34401A LABVIEW DRIVER
Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument. Soon, you’ll combine them into your own vi and you’ll prefer using the multimeter through Labview rather than pressing the buttons. The fastest way to get up and running with your instrument driver is to open one of the pre-built examples. Generally, you need to call the Close VI only once at the end of an application or when you finish communication with an instrument. Message 2 of 7.

Feel free to write us at les. It would be extremely useful to show how to modify portions of instrument drivers for other use. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Using LabVIEW driver for Agilent A – Discussion Forums – National Instruments
It is a nice icon with red lettering and a tiny picture of the multimeter. Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument.
Works like a charm. An instrument driver is a set of software routines that control a programmable instrument. The Status VIs obtain the current status of the instrument or the status of pending operations.
In this example, serial communication is used. You can use an instrument driver for a particular instrument as is. Instrument Driver Organization Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.
Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital 3440a to a source instrument.
The Utility VIs might also include other custom instrument driver VIs that perform operations such as calibration or storage and recall of setups. The Close VI- terminates the software connection to the instrument and frees system resources. Get acquainted with sub-vi’s.
Don’t be afraid of experimenting. Back to Top 2. Enabling autozero optimizes the instrument for accuracy, while disabling optimizes for labvieww. In the following figure we have opened the Agilent Read Multiple Measurements.
labvied The Data VIs- transfer data to or from the instrument. Saying that it is straight forward is not what you want to read, right? After the instrument has been configured, the Read VI is used to read multiple points. 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.
The following figure shows this palette and some of the VIs and subpalettes that are shipped with it. The native driver has help for each of the instrument functons if you use the F1 help mechanism. You can create instrument control applications and systems by programmatically linking instrument driver Lxbview on the block diagram.
Message 7 of 334401a. The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want. The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument.

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.
34401z Active Software Boards: Message 3 of 7. This example shows how to configure a measurement and take multiple readings.
I hope this helps! Numerous Configuration VIs can exist, depending on the particular instrument.
