The AEMC 8220 single-phase multimeter (also known as a multitester) measures electrical parameters and distribution network parameters including voltage, current, power, and harmonics; and monitors parameters of operating machinery including temperature, inrush current and duration of operation, distance of windings, and rotational speed. It is designed for use by technicians, control and maintenance engineers, electrical contractors, and educators. A continuity test confirms a circuit conducts electricity, and a diode test detects correct functioning of a circuit's diodes. Measurements include kW, kVAR, PF, DPF, kWh, KVARh, kVAh, and VA. The meter displays crest factor, peak, K-factor, and minimum, maximum, and average volts and amps. It calculates and displays watts, VAR and VA, power factor (PF), and displacement power factor (DPF) for single-phase and balanced three-phase systems. The meter can store up to nine sets of reading totaling up to 99 snapshots for volts, amps, power, and harmonics. Data can be transferred to a computer using the optical USB port and the DataView software (included).

This true RMS (root mean square) meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has an undistorted waveform, or nonlinear loads, such as electronic devices or motors, where the current or voltage has a distorted waveform. The meter has auto- and manual-ranging modes. In auto-ranging mode the meter automatically selects the correct operating range for the property being measured. The three-line backlit color LCD has adjustable brightness and contrast for use in a variety of lighting levels. The meter meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for Category III installations up to 600V, which covers items used with enclosed building circuit installations (such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply, Pollution Degree 2 for indoor use, and Ingress Protection certified IP54.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltage. Safety ratings are based on International Electrotechnical Commission (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

AEMC Instruments manufactures electrical testing and measurement instruments, including clamp meters, power quality analyzers, ground resistance testers, and data loggers. The company, founded in 1893, is headquartered in Foxborough, MA.
