Connect the red test lead to the “ V.Q.mA “ jack· and the black lead to the “COM” jack.
Connect the red test lead to the “V.Q.mA” jack and the black test lead to “ COM” jaCk.
(For measurements between 200mA and lOA, remove red lead to “1 OA “ jack.)
Connectthe red test lead to “ V.Q.mA “ jack and the black test lead to the “ COM “
jack.
Set the rotary switch at the desired DCA position.
Set the rotary switch at desired ACV position .
Open the circuit in which the current is to be measured. And connect test leads in
series with the circuit
Connect test leads across the source or load being measured.
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.
Read current value on LCD display along with the polarity of red lead connection.
