The NI ELVIS software, all created in LabVIEW has two main types: the soft front panel (SFP) instruments and a LabVIEW API, which are just additional LabVIEW VIs for custom control and access to the features of the NI ELVIS benchtop workstation.

When you begin the class, make sure to cover the following points: Introductions - Introduce yourself and give your credentials. Ask the students to introduce themselves to the class, describe what kind of applications they will be using LabVIEW for, and tell how long they have worked with LabVIEW (have they done the Tutorial?) This information helps you pace the course and know what concepts to stress. Know students’ interest and encourage them to provide new information or new question. Wish to know what they want to learn from this course. C
