Instructions / Notes:
- This LRC Ring Demo consist of:
- choice of no resistor or a couple of resistors to show critical dampening versus over dampening,
- a default 2.6 microfarad capicitor or 2.6 uF + 4.5 uF capacitance
- PicoScope computer interface
- Dell Laptop computer to be able to use the classroom projection system<

-
To perform the demo in its default set-up mode, the faculty member needs only to:
- select the laptop display icon on the lectern control panel
- then briefly push down on the red momentary switch.
- It may take up to 7 seconds for the data run to be displayed.
- This wait time in a classroom setting will seem like an eternity

Demo Staff: The 110v power cord for the table and the VGA cable from demo to the laptop connection on the lectern need to be connected before turning on the the laptop in the classroom.
-
Choose the LRC Ringing Icon once Windows has booted
- After the oscilloscope program comes on, resize the PicoScope window
- Next, click on the capturing mode button / icon, located at the lower left corner of the screen.
- Before leaving, look to the lower right corner of the screen and check to see if the capturing mode icon is on.
