ohmmeter
This term is a technical compound combining "ohm" (the unit of electrical resistance) and "meter" (a measuring device). It is used exclusively within the fields of electrical engineering, physics, and electronics repair. In professional settings, it is often categorized as a specific type of multimeter, which combines the functions of an ohmmeter, voltmeter, and ammeter into one device.
Because it describes a physical tool, the word is used in a literal sense. It lacks metaphorical extensions or idiomatic usage. When discussing the act of measuring resistance, technicians may refer to "taking an ohm reading" rather than "ohmmetering," as the word does not commonly function as a verb.
