Connect the red test lead to the “V.Ω.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.
