Selecting help for Initialize method. You should close references to all ActiveX sessions and interfaces when you are finished using them. Refer to the instrument driver help to determine the array data type. Using dotted properties and methods. In Figure 7 , notice that the sessions to the DCVoltage interface and to the driver session are closed after they are used.

Installing Software Refer to the instrument driver Readme file for detailed software requirements. An example of how to access the help for the Initialize method ifi-c shown in Figure 9. Links to complete examples demonstrating how to execute the Measurement method and read the measured value are provided at the end of this document.
The class interface changes and a new set of properties and methods are now selectable, shown in Figure 6. Place a checkmark in the Show Creatable Objects Only check-box to display only objects that you can create. In Figure 7notice that the sessions to the DCVoltage interface and to the driver session are closed after they are used. You should consider all driver choices available, and choose the driver that best fits your needs.
Viewing context help for AutoRange property. An instrument driver is a set of software routines that control a programmable instrument. Refer to the instrument driver help to determine the array data type. This list can be long, so you might need to browse for keywords that match the driver, such as the vendor name or “IVI”. Converting variant data to an array See Also: A dialog box appears, shown in Figure 1.
The Type Library list contains the type libraries for all the registered ActiveX servers on the system in alphabetical order. Automation Open and type library refnum. The block diagram should now appear similar to Figure 2.

Automation Open and Initialize method. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. Using the Class Browser. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument.
Selecting help for Initialize method. Dottable properties have a blue glyph next to the property name.

Selecting a dotted property. Select the same type library you selected for the Automation Open ivi-cc. Click on the block diagram to place the Initialize method on the diagram.
You should close references to all ActiveX sessions and interfaces when you are finished using them. Agilent IO Libraries Suite version This is typically the first interface in the list.
