Albert, R1478 which should be 3.6 ohms measures 3.2 on analog, 3.6 on digital. R1468 which should be 0.6 ohms measures 0.7 on analog, 0.7 on digital. So not far off. I do trust my analog more

Very interesting, Albert. I do have a variable switching power supply that will put out either constant voltage or constant amperage with 0-30V and 0-10A. I'll have to try that! Bruce

Hi again, Dave. Here are the readings I just took across the test points: DCV, then ACV 110 = 87 225 50 = 37.5 90 15 = 12 22.5 5 = 3.5 4.2 -15 = -14.2

Hi Graham! Thanks for your contributions and supportive words! Yes, what I have learned has mostly been internet sourced, including the book available at allaboutcircuits.com, but I am only at

Sorry Ed this is on list, I couldn't find your email addy in your post. Dont know if it mentions Deoxit but may be useful. A google should find this, What Designers Need to Know About Low Voltage

I dint have those types if scopes. What do they look like ? Picture would be nice In matters of style, float with the current. In matters of Principle, stand like a rock. “. — Thomas

Hi Ke-Fong-Lin, I think Holger's solution of having them done by a PCB house was quite clever and it is inexpensive as well. There are a lot of franchise stores that make inexpensive signs. A simple

Hi Sean, David Holland beat me to the punch. The air conditioner extension cords sold by Lowes are a perfect solution once you shave off the little nubbin on the female end next to where the D-shaped

It is great that we have members who are able to provide so many things that make maintaining our collections easier. Hi Etienne, and anyone else who may want one of John's flexible

Oh no, not at all. Since you are a beginner with 'scopes I thought too quickly that you might also not have small value resistors handy. BTW I don't have a 475 myself and I sold my 465 long ago. For

Hi Albert, Are "low-homic" current sensing resistors different from any other resistor of the same rating? I checked my vast supply of components and found four 47K ohm resistors. By the way, that

Thanks for the suggestions everyone! I think either the air conditioner cord or one of the adapters will be perfect for what I want. Sean

I make my own. The Leviton No. 5269 fit the frames with no modification. They fit, barely but it is not a force fit

First, please respond directly to me only OFF-list, and only with relevant info. I don't want to get off on another huge Deoxit good/bad/whatever discussion, which has been covered many times. I would

I've used flying adaptor leads like

For instruments like the 114 pulse generator, 184 time mark generator, and more. Does anyone know of a good place to either get these power cables? I have one, that came with my Type 114. With a 184

Jeff, Excellent Project! I do not have one of these little scopes, but if I did, I would be buying this kit! Thanks for all your efforts. -- Michael Lynch Dardanelle, Arkansas

Hi all, I'm happy to announce that the Tek 222/224 Battery Replacement project is complete. I'm in the process of testing and shipping the first 25 orders from deposits received from folks here on

Thank you Roger and Albert for the excellent advice. I have the rackable 7603 and side-probing on the live system is not possible. But if the middle bay is left empty then signals can be brought
