The front display of the device is a digital or quartz-crystal display that shows alphanumeric characters (1, 2, 3, and ABC), as well as up to four digits. It also displays a negative symbol.

Model SAnd Prices

Multimeters in the shape of pens (which look more futuristic than pens), can be held with one hand. They have a single probe that detects AC voltage without contact. These multimeters are among theest, with prices ranging from $27 to $40. They only have a few functions.

Handheld: This is the most common multimeter. It has a rectangular boxy shape, and it's easy to use. There are three ports and a selection dial. Handheld multimeters are available for between $10 and $40. High quality models range from $66 to $190.

Bench or box, these high-end multimeters can be used by engineers and electricians to test circuitry in a wider range. These multimeters have more ports, a wider selection of settings and a digital display (or LCD) that can show much more detail. They start at around $300 and can go up to $1,500.

Types Of Multimeters

Digital: These multimeters are the most popular type on the market. They have an easy to read digital display.

Analog: An older multimeter shows its readings by displaying a needle on a chart. They are difficult to read for laypeople, but they can be more convenient when dealing with sensitive measurements.

Single probe: Usually seen on AC voltage detectors that test current.

This single-purpose clamp meter is used by electricians for more safe AC current measurement. It clamps around the wire to measure current. For clamp meters to be safe, they must have a rating equal or higher than the wire that is being measured.

Selection Dial

The knob is usually located below the display. It has a variety of measurement settings.


Multimeters are equipped with at least two wires: one black and one red. Each wire is equipped with a connector at one end that fits into the ports of the multimeter.


The probe is attached to the other end of every multimeter wire. Multimeters can use a variety of probes. The most popular are alligator clips which are useful for testing circuits in a breadboard and test probes which are held at each end of the circuit. Multimeters often come with several types of probes that can be attached quickly to wires.

What To Look For In A Multimeter

Three key features are essential to a good multimeter.

Select voltage ranges
Ohm (resistance measurement)
Switching between AC and DC voltages

Before you buy a multimeter, determine what features it will have. Do you work with computers? It is essential to have a multimeter which can read DC current. A multimeter that can read AC current is necessary if you are working with AC wiring.

Tolerance range is also called the amount of current that you are likely to read. If you are testing a DC 12V power supply in a computer for example, your multimeter should be set to this range. A 12V circuit can be measured with a 20V setting, which will allow you to measure circuitry only up to 20 volts. The multimeter should be set at the tolerance of 120V AC wiring.

The majority of handheld multimeters come with AC and DC settings that are suitable for most DIY, auto repair, and computing needs. Check the settings carefully to ensure that your multimeter is set up for the project you are working on.

It is essential to have the ability to measure continuity and resistance in a circuit. If a wire has a broken connection and no current passes through it, then the ohm measurement on the multimeter indicates "infinite resistance". When a wire is in good condition, it will have a current flowing through it. This will result in a very low resistance reading when measuring using the ohm setting.

Some features are important, but others are not. These include:

Autoranging: This feature changes the range of the multimeter to match the circuitry that it is measuring. This feature is useful, but it may not be the best for less-experienced multimeter users.
Temperature probe: It is useful for measuring the temperatures of certain electronic components or the temperatures inside the computer case. This can be helpful when diagnosing certain circuitry issues. This is not necessary for the majority of multimeter applications.

Amperage measurement is not always necessary, especially when using computers.


The connection points are usually located on the front of the Multimeter where the probes are attached. One port is always marked "COM", which stands for "common," as it connects to the ground probe (or negative probe).

1. What’s The Best Way To Tell If A Multimeter Is Right For The Job I Need It For?

Check the maximum voltage and current ratings of the multimeter if you know what voltage ranges you will most likely measure. They should be higher than voltages you intend to measure, otherwise you may damage your multimeter or even receive an electric shock.

2. A Friend Told Me If I Don’t Set The Multimeter To The Right Setting After Each Use, I Can Break It When Testing A Circuit. What Does That Mean?

When you are ready to store your multimeter after using it, switch it into "friendly" mode. Connect the probes in "read voltage" mode (if they were previously configured to current mode) and set the dial for DC voltage. This is because users often grab their multimeters to measure voltage quickly. If you do this, it will prevent you from accidentally completing a circuit while in the wrong mode.

3. Do The Red And Black Wiring Colors On The Probe Wires Really Matter?

Black wiring is used to indicate the "ground" or "common wire" in electrical work. It doesn't really matter what color probe wiring you use when measuring current. However, following the guideline "black wire is ground and red wire is live" is good practice.
