OPERATION - DC VOLTAGE MEASUREMENT

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