  • Page 58: Graphing Multimeter (Gmm)

    Scope Multimeter Overview 5.1.2 Graphing Multimeter (GMM) Unlike the DMM, the graphing multimeter provides two channels for testing and plots a visual graphing line of the signal instead of displaying digital values. The GMM displays a signal’s measurements over time on a two-dimensional grid. This plotted graph is basically a graphical history (histogram) of the signal’s measurements over time.

  • Page 59: Lab Scope

    Scope Multimeter Overview 5.1.3 Lab Scope Similar to the GMM, the lab scope (oscilloscope) plots a visual image line of a signal’s measurements over time on a two-dimensional grid. The visual line that is displayed is commonly called a trace, and the graphical form created by a signal is called a waveform. Unlike the DMM, the lab scope allows you to visually see a signals waveform, which in turn allows you to see the strength and shape of the signal, as well as any noise that may be occurring on the circuit.

    Scope Multimeter General Reference 5.8 General Reference 5.8.1 Basic Setup Tips (unknown signal type) When conducting automotive diagnostics, situations may arise when you need to capture and analyze a signal that you are not familiar with, or know what the intended waveform pattern should look like, or even how to set the scope to acquire the signal.

  • Page 99: Using Known Good Waveforms

    Scope Multimeter General Reference As a default setting, trigger is normally off. The scope/meter uses internal circuitry to display a signal if present. However, in certain circumstances additional channel adjustments may be required, or the trigger mode may have to be turned on, for a signal that is present but is not displayed.
