Operation
Measuring Voltage
1)
Connect the black
test lead to the “COM” jack and the red to the “INPUT” jack.
2)
Set the function switch to V
or V
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 meter 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 meter shows the over range symbol “OL”,
a higher range must to be selected.
c.
To avoid damage to the meter, don
’t measure a voltage which exceeds
600Vdc (for DC voltage measurement) or 600Vac (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 200mA, connect the red test lead to
the “INPUT” jack. If the current is
between 200mA and 10A, connect the red test lead to the “10A” 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.
5)
Connect test leads in series with the circuit to be measured.
6)
Read the reading on the display. For DC current measurement, the polarity of the
red test lead connection will be indicated as well.
