Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument. This example shows how to configure a measurement and take multiple readings. It has been busy for me for the past weeks, but here is the output. I get an error windows with the values the multimeter has acquired, I think. Action VIs are different from Configuration VIs because they do not change the instrument settings but order the instrument to carry out an action based on its current configuration. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument.

Message 5 of 7. Generally, you need to call the Wgilent VI only once at the end of an application or when you finish communication with an instrument.
Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. This example shows how to configure a measurement and take multiple readings.
If you are not very concerned with high speed aka you can wait for the data to be written to diskyou can just add the “Write to delimited Spreadsheet” to the while loop.
Message 2 of 7. The Status VIs obtain the current status of the instrument or the status of pending operations.
Does anyone have advice on how to log the samples at recieved from the multimeter in relative time, continiously for defined period of time. When all of these settings are set and the VI is executed the results will be displayed in the Measurements array indicator.
You also can use the Instrument Driver Finder to open example programs covering everything from analysis and presentation to using your instrument driver. Look at what you are measuring and see if it is useful. Most instrument drivers have menu palettes that include the following components.

The following figure shows this palette and some of the VIs and subpalettes that are shipped with it. After the instrument has been configured, the Read VI is used to read multiple points. This tool searches IDNet to find the specified instrument driver. Message 4 of 7.
Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. They also have agllent CVI driver that can be converted. It has been busy for me for the past weeks, but here is the output.
It would be extremely useful to show how to modify portions of instrument drivers for other use. The Initialize VI- agilfnt first instrument driver VI you call, establishes communication with the instrument. I get an error windows with the values the multimeter agulent acquired, I think. However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application.
It is a nice icon with red lettering and a tiny picture of the multimeter.
Your on your way to success Hope this helps. Message 6 of 7. The alternative to using the NI Instrument Driver Finder is to go directly to the Instrument Driver Network and search for your instrument driver there.
For other instrument driver types, the examples will be available mi the Application Examples subpalette from the corresponding instrument driver. Back to Top 2. Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy.

Message 34401a of 7. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram.
