Man, your sense of humor is DRY. I'm used to TH-cam presentations where a clown comes out and hits the host with a pie if they make a joke. Keep up the great work!
That kind of humor is not so uncommon in Germany and is probably what makes many people that are not capable of getting it, give them the reputation of "not being funny"
I understand NOTHING in your videos and haven't for some time but every time you post a new video I stop what I am doing because you make it so fun to watch!
The godlike amount of work that has gone into this video is probably hard to describe. Congratulations on such a good channel. Enjoyed this longer video a lot :)
Marco, your videos are extraordinarily entertaining. All the puns, technical information, and slapstick are a joy to watch. I don't comment much on TH-cam videos, but this one was just grand. Thank you for taking the time to create it.
Now, that's the proper volt-nut stuff! I love these 5700 series calibrators. Too bad they have high-cost upkeep and now obsoleted for fancy LCD stuff... Dislike must be from somebody trying to buy one of these from epay cheaply... Expected prices after video now +1000% :D My heart still skips a beat watching Marco removing cans off oven hybrids. Memory of cracked unobtainable hybrid under it when cover went tilted still fresh....
You know when as a kid you get bored of your toy until your friend plays with it? Yeah, you just made me love again my Fluke 8502A. Same beautiful modular construction, the boards are not just shielded: they have a plastic, VHS-looking case with a door for access to the test points. Thing of beauty!
Круто! +1. Удивительно как для 88 года, такой многофункциональный девайс замутили флюковцы. Автор молодец капитальную работу провел по ремонту и наладке такого серьезного и сложного прибора!
As Paul of Mr Carlson's Lab has pointed out (a number of times), there are two different kinds of carbon composition resistors, an Allen-Bradley Hot Molded one with sharp corner ends, and then all the others with porous, rounded end packages. He and I are in full agreement that the Allen-Bradley ones never cause a problem, while all the others sooner or later do. And I would add that their trouble really comes sooner than later. The reason is that the hot molding process gives superior moisture protection. Moreover, their wire attachment is also good. I still keep saving my 1979 Allen-Bradley catalog that states "Allen-Bradley Style RCR resistors not only meet all requirements of MIL-R-39008 but also exceed the S level (best level) of Established Reliability of 0.001 % failure rate per 1000 hours." That tells the story. Except that A-B got out of the business, sorry.
would be interesting to see what Marco thinks about this

I don't know why, even if i don't have a clue what he does in these videos, i always find this astonishing. The world of electrical engineering is so captivating...
I absolutely love your videos, you are the one that has brought me to my new job as an "Elektromaschinenbauer" it isn't exactly what you do but it has the right balance between electronics and metalwork for me. Thank you reps! ^^
26:47 Marco you could make a 5 hour video and not kidding the majority of us would literally watch every second of it. I mean for me they are the perfect videos to watch instead of working on my actual class projects, thanks for the lower gpa ! (p.s. lmao)
Ah, there it is: another wonderful video in a long time. Had the thing been given to me, I wouldn't have the slightest idea what to do with it. Even if this thing worked right away. And yet I always enjoy watching and being shown that such devices exist and that there is at least one person in the world who knows what to do with them and who treats them well. Biegelehre.
Just so it's clear. The only reason people should be tired during these videos ist becase they're watching at 6am after being up the whole darn night. Love the longer Videos :) Edit: It's 6am and I've been up all night.
I physically flinched at that EEPROM removal clip. Painful. And man, I love your videos. My favourite channel on this page, I'm always looking forward to the next video. Grüße aus dem Badnerland.
No, no complaints on longer duration videos. Wishing you a laser resistance trimmer and a wire bonding machine before your RMS sensor fails. This is the first time i even heard of such a concept of measuring AC. Thank you for showing pinnacle of analogue electronics engineering..
I have a 5100B, haven't turned it on in a while, I'm afraid to. I wish I had the patience you have, but then, 50 years ago I probably did. Love it! Jim
Ich verstehe nur einen kleinen Teil von dem, was in dem Video an Elektronik passiert, aber es ist mir trotzdem eine Freude, so etwas anzuschauen. Videos wie Deine sind für mich das Besondere an TH-cam und ich freue mich, dass Leute wie Du, die von irgendetwas sehr viel wissen, ihr Tun anderen zugänglich machen.
I love this content. The sponsorship is honest and beneficial to the demographic audience, the memes are top notch and the editing is fabulous. All of this layered on top of the mans gigantic brain makes that good good I do like.
I immediately thought of "Mr. Bean: The Ultimate Disaster Movie" when I saw the cleaning rag moving towards those frail carbon keypad contacts. Poor Whistler's mother.
Awsome Video once again, and the precision measurement institute did a good thing donating to you the "scrap" equipment. Again with a huge amount of great humor! Congratulations.
The amount of research and knowledge being dropped second by second in a casual and Germanically indifferent way is gorgeous to see and hear. Even some random Counter Strike samples for light comedic relief. This machine has received so much love I'm sure it didn't expect! It would be cool to learn about some of the more "special" or "cared for" IC chips in this product (e.g all the ovenized ones...) what spec/design made them cool, if there is any modern day equivalent that just trumps them, etc. Also what the new cost for this machine might be, what a "fully functional" 2nd hand one one might cost, what your parts expense was for the repair, and what your hours of time invested was. The 35 minutes here as you said still seems shallow for the love invested in this project. It would also be great to hear what typical projects the original owner used this equipment for which made its cost worth it!
I used to use the 5700A in a cal lab back in the early 90's, it was one of my favorite pieces of gear, mostly because of the HP bus that let it be controlled remotely and some cal jobs could be done almost fully automatically, just had to change the setup. I don't recall the name of the controller but it had the cal procedures on 5 1/4 floppy disks.
@@droneforfun5384 its a multifunction calibrator used to calibrate voltmeters and multimeters, can output calibrated voltages both ac and dc, resistances and current also ac and dc.
I love everything about this teardown and repair. Really appreciate the extra insight into the methods used in this device. The RMS measurement makes so much sense.
In the 60's I remember working on some HP RMS voltmeters. The true way back then to measure RMS was to create heat with the AC signal. Then DC was applied to create the same amount of heat and the RMS voltage was determined from the DC. I can't remember what the module looked like. You pretty much said the same thing, the modules amplified the AC voltage, warmed an element, and the DC was applied to create the same heat. Don't recall, wouldn't be surprised it was in some kind of bridge circuit.
Wow, this was interesting. I used to use the Transmille 3200B and 3041A Calibrators. Seeing you attempt re-rejuvenation of this Fluke is impressive. Cheers Bud.
As always, this video of yours was equally enriching and informative as it was entertaining .. I simply love your sense of humor: pure dry German humor, way better than English humor .. extremely hilarious!
I like your "Der Terminator" approach to solving problems hands-on... although if I had to do the same as you do for my channel, I would need a life-time of sponsoring *grin* I actually expected you to say "I'll be back" at the end of your video, which in turn made me smile throughout :) Wish I had the same capacity for dry German humor... either way, you made an entertaining (long) video, vielen Dank
That whole machine is just beautiful and full of unobtanium parts. They were already good for one lifetime and in your care hopefully a few lifetimes more. The sheer engineering of all those boards boggles my (software engineering) mind.
Also, with regards to your component dismantling, I have gotten a TESLA (not the set-on-fire computer-on-wheels Tesla) BM 566A oscilloscope and in the manual for it, the process of replacing parts goes like this: To prevent damage to the boards, if a component is soldered on (which, fun fact, the transistors and chips aren't, they're socketed), snip off the leads as long as you can and solder the new component on the leads.
Hehe...memories! I remember when we got our older 5702.... new at the time, think it was 85. The 760 was our general purpose calibrator with the 332 being the dc gold standard for us. Some of the later 5700's got decent and approached the 335 dc standard. I wish I could get my hands on the old 5062 cesium beam we had. Ah the fun writing basic programs on a 1720 to control gpib instruments. Thanks for the memories : ) Oh, dilute the ip alot and a drop of dawn in liter of distilled water, you can clean those graphite pads...pencil eraser, no pressure just drag the smooth over.
Just saw this vid on yt sugestions, never heard of you before ) I enjoyed your fascination with English language as much as I did watching you 'find a purpose' for such restoration - "have several multimeters that need calibrating" he-he))
Yet another awesome video from you, watched it till the end and I still want more of this so I'm gonna watch the second part too now. Thanks for sharing great content like this here on TH-cam.
I work in a validation lab where we have two of these - one which failed. If you ever have a chance to acquire the amplifier for this unit, it is an amazing piece of equipment itself - increasing output current to 11A.
