  1. Physics 434 Welcome Toby Burnett [prof] Durmus Karatay[TA] Jason Alferness [Equipment] David Pengra [consultant]

  2. Preliminaries • class schedule. Lab often available (modulo Chemistry) • The text book – reference only • home versions of the program: uwin • Grading (lab reports/homework, project) • 2-person collaborations, same grade to each • The lab “report” is the VI: • Documentation (under properties) • Intro, discussion, conclusions • Save graphs with VI (operate | make current values default) • Comments in the diagrams, well-labeled front panel • CollectIt for turn-in of all assignments. • Project • Individual, or collaboration with clearly separate parts

  3. Course objectives • Basic concepts involved in experiment; 3 phases • Control • Acquisition • Analysis • Will use LabVIEW for all 3. • Electronics and Physics: a little • Computer interfacing: mostly just understand and use the NI USB module. (Project another story)

  4. Brief Schedule

  5. Explore the interface: Getting Started Activity • Run the “NI Launcher” (If 2013) • click “LabVIEW 2013 (32-bit) Manuals” • Or C:\Program Files (x86)\National Instruments\LabVIEW 2013\manuals • Open “LV_getting_Started.pdf” • (Also open ‘LV_Quick_Reference’ in another window, or print it out) • Read and follow the instructions in Chapter 1 until “Adding a Control to the Front Panel”

  6. Tools palette Shift-right click View | Tools Palette

  7. A quick exercise • Blank VI • Right click on Panel • Select a numeric control (knob?) • Click on panel to install it • Right click again, select numeric indicator, install • Open wiring Diagram (cntrl-E or Window | show block Diagram) • Use wiring tool to connect them (see how the cursur changes? • Run continuously

  8. Simple exercise, continued • Add a while loop on diagram (need the Functions Palette: show it, or right-click) • Right-click on input to the condition terminal, select “create control” a stop button just appears! • Now just run. • Try highlight execution (the light-bulb), probe (mouse near a wire) • Turn on the context help (cntrl-H), try tiling the windows (cntrl-T) • Add a second indicator, wire it in. • Use the labeling and color tools • Don’t forget the very important keys: cntrl-Z and Esc

  9. If time… • Continue with tutorial, start other activities, read the text and look at the assignment
