6. OPERATION INSTRUCTION
MEASURING VOLTAGE
1. Connect the black test lead to the "COM" jack and the red to the "INPUT"
jack.
V~
V—
2. Set the function switch to
or
range.
Select auto range or manual range with the "RANGE" button.
3. In manual range, if the voltage magnitude to be measured is unknown
beforehand, select the highest range.
4. Connect the test leads across the source or load to be measured.
5. Read LCD display. The polarity of the red lead connection will be
indicated when making a DC measurement.
Note:
a. In small range, the Digital multimeter may display an unstable reading
when the test leads have not been connected to the load to be measured.
It is normal and will not affect the measurements.
b. In manual range mode, when the Digital multimeter shows the over
range symbol "OL", a higher range must to be selected.
c. To avoid damage to the Digital multimeter, don't measure a voltage
which exceeds 400 V DC (for DC voltage measurement) or 400 V AC (for
AC voltage measurement).
MEASURING CURRENT
1. Connect the black test lead to the "COM" jack. If the current to be
measured is less than 400 mA, connect the red test lead to the "INPUT"
jack. If the current is between 400 mA and 10 A, connect the red test lead
to the "10 A" jack instead.
2. Set the range switch to desired µA , mA or A range.
If the current magnitude to be measured is not known beforehand, set the
ranges switch to the highest range position and then reduce it range by
range until satisfactory resolution is obtained.
3. Select DC current measurement or AC current measurement with the
"Select" Button.
4. Select auto range or manual range with the "Range" button. In manual
range, if the current magnitude to be measured is not known beforehand,
select the highest range.
