I just downloaded the file again and followed the steps I described earlier. Back to Top 2. Works like a charm. It is a nice icon with red lettering and a tiny picture of the multimeter. I hope this helps! Open a blank vi.

How to Use an Instrument Driver in LabVIEW Tutorial – National Instruments

Message 1 of 7. You can use an instrument driver for a particular instrument as is. Has a 3 Application Examples and a “Getting Started” one which should get you on your way.

The Data VIs- transfer data to or from lavview instrument. Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument. Generally, you need to call the Close VI only once at the end of an application or when you finish communication with an instrument.

Works like a charm. Look at what you are measuring and see if it is useful. Message 3 of 7. These VIs include the majority of the instrument driver template VIs, such as reset, self-test, revision, error query, and error message. Get acquainted with sub-vi’s. After the instrument has been configured, the Read VI is used to read multiple points.

The fastest way to get up and running with your instrument driver is to open one of the pre-built examples. You also can use the Instrument Driver Finder to open example programs covering everything from analysis and presentation to using your instrument driver.


The Action VIs – initiate or terminate test and measurement operations, such as arming the trigger system or generating a stimulus. The best way is to open the sub-vi which appears to be what you want to do and run it. The Utility VIs might also include other custom instrument driver VIs that perform operations such as calibration or storage and recall of setups.

The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. Additionally, it can perform any necessary actions to place the instrument in its default power on state or in another specific state.

Message 2 of 7. Feel free to write us at les. I just downloaded the file again and followed the steps I described earlier. Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.

Finally, the Simple Error Handler is called which indicates whether an error occurred.


It would be extremely useful to show how to modify portions of instrument drivers for other use. Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital patterns to a source instrument.

The alternative to using the NI Instrument Driver Finder is to go directly to the Instrument Driver Labvieq and search for your instrument driver there. Don’t be afraid of experimenting.

After you call these VIs, the instrument is ready to take measurements or to stimulate a system. The Utility VIs- perform a variety of operations that are auxiliary to the most often used instrument driver VIs.

From the block diagram you can see that the instrument is first initialized with the Serial Configuration and VISA resource name specified on the front panel. Message 7 of 7.

Les Hammer Complete 34410a. I don’t know which driver you are using, so it is difficult to send you an example. The following figure shows this palette and some of the VIs and subpalettes that are shipped with it.
