What is a digital meter that can show waveforms called?

DVOM
DMM
GMM
DSO

The correct answer is: GMM

The digital meter that can display waveforms is known as a Digital Storage Oscilloscope (DSO). This instrument is specifically designed to visualize electrical signals and waveforms over time. A DSO captures voltage signals and represents them as waveforms on the screen, allowing technicians to analyze the characteristics of the signal, such as amplitude, frequency, and duration. This capability is crucial in automotive electronics for troubleshooting and diagnosing issues with various components that rely on electrical signals, such as sensors and actuators. In contrast, other choices refer to devices with different functionalities. For example, a Digital Volt-Ohm Meter (DVOM) and a Digital Multimeter (DMM) are primarily used for measuring voltage, current, and resistance rather than displaying waveforms. A General Purpose Meter (GMM) typically focuses on basic measurements without the advanced waveform display capability. Thus, the DSO stands out as the correct choice when it comes to a digital meter capable of visualizing complex waveforms.
