OPERATING INSTRUCTIONS DC VOLTAGE MEASURE-

MENT

1. Connect the red test lead to the "V.Ω.mA" jack and the black

lead to the "COM" jack.

2. 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.

3. Connect test leads across the source or load being measured.

4. Read voltage value on the LCD display along with the polarity of

the red lead connection.
