How Does a Multimeter Work?

A standard multimeter works by giving basic information about the power sources within your building. They measure current, resistance, and voltage, although more expensive models can measure capacitance and inductance.

Essentially, it diagnoses issues with the power supply to various electrical elements in the home. If you have a faulty switch, a multimeter can tell you where the problem is. It can even tell you whether a car battery is receiving a charge from an alternator.

Basic Functions

Voltmeter – Voltage

A multimeter measures the voltage, which is the pressure from an electrical circuit’s power source that pushes a current through a conducting loop. In short, voltage equals pressure.

Ohmmeter – Resistance

This is the measure of the opposition of the current flow in an electrical circuit. Resistance is measured in ohms, after the Greek letter for Omega.

Ammeter – Current

The current is the movement of charged electrons flowing between two points. Direct currents (DC) flow in a single direction, and alternating currents (AC) periodically change direction but can be controlled using a transformer.

Advanced Functions

Capacitance

Capacitance is the ability of a circuit or component to collect and store energy in the form of an electrical charge. Capacitors are not the same as batteries because the charge is stored as electricity, unlike a battery that holds it in chemical form. Most multimeters measure this accurately.

Frequency

Electrical frequency is the measure of the rate of oscillation and is rated in Hertz (Hz).

Temperature

This checks the operating temperature of the electrical wire. Some multimeters have this as an advanced feature, although it is less common in the home/hobbyist models.

Pressure

Electrical pressure is also known as voltage, and multimeters measure the pressure to see how much power reaches the component.

Inductance

Inductance is the ratio of voltage to the rate of current change. The multimeter measures the geometry of the current path as well as the permeability of nearby materials. Many factors influence inductance, such as separations of the turns and the shape of the coil.

Conductance

Conductance is the frequency at which a current or heat passes through an object. It is the opposite of resistance.

Types of Multimeters

Essentially there are analog and digital multimeters. One uses a needle on a dial to give the reading, while the other has a digital display and shows the values in numbers.

Analog

Analog multimeters are older technology. The first multimeters were analog. The needle moves along a dial showing the power values for each specific element.

Analog multimeters incorporate a microammeter, measure the duty cycle as well as the current, resistance, and voltage. Some analog meters measure transistors and capacitors, although the resistance of these meters depends on the sensitivity and the range chosen.

One advantage of an analog meter is it can handle sudden changes, but they are typically limited to reading amps, volts, and ohms.

Analog meters rarely fail and have very low input, but they are also limited because you have zero scope to adjust them.

Digital

Digital multimeters are the most common by far. Almost every model sold is a digital variety. The display shows numbers and values in an LCD format.

Digital multimeters have 4 elements:

  • The display.
  • Buttons to select different functions.
  • A rotary switch for different measurements.
  • An input jack for the test leads.

Digital meters are easier to read and much more accurate. If you use a multimeter all the time, a digital version is better because it is less susceptible to moisture damage.

Digital multimeters are categorized in 4 ways:

  • Category I.
  • Category II.
  • Category III.
  • Category IV.

Key Features to Look For

There are so many factors to consider when shopping for a multimeter. We narrow down the most important features to look for so you can make the best choice.

Specifications

You can substitute the word specification for capabilities. Make sure you choose a multimeter with a CAT safety rating and can accommodate more current than your power source can withstand.

Another feature to look for is True RMS, which stands for Root Means Square and is far more accurate than an RMS device when measuring AC.

You should also consider internal blast shields, shrouded banana plugs, auto shut-off, and a large backlit screen.

Accuracy

Accuracy is the key to any measurement, and your multimeter is no different. Check it reads both AC and DC. You should get the model with the narrowest permissible error limits.

Resolution

The resolution offers a meaningful reading and the best resolution of the measurement. It is the smallest increment a device can detect and display. You can find the resolution listed in the device’s specifications, but almost always as the maximum resolution.

This is the smallest range that the meter can read on the lowest range setting. You can improve the resolution by reducing the range setting, providing the measurement is within the set range.

Input Impedance

Input impedance is critical if you want to avoid inaccurate readings. Multimeters are robust tools and should provide precise measurements that are easy to read. A low impedance mode prevents “Ghost voltages.”

Temperature Measurement

Look for a multimeter that has a dual differential temperature measurement function. This is a perfect choice if you have a thermocouple replacement or monitoring need, especially when fixing water heater problems and repairing HVAC systems.

The dual differential allows you to measure two different readings simultaneously.

Energy Capacity

To avoid damage, it’s a great idea to know what the energy tolerances are for your multimeter and the circuits you are preparing to work on.

Frequency Measurement

Some multimeters measure the current and voltage within a frequency range.
