What Is a Multimeter?

A multimeter is an electrical measuring instrument used to test and troubleshoot electrical circuits and components. Depending on the model and its capabilities, a multimeter can measure voltage, current and resistance, along with additional electrical values. Electricians and maintenance technicians use these instruments to help diagnose electrical problems, verify circuit conditions and perform routine equipment checks.

Multimeters are commonly used in residential, commercial and industrial electrical work. They can help identify voltage problems, check continuity, measure resistance and troubleshoot electrical equipment. The functions and measurement ranges available vary by instrument, so selecting a meter suited to the intended application is important.

Digital and Analog Multimeters

Multimeters are generally available in two basic formats: digital and analog. Digital multimeters display measured values numerically on an electronic screen and are widely used for general electrical testing. Analog multimeters use a moving needle and calibrated scale to display measurements.

Digital multimeters are popular because their displays are easy to read and many models offer multiple measurement functions and ranges. However, the right instrument depends on the work being performed, the required measurement range and the features needed by the technician.

Common Multimeter Measurements and Features

Different multimeter models provide different measurement capabilities. Common functions include:

• AC Voltage: Measures alternating current voltage in electrical circuits and equipment.
• DC Voltage: Measures direct current voltage in batteries, power supplies and DC electrical systems.
• AC and DC Current: Measures electrical current when the meter and its leads are configured for the appropriate measurement and rating.
• Resistance: Measures electrical resistance in components and circuits.
• Continuity: Checks whether an electrical path is continuous, often using an audible signal.
• Additional Functions: Depending on the model, meters may also measure capacitance, frequency, temperature and diode characteristics.

Not every multimeter includes all of these functions. Before purchasing or replacing a meter, check its specifications, measurement ranges, input limits and safety ratings to make sure it is appropriate for the intended work.

Choosing the Right Electrical Multimeter

When selecting a multimeter, consider the types of circuits and equipment being tested. Voltage and current ranges, measurement accuracy, display features, available functions and safety ratings can all affect which instrument is appropriate.

For professional electrical work, the meter's measurement category and voltage rating are especially important. Instruments should be properly rated for the electrical environment in which they will be used. Test leads and accessories must also be suitable for the application. Never assume that two meters are interchangeable simply because they look similar or offer some of the same functions.

New, Used and Surplus Electrical Test Equipment

ESU buys and sells electrical equipment, including new, used and surplus products. We also help customers search for discontinued and hard-to-find electrical supplies. If you are looking for a specific multimeter, provide the manufacturer, model number and any important specifications so we can better understand what you need.

Businesses, contractors and electrical facilities may also have unused or excess electrical equipment taking up valuable storage space. ESU purchases surplus electrical supplies and equipment from businesses and other organizations. Contact us if you have multimeters or other electrical products available for sale.
