What is a DMM (Digital Multimeter)?

Though DMM can mean a lot of things, including “don’t message me,” a popular brand of climbing gear and an entertainment e-commerce site, the most common meaning of DMM is digital multimeter. A DMM is a standard test and measurement instrument used by electrical engineers and technicians to measure multiple electrical stimuli, including voltage, current and resistance. It combines the features of a voltmeter, ammeter and ohmmeter, and is used to verify the state of a system or circuit for safety purposes.
