Feel free to write us at les. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. I get an error windows with the values the multimeter has acquired, I think. Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. I am using the Agilent A to measure DC current, using the default example.

The Utility VIs might also include other custom instrument driver VIs that perform operations such as calibration or storage and recall of setups.
Overview of Instrument Drivers An instrument driver is a set of software routines that control a programmable instrument. An instrument driver is a set of software routines that control a programmable instrument.
It is a nice icon with red lettering and a tiny picture of the multimeter. The Close VI- terminates the software connection to the instrument and frees system resources.
There are many other triggers that can be used to stop the acquisisiton time after acquisition started, X of data points, etc. I’m not sure about instructions, but if you installed the driver and opened the library, you will get sub-vi’s which have a particular application purpose.
I am using the Agilent A to measure DC current, using the default example. I don’t know which driver you are using, so it is difficult to send you an example.
The Configuration VIs- a agikent of software routines that configure the instrument to perform the operation you want. 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. Message 4 of 4.
The native driver agjlent help for each of the instrument functons if you use the F1 help mechanism. Has a 3 Application Examples and a “Getting Started” one which should get you on your way.
Works like a charm. For other instrument driver nii, the examples will be available from the Application Examples subpalette from the corresponding instrument driver. Finally, the Simple Error Handler is called which indicates whether an error occurred.
Get acquainted with sub-vi’s. Most instrument drivers have menu palettes that include the following components. Message 2 of 4. Message 2 of 7. Numerous Configuration VIs can exist, depending on the particular instrument.
I just downloaded the file again and followed the steps I described earlier. Most Active Software Boards: Enabling autozero optimizes the instrument for accuracy, while disabling agklent for speed.
This agilfnt searches IDNet to find the specified instrument driver. The following figure shows this palette and some of the VIs and subpalettes that are shipped with it.
I download directly from Agilent’s website. LabVIEW instrument drivers simplify instrument control and reduce test program development time by eliminating the need for you to learn the complex, low-level programming commands for each instrument. It has been busy for me for the past weeks, but here is the output. You can create instrument control applications and systems by programmatically linking instrument driver VIs agioent the block diagram.
I hope this helps! The method I show assumes you add a Timestamp control to the Front Panel where the operator is inputting a time in the future when the test will stop. Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.
Soon, you’ll combine them into your own vi and you’ll prefer using the multimeter through Labview rather than pressing the buttons.
