Lessons In Industrial Instrumentation (for 2nd half of course) (Tony R. Kuphaldt) / CC BY 4.0

Online Class

Because of the Covid-19 Virus, TECH3232 will start via Zoom web based video conferencing at the normal class time by clicking on icon (below).

I will also be available during our lab time to assist via Zoom as well.

Classes will be recorded for future reference.

If you have never used ZOOM before, you might want to check out this Video Tutorial and the log in instructions. It is best if you have a mic. A Camera is not required, but I do like seeing who I am talking to. If you do not have a mic, you can ask questions via the Chat function as well. If using a mic, make sure you know how to mute/unmute (to ask questions) and ensure you know how to share your screen so I can see the issues you are having when asking a question on assignments.
