At the very basic level you have the device itself, along with two probes, which are the black and red cables that have plugs on one end and metal tips on the other. Analog multimeters use a microammeter with a moving pointer to display readings. This pdf also shows the analog multimeter diagram. Step 3: Connect the probes in the circuit according to the polarity. <> Multimeters are a tool that we use to measure multiple characteristics of electronics.
