A multimeter is an electronic measuring instrument that combines several measurement functions in one unit.

Test leads are used to connect to whatever device you're planning on testing and measuring.

Zero adjustment knob is a small knob usually located near the dial that is labeled "Ohms Adjust," "0 Adj," or something similar.

The selector switch allows you to change the function between volts, ohms, and amps, and to change the scale of the meter.

In a multimeter, the needle of pointer must be located at the left position if the test leads are not in contact with anything.

Voltage is measured in order to determine whether or not the circuit is Alternating Current or Direct Current?

In a multimeter, the needle of pointer must be located in the right position if the test leads are in contact with anything.

The dial of the multimeter has the arc-shaped scales visible through the window and a pointer which will indicate the values read from the scale.

The selector switch or knob allows you to change the function between volts, ohms, and amps, and to change the scale (x1, x10, etc.) of the meter.

Most multimeters have several jacks used for where you'll insert the test leads.

There should be two test leads or probes which are used to connect to whatever device you're planning on testing and measuring.

The Zero Adjustment knob is a small knob usually located near the dial that is labeled "Ohms Adjust," "0 Adj," or something similar.

When multimeter measures resistance in ohms, it cannot measure continuity because resistance and continuity are opposites.

If the test leads are not in contact with anything, the needle or pointer of an analog meter will rest at the left-most position.

Connect the black test lead to the jack marked "Common" or "-".

Hold the probes at the end of the test leads together. The meter pointer should move fully to the right.

A device that has burned out will not show "open" on the meter when testing if your fingers provide an alternate path around the device, like when they are touching the probes.

Many times, the voltage to be measured has a value that is unknown.

The range chosen by the selector knob determines which voltage scale to read.

In measuring amperes, make sure you've measured the voltage first.

If the circuit to be tested is AC but the meter will only measure DC amps (or vice versa), stop.

The meter must be able to measure the same mode (AC or DC) amps as the voltage in the circuit, otherwise it will indicate 0.
