multimeter
Electrical diagnostic tool
A multimeter is an electronic measuring instrument that combines several functions in one device, typically measuring voltage, current, and resistance.
Most multimeters can switch between these modes and display readings on a dial or digital screen.
Electricians and technicians use them for diagnosing circuits: The multimeter showed the outlet was dead.
