    Q1: What is an oscilloscope multimeter?
    A1: An oscilloscope multimeter combines the functions of a digital multimeter (DMM) with those of an oscilloscope, allowing it to measure standard electrical parameters like voltage, current, and resistance, while also visualizing waveform signals for more detailed analysis of electrical behavior.

    Q2: How does an oscilloscope multimeter differ from a regular digital multimeter?
    A2: While a regular digital multimeter measures and displays numerical values for electrical parameters, an oscilloscope multimeter can also display real-time waveform signals, providing a visual representation of signal characteristics such as frequency, amplitude, and noise, which is crucial for diagnosing complex electrical issues.

    Q3: How do I interpret the waveform display on an oscilloscope multimeter?
    A3: Interpreting the waveform display involves understanding key parameters such as amplitude (peak voltage), frequency (repetition rate of the waveform), and shape (sine wave, square wave, etc.). The oscilloscope multimeter’s manual or user guide typically provides detailed instructions on how to read and analyze these waveforms.

    Tips: What are the main functions of a 3 in 1 handheld oscilloscope multimeter?

    A 3 in 1 handheld oscilloscope multimeter combines the functionalities of an oscilloscope, a digital multimeter (DMM), and often a waveform generator. This multifunctional device allows users to measure standard electrical parameters such as voltage, current, and resistance, visualize signal waveforms for detailed analysis, and sometimes generate test signals for circuit testing and diagnostics. This combination makes it a versatile tool for fieldwork, troubleshooting, and portable diagnostics.
