Weird coincidence. Probably about while you were post that, I was trying to fix mine. It's a bit different though, it has a slider switch and push button. I think it was the first meter I bought. But it quit working properly many years ago.
The obvious problem was that when I set it to the ohms function it just shut off. I figured it was a simple fix, just take it apart and clean the gunk out of the slider switch and it will be fine. I did that, and also cleaned some crud off the battery contacts and figured it would be fine.
Put it back together and now it remains on in the ohms position, but I tested it by hooking it to my bench power supply set to 2.5 volts and it read 1.2 V or so. Then I found that if I pressed on the front in just the right spot it would jump up and read 2.5 volts like it should. OK, cracked solder joint or something. Except I inspected every joint under my binocular microscope from several lighting angles and couldn't find a single joint that looked bad.
And in the process of taking the thing apart several times, since you can't just test the circuit board out of the case, I managed to break several of the tabs that hold the case together. Tried to glue them back and had an issue with a pressurized super glue tube that belched out everywhere when I opened it, cleaned up that mess, tried to glue the tabs back, resoldered a few joints on the board in the area where pushing on the case made it work, and no dice. Still reads wrong unless I push hard right on where it says "meter." Which is no where near any of the inside switches or contacts for anything. It's actually right where one corner of the big IC is on the circuit board. Figured maybe I could resolder all the pins of the IC in that area, but I decided I had already spent too much time on fixing something I don't need and was taking up way more time than I expected.
I had one of the 22-169s like this one I bought after the 22-171A; it was a total piece of bunk. The selector slide was "jiggery-doo" flaky from day one, eventually it got to where it would only work at all with a binder clip squeezing on the lower right corner by the lead exit. I took it apart several times and tried to fix it to no avail; eventually I came to the contusion that the fault had to be in the COB under that blob of resin, so declared it a lost cause and used the leads & case to fix up my 22-171A, which continued to be my "tool box meter" for many more years.
Whenever you post this, I can hear the piano riff. (Makes you wonder what else has been embedded into your brain.)
https://youtu.be/VOaZbaPzdskI know, right? Same thing with School House Rock and Sesame Street... whenever I my kids are counting, I hear it in this tempo... and of course I teach them to count to twelve, not ten...
Yes... the man who imagined a world connected by communications satellites before Sputnik, and who brought us "3 Laws Dependable, 3 Laws Safe!" The man was a visionary... and of course, as such, found himself constantly bound by Cassandra's dilemma.

If only we applied those 3 laws to.. our laws.
Thank you for the reference. I had never heard of Cassandra's dilemma or if I had studied it 45 years ago in school, I had forgotten it. Nice tidbit of mythology to know. I really need to read a refresher book.
I find myself in a near-constant state of flux between being Cassandra and being Diogenes... sometimes both at once.
Trying to teach your kids right from wrong in the
Age of Global Deceit will do that to you.
Clarke, Heinlein, Asimov, Bradbury... the futures they envisioned encompassed the best and the worst of humanity. A well-rounded education must include them all.
A few years before he died, Asimov conspired with James Burke and Jules Bergman to present a series of lectures at NASA when I was still young; the transcript has been a staple of their library since. Amazing how over 30 years later, their insights into humanity and the future are as relevant as ever:

I, Robot below. Here is where I found it:
http://www.ttu.ee/public/m/mart-murdvee/Techno-Psy/Isaac_Asimov_-_I_Robot.pdfI ordered my DE5000 3 weeks ago. Got a notice this morning that states:
"Your item has been processed through our facility in ISC NEW YORK NY(USPS) at 5:21 am on October 21, 2018."
I googled about it and all it means is that it arrived, not departed from. (Government double speak at work?) God alone knows how long it will linger there.
Anyone else ever have it take this long to get a package from Japan?
Yeah, mine drove me crazy; it's like once it got to the US it went from "1st Class" mail service to "Last Class". Took 2 1/2 days to get from Japan to LA; then 10 days to get 1500 miles from there to me. And the same exact
tracking.
Be patient; it'll get tooya. And you'll be amazed at how much tech they stuffed into that little box.
