What is a Multimeter?

A multimeter is a device that measures multiple electrical properties, including voltage, current, and resistance.

It can also be used to measure capacitance, which is the ability of a material to store an electric charge.

There are two main types of multimeters: analog and digital.

Analog multimeters use a needle and scale to display readings. They are typically less expensive than digital multimeters and are easier to use for beginners.

Digital multimeters use a digital display to show readings. They are more accurate than analog multimeters and can measure a wider range of values.

Some digital multimeters also have features that analog models do not, such as the ability to store readings and connect to a computer.

Most multimeters can measure direct current (DC) and alternating current (AC). Some can also measure inductance and capacitance.

Multimeters are used in a variety of applications, including automotive diagnosis, electronics troubleshooting, and appliance repair.

To understand how a multimeter works, it is helpful to know a little bit about electricity.

What is a Multimeter?

Electricity is the flow of electrons through a conductor, such as a wire.

The rate of electron flow is called electric current.

Current is measured in amperes (amps). Voltage is the pressure that drives the current and is measured in volts. Resistance is the opposition to current flow and is measured in ohms.

A multimeter measures these electrical properties by using one or more sensors. For example, an analog multimeter has a movement that deflects when exposed to a magnetic field. This deflection is proportional to the strength of the magnetic field, which in turn is proportional to the voltage or current being measured.

Basic Understanding of the Farad Unit

The farad is the SI unit of capacitance, named after English physicist Michael Faraday.

A capacitor is a device that stores electrical energy in an electric field, and the farad is the unit of measurement for a capacitor’s storage capacity. One Farad is defined as the ability to store one Coulomb (unit of electric charge) of electrical energy in an electric field with a potential difference of one volt across its plates. [1], [2]

What are Microfarads?

Microfarads (μF) are a unit of measurement that quantifies the amount of electrical charge stored in a capacitor.

A capacitor is an electronic component consisting of two conductors separated by an insulator, which is used to store and discharge electrical energy. The microfarad also is the SI unit of capacitance and is equal to one millionth (0.000001) of a farad.

Microfarads aren’t the smallest unit of capacitance. Nanofarad (nF) and picofarads (pF) are smaller units. One nanofarad is equal to 0.000000001 of a farad, and one picofarad is equal to one trillionth (0.000000000001) of a farad.

The microfarad is a moderate unit of capacitance. Capacitors are available in a wide range of capacitances, from one picofarad (pF) to several farads. The microfarad is often seen in power supplies and audio equipment. [1], [2], [3]

Microfarads Symbol on Multimeter

There is nothing complex about the symbol for microfarads on a multimeter. Microfarads are more often than not, simply represented by a symbol “µF.” This symbol is used for microfarads when measuring capacitance with a multimeter. [1], [2]

How to Measure Capacitance

Now that we know what microfarads are, and what the symbol for them is on a multimeter, let’s go over how to measure capacitance. A capacitance is an electrical property that describes how much electric potential energy is stored in a material per unit charge. This is similar to how a battery stores chemical energy and releases it as electrical energy.

To measure capacitance with a multimeter, you will first need to drain the capacitor of any charge it has stored. To do this, you can simply short the leads of the capacitor with a piece of wire. Once the capacitor is discharged, you can remove the wire and set the multimeter to its “capacitance” or “microfarads” setting.

Next, find the positive and negative leads of the capacitor. The positive lead will usually be marked with a “+” sign, while the negative lead will usually be marked with a “-” sign. Connect the black lead of the multimeter to the negative lead of the capacitor, and the red lead of the multimeter to the positive lead of the capacitor.
If your capacitor doesn’t have markings, then it’s most likely non-polarized. In this case, you can connect the leads of the multimeter to any of the two terminals.

Finally, take a reading from the multimeter. The reading should be in microfarads (µF). If you get a reading in farads, you can simply divide the reading by 1,000,000 to get the equivalent capacitance in microfarads. For example, a reading of 1 farads would be the same as a reading of 0.000001 microfarads. If you don’t see a reading, then make sure that your multimeter is set to the correct setting and that your leads are properly connected.

Now that you know what the symbol for microfarads is on a multimeter, and how to measure capacitance, you should have no trouble using a capacitor in your next electronics project! [1], [2]

Safety Tips for Using a Multimeter

Since a multimeter can measure both AC and DC voltage, as well as current, it’s important to be aware of the potential risks involved in using one. Always use caution when working with electricity, and never attempt to measure a voltage or current that is outside of the safe range for your multimeter.

Always wear safety equipment

When working with electricity, it’s always important to wear the proper safety equipment. This includes gloves, goggles, and a face shield. You should also make sure that you are not wearing any loose clothing or jewelry that could come into contact with live electrical wires.

Stand on insulated surface

When measuring voltage, always make sure that you are standing on an insulated surface. This will protect you from shock in case of accidental contact with live electrical wires. Never touch the probes of the multimeter while it is turned on and connected to a circuit, as this could cause an electric shock.

Safety Tips for Using a Multimeter

Double check the settings

If you are measuring current, be aware that some multimeters can only measure AC current, while others can measure both AC and DC current. Make sure you are using the correct setting for the type of current you are trying to measure. Attempting to measure AC current with a DC-only multimeter, or vice versa, could damage the multimeter.

Use a well-calibrated multimeter

Make sure that your multimeter is properly calibrated before using it. Most multimeters will come with a calibration certificate that you can use to verify the accuracy of the device. Digital multimeters are usually more accurate than analog multimeters, so if you have the choice, it’s generally best to use a digital multimeter.

If you’re unsure of how to calibrate a multimeter, or if your multimeter doesn’t come with a calibration certificate, you can usually find the information in the user manual. Alternatively, you can contact the manufacturer of the device and they should be able to help you. [1], [2]


What are the symbols for microfarads?

The most common symbol for microfarads is the lowercase letter “u” with a small circle above it (µF). This is the SI prefix for micro-, meaning one millionth. So, one microfarad equals one millionth of a farad.

You may also see the microfarad symbol represented by the uppercase letter “M” with a small circle above it (MF), or simply by the uppercase letter “U”.

How do you read a microfarad on a multimeter?

To read a microfarad on a multimeter, you need to know the symbol for microfarads. The symbol for microfarads is mF or μF. To read a microfarad on a multimeter, you need to set the meter to the mF or μF setting. Once the meter is set to the correct setting, you can take your reading. Connect the multimeter probes to the respective terminals of the capacitor under test. The multimeter will show you the capacitance in microfarads.

What are the symbols on the multimeter?

The symbols on a multimeter can be confusing, but they are actually quite simple once you know what they mean. The most important thing to remember is that the red lead goes to the positive terminal, and the black lead goes to the negative terminal.

Besides that, multimeters also have symbols for different units of measurement. Among the most common are: volts, amps, oms, fards. Microfarads are usually represented by the symbol µF or mfd. You might also see the letter “u” as a substitute for the Greek letter mu (µ).

What is the capacitance symbol on a multimeter?

The capacitance symbol on a multimeter is the Greek letter mu (μ). This is the standard symbol for microfarads. The microfarad is a unit of measurement for capacitance. It is equal to one millionth of a farad.

The farad is the SI unit of capacitance.

It is named after Michael Faraday, an English scientist who discovered electromagnetic induction in 1831. One farad is defined as the ability of a capacitor to store one coulomb (C) of charge at a potential difference of one volt (V).


Microfarads are an important but often misunderstood unit of measurement. Most multimeters will have a setting for microfarads, represented by the symbol μF. To measure capacitance with a multimeter, set the dial to the microfarad (μF) setting and touch the probes to the capacitor’s leads. The reading on the display will be the capacitance in microfarads. Keep in mind that not all multimeter models will have an option to measure microfarads, so be sure to check your multimeter’s user manual before attempting to take a measurement.
