NI-DMM includes several example applications that demonstrate the functionality of your device and can serve as interactive tools, programming models, and building blocks for your own applications.

NI Example Finder

The NI Example Finder is a utility that organizes examples into categories and allows you to browse and search installed examples. For example, search for "DMM" to locate all NI digital multimeter examples. You can see descriptions and compatible hardware models for each example or see all the examples compatible with one particular hardware model.

To locate examples using the NI Example Finder within LabVIEW or LabWindows/CVI, select Help»Find Examples and navigate to Hardware Input and Output»Modular Instruments»NI-DMM.

Common NI-DMM Examples

NI-RFSG Example Description
 NI-DMM Measure DC Voltage This example demonstrates how to acquire a single DC Voltage mesaurement. The measured value displays in the Measurement indicator. A Boolean control indicates if the measured value is out of range.
 NI-DMM Measure AC Voltage This example demonstrates how to acquire a single AC Voltage mesaurement. The measured value displays in the Measurement indicator. A Boolean control indicates if the measured value is out of range.
 Cont Acq&Graph Multiple Samples This example performs a continuous acquisition. The niDMM Initiatve VI starts the acquitision, and the niDMM Fetch Multi Point VI returns the requested samples. The data displays in a waveform chart.
 Read & Graph Waveform This example acquires a waveform using the niDMM Read Waveform VI. The data is displayed in a waveform graph.
