Description: I put the switches back in and seem to have picked up a new problem. All of the "F" elements in the 7 segment displays is on bright and own't turn off when they're supposed to be off. However both switches that I cleaned and re-sprung the wipers on are now working flawlessly. So I'll have to do some more troubleshooting to find the issue in the next video, part 5.

- One of my my viewers made a very detailed paper and analysis of this unit here; ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/Data_Precision/8200

Oh here's Miss Keith's spiced Tea Recipe as promised in the video.
- Instant Tea (We us NesTea) 1/2 cup.
- Tang mix 1 cup.
- Lemonade mix (We Country Time) 1 cup.
- Ground Cinnamon 1 T-spoon.
- Ground Nutmeg 1/2 T-spoon. (Optional).
Put in a closed container and mix well.
Add 2-4 tablespoons in hot water. Enjoy! Personally I like mine sweet, I use 4 tablespoons.
Thanks for watching. Best Wishes & Blessings. Keith Noneya
