Finally Marco got hands on proper 8.5 digit DMM and not all this drifty or self-cooking stuffs ;-). I begin to like my ADR1001's, need to finish up the public design. Soon (TM)...
Parts Per Million. Just like a percent (%) is total * 1/100, PPM is total * 1/1000000. So if he says there is an error of 5 PPM on the 10v range that means something that should read 10.000000 instead reads 10.000050 at worst. (I think)
Anyone else here have absolutely no idea what he's on about, and yet still watches all the videos? Like, I have no idea what this machine is actually for - why do you need a multimeter accurate to such precision?There's something strangely soothing about watching someone who clearly know what theyre talking about, even if I'd understand it just as well if he were actually speaking German
I was curious if you'd take a look at the ADR1001. I'm happy to see that you are. I had the same question regarding the SMT package. Analog Devices takes it very seriously in the data sheet and recommends mounting in on an "island" that is cutout from the main board. I guess a FFC board would work as well. I can't way to see that video.
15:37 - Beautiful, thats how a real "V8" should look like. You would have to adapt the SMD to DIL anyways i guess. Your sexy version with 2 L293D's is most likely 15 times more expensive though.. 😀 Which of course is in no relevance to the price of the full product.
Mach One had a solid video recently on how the ratio between shorter cable vs tighter loop changes with frequency ua-cam.com/video/TfzR3MxlgnQ/v-deo.html, re the potential “ground taking the scenic route through chassis / earth” issue.
Probably the most complicated digital multimeter ever produced. I wonder how much Fluke simplified the design for the 8508A and the 8558A? There is a Ukrainian 8.5-digit meter but the chances of getting one aren't particularly good. And I wouldn't even give Transmille's offering a passing glance.
@victorman2227 The ZIP Nauchpribor KM300. It is DC only but it has a built-in multifunction calibrator. Developed in the late 1990s AFAIK. Not much on them that I was able to find and that was years ago.
@@douro20 Thanks! I think ZIP Nauchpribor is from Krasnodar so its Russian. The website and the manual says that it's based on inductive voltage dividers so might be more of a voltage comparator (differential voltmeter) than a multimeter. I'm lucky to have a R3003 voltage comparator which is similar but manually operated.
Last time I checked, there were no consecrations on site, and anyway, it would be nude Norfolk men, can't have any old English men consecrating references! There are, however some 1281s inhabiting various cubby holes and technician friendly benches. There are also some sleeping or may be hibernating on dusty shelves....
8:30 *casually whips out another oscilloscope we've never seen before*
This is the latest keysight model. It has been promoted on other channels like electroboom eevblog etc
@redmist4963 I know, but we haven't seen it on Reps' channel before
This video is too short.
I will watch it twice.
@@tomking6006 all reps videos should be viewed at least two times.
weve been blessed with more marco reps

I have no idea what all the PPMs are about but I can’t stop watching

I get this sort of thing in concept but not in detail, so I enjoy learning things here and there as you work your way through it.
I think lots of us are here for the calming, dulcet tones of Marco's voice and the occasional hints of incidental hot smartness.
The Reps Semiconductor Division did an amazing job! I guess Fluke and/or Wavetek will flood you with multiple orders!
3:30 "met with a 2001 error" more like:
"I'm sorry, Dave. I'm afraid I can't do that."
Love the flying spaghetti monster! Super cool! Thanks for the entertaining and and hilarious commentary.
"flattery aside" That joke is flatter than the frequency response 😆
Actually a HP3456A is far more enjoyable to repair than this one, with lots of weird, mask programmed PLD chips and no real good manual.
I really like the idea of having a screw you tighten to enable cal mode, like JECS did with their engine control units to enter diagnostic mode.
Maybe having to loosen would make more sense- I can imagine some poor lab technicians tightening the screw "because it was loose" haha
pcb isolation cut-outs can be very based, if not highly practical

I can't resist. I have to watch your videos.
Sweet another video! Good to see you Marco
6:01 well thats a bit german part in meter
Thank you for everything you do.

I was about to ask about ADR1001, then you pulled one out, while i was writing the comment, lol
Anitmatter
The Westerlies - I recognized the style. Heard Dover from them in one of Becky Sterns videos and loved it since.
Is the owner Jeroen / Huygens Optics. He seems to have a faschination for voltnutting lately.
Thank you, awesome content.
Nice video as always.
Your video and the fact that I am currently looking for a good bench power supply reminded me, what happened to OSMU?
Excelent !!
What's your current thermal imaging solution ? Looks good !
marco is my ppm her0. :) weiter so.
excellent!
NNN(I) has been summoned
I was expecting "Also sprach Zarathustra" on the tower shot. Oh, well...
What a coincidence, I was thinking exactly the same!
Was Datron a German company in the past?
Amazing, I could actually understand some explanations of the repair.😂
11:20 No ground reference necessary for this measurement? 🤔 Or can you use the second channel as a reference with this scope?
I could have fix the meter but ChatGPT couldn't tell me how to get the cover off.
LOL @ 5:05 that was good :-)
So you left a different LTZ1000 in the meter?
only 20 minutes? u have changed marco
12:00 does it say … millideciBel?? 🤔 Why not decidecidecideciBel?
15:37 - Beautiful, thats how a real "V8" should look like.

0,56 Picofarad you say.... One sneeze and you have an exponent offset.
I already voltnutted this month :c
I work in metrology and this is almost all gibberish to me 😂. Still enjoyable though

Oh, nein nein nein nein nein nein!
I'm a whole day late to the party ;)
So many multimeters.
Probably the most complicated digital multimeter ever produced. I wonder how much Fluke simplified the design for the 8508A and the 8558A?
There is a Ukrainian 8.5-digit meter but the chances of getting one aren't particularly good. And I wouldn't even give Transmille's offering a passing glance.
A Ukrainian 8.5 digit meter? Please tell more!

@victorman2227 I believe it's also produced by one particular Ukrainian company as well.
Babe wake up, German ppm hunter dropped once again.
awawa 🥺👉👈
Who are you trying to convince ?
We all know you can let it go without trying to fix it.
lol...xD
In 7:51 the right side of the board is a little bit sus
6:55 that's why he said it's a low tolerance part
Agreed. Luckily Marco is a doubter of isolation slots🙏
