Benchtop multimeters
Keysight benchtop digital multimeters enable you to characterize and debug devices, perform design validation, monitor key interfaces of subsystems during design, and ensure your products are properly tested to meet specifications. They are offered in four capability classes across three performance grades. Essential, our entry-level DMM, includes the DM5-class, providing 5.5 digits of resolution. Advanced includes the DM6- and DM7-class, extending up to 7.5 digits of resolution. Pro includes the DM8-class, delivering 8.5 digits of resolution and increased sampling rate. Portable includes the DM4-class, offering convenience in the palm of your hand. A comprehensive library of digital multimeter resources are available to help you find the performance grade and class best suited to your lab.

Frequently asked questions
A multimeter refers to a measuring meter that makes multiple types of measurements, such as alternating current (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and more parameters. A modern digital multimeter uses digital and logic technology to miniaturize and enable many features in its internal system. With digital technology, digital multimeters can have graphical displays, perform data logging and signal digitizing capabilities, programmability, and communicate with external devices.
A DMM is a versatile tool that can measure a wide variety of electrical parameters including:
- DC and AC Voltage (Volts)
- DC and AC Current (Amps)
- Resistance (Ohms)
- Continuity
- Capacitance (Farads)
- Frequency (Hertz)
- Temperature (via a thermocouple)
Accuracy and resolution are two different but related specifications of a digital multimeter (DMM). Accuracy defines how close the measured value is to the true value of the signal, usually expressed as a percentage of the reading plus a number of counts. It tells you the reliability of the result. Resolution, on the other hand, refers to the smallest change a DMM can display, often determined by the number of digits or counts on the display. A DMM may have high resolution but poor accuracy, meaning it can show very fine measurement steps but not necessarily the correct value. Ideally, a good DMM balances both high resolution and high accuracy to ensure precise and reliable measurements.
