Connect the red test lead to the “V.W.mA” jack and the
black lead to the “COM” jack.
Set rotary switch at desired DCV position. If the voltage to
be measured is not known beforehand, set range switch
at the highest range position and then reduce it until
satisfactory resolution is obtained.
Connect test leads across the source or load being
measured.
Read voltage value on the LCD display along with the
polarity of the red lead connection.

Connect the red test lead to the “V.W.mA” jack and the
black test lead to “COM” jack. (For measurements
between 200mA and 10A, remove red lead to“10A” jack.)
Set the rotary switch at desired DCA position.
Open the circuit in which the current is to be measured,
and connect test leads in series with the circuit.
Read current value on LCD display along with the polarity
of red lead connection.
