3. Operating instructions
3.1 Measuring Voltage
1) Connect the black test lead (-) to the COM jack and the red test lead (+) to the
V/
Ω
/F jack.
2) Set the function switch at V
or V
∼
range to be used and connect test leads across
the source or load under measurement.
3) Read LCD display. The polarity of red connection will be indicated when making a
DC measurement.
3.2 Measuring Current
1) Connect the black test lead (-) to the COM jack and the red test lead (+) to the
mA/Cx jack for a maximum of 300mA. For a maximum of 10A, move the red lead to
the A jack.
2) Set the function switch at µA, mA or A range to be used and push
/
∼
button to
select DCA or ACA mode.
3) Connect test leads IN SERIES with the load in which the current is to be
measured.
4) Read LCD display. The polarity of red lead connection will be indicated when
making a DC measurement.
3.3 Measuring Resistance
1) Connect the black test lead (-) to the COM jack and the red test lead (+) to the
V/
Ω
/F jack.
2) Set the function switch at
Ω
range to be used and connect test leads across the
resistance under measurement.
