack, current exceeding the limit will
blow the fuse.
