Converting variant data to an array See Also: Links to complete examples demonstrating how to execute the Measurement method and read the measured value are provided at the end of this document. Dottable properties have a blue glyph next to the property name. In Figure 7 , notice that the sessions to the DCVoltage interface and to the driver session are closed after they are used. A dialog box appears, shown in Figure 1. Click on the block diagram to place the Initialize method on the diagram.

Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. Select the same type library you selected for the Automation Open refnum.
Dottable properties have a blue glyph next to the property name. Refer to the instrument driver help to determine the array data type. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.
The block diagram should now appear similar to Figure 2. Figure 10 shows the Context Help window for the AutoRange property.
Dotted properties are a shorthand alternative to cascading multiple Property Nodes that return interface references needed for wiring properties and methods specific to a given interface.
In Figure 7notice that 34401w sessions to the DCVoltage interface and to the driver session are closed after they are used.
Using the Class Browser. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. Installing Software Refer to the instrument driver Readme file for detailed software requirements.
Using an IVI-COM Instrument Driver in LabVIEW – National Instruments
Viewing context help for AutoRange property. The class interface changes and a new set of properties and methods are now selectable, shown in Figure 6. The Type Library list contains the type libraries for all the registered ActiveX servers on the system in alphabetical order. Place a checkmark in the Show Creatable Objects Only check-box to display only objects that you can create. This is typically the first interface in the list.
You should consider all driver choices available, and choose the driver that best fits your needs. An example of how to access the help for the Initialize method is shown in Figure 9. Selecting help for Initialize method. An instrument driver is atilent set of software routines that control a programmable instrument.
