You should consider all driver choices available, and choose the driver that best fits your needs. Links to complete examples demonstrating how to execute the Measurement method and read the measured value are provided at the end of this document. Numerous Configuration VIs can exist, depending on the particular instrument. In Figure 7 , notice that the sessions to the DCVoltage interface and to the driver session are closed after they are used. The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument. Enabling autozero optimizes the instrument for accuracy, while disabling optimizes for speed.

For other instrument driver types, the examples will be available from the Application Examples subpalette from the corresponding instrument driver.
Feel free to write us at les. An example of how to access the help for the Initialize method is shown in Figure 9. Dottable properties have a blue glyph next to the property name. The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want.
Message 6 of 7. Converting variant data to an array See Also: Installing Software Refer to the instrument driver Readme file for detailed software requirements. Place a checkmark in the Show Creatable Objects Only check-box to display only objects that you can create.

The native driver has help for each of the instrument functons if you use the F1 help mechanism. Instrument Driver Organization Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.
You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram.
Selecting a dotted property. Message 1 of 7. Refer to the instrument driver help to determine the array data type.
They also have a CVI driver that can be converted. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument.
Viewing context help for AutoRange property. The Close VI- terminates the software connection to the instrument and frees system resources.
Using the Class Browser. Your on labvkew way to success Hope this helps.
Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. Using dotted agilejt and methods. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy.

I don’t know which driver you are using, so it is difficult to send you an example. The Status VIs obtain the current status of the instrument or the status of pending operations. Don’t be afraid of experimenting. Saying that it is straight forward is not what you want to read, right?
A dialog box appears, shown in Figure 1. Enabling autozero optimizes the instrument for accuracy, while disabling optimizes for speed.
