Turn the multimeter dial so its white or yellow indicator mark is pointing to the meter's "OFF" position.
Install the leads. If measuring for voltage, resistance or amperage below 10 amps, connect the elbow-shaped ends of the red and black lead, as follows, pressing them into the sockets until snapped firmly into the sockets: red lead in the socket labeled "V ma"; black lead in the socket labeled "COMM" (stands for COMMON or GROUND). If measuring amperage of 10 amps or higher, keep the black lead plugged into "COMM" but snap the plug of the red lead into the socket labeled "10A."
Check to ensure the leads are plugged into the multimeter completely by turning the multimeter selector from the "OFF" position to the "OHMS" position and touch the pointed metal tips of the red and black leads together. If the digital display shows a reading of "0.000" when touching the leads together, the installation of the leads is successful. If the display shows a reading of "1 -" when touching the tips together, follow all three steps once more, as this means the leads aren't snapped into the sockets completely.
Things You Will Need
- Red multimeter lead
- Black multimeter lead
- The narrow, sharp ends of the leads are called the "probes" and the wider ends are the connection plugs. Never poke the sharp probe ends into the multimeter's connection sockets as this may bend the socket receptacle springs. Always press only the wide plug ends into the sockets.
