Connect the red (positive) probe to the Voltage and Resistance Socket.

Connect the black (negative) probe to the Common/Ground Socket.

Set the multimeter knob for continuity testing. This is typically labeled with diode/audio symbols.

As shown in the photo, the multimeter will read "OL" if the steps above have been followed properly.

To ensure the functionality of the multimeter, touch the two probes together and an audible beeping sound should be emitted.
