This knob is used for adjusting the zero point of the meter. It's often referred to as the "infinity" knob because it's used to calibrate the meter to read infinite resistance (open circuit).

This switch or knob allows you to select the measurement function (voltage, current, resistance) and the range (e.g., 10V, 100V, 1000V, etc.). It determines the maximum value the meter can measure for a given function

This refers to the specific measurement range selected using the range selector.

One of the test probes connected to the meter. It's typically red and is used to make contact with the positive side of a circuit or component.

The two wires with probes at their ends. They are used to connect the meter to the circuit being tested

The indicator that moves across the scale to show the measurement value. It's connected to the meter movement

: The other test probe, usually black, connected to the meter. It makes contact with the negative side of a circuit or component

The terminals or sockets on the meter where the test probes are plugged in. They are usually labeled with the appropriate symbols for positive and negative

: This knob is used to fine-tune the meter's zero point for resistance measurements. It ensures accurate readings when measuring low resistances.
