Re the 34461A I rate the 34401A I have as more stable.

Similarly, the 34401A I have is more stable than the 34410A.

I  wonder if you guys are as anal with your cars as you are with your DMMs, I mean, your cars have a 0 - 60mph time, do you always check on it looking for those horses that might have escaped over the years  >:D :-DD

No dyno visits for me. And the speedo...one car is 2 mph high, the other's 3 mph high, relative to a couple of GPS I checked them against. ^-^


 >:D The point I was making, is your car matching its claimed 0-60mph time, does anyone check it or are you all happy to accept the fact that its in the general zone  >:D :-DD :-DD

Started working through the DM502 assortment today. Though all were sold as "working" (of course), all but one fail at least one functional test (of course).  All have different origins, though two had Tektronix stickers on them.



First thing I noticed doing the physical check: three of the units had an oversized slow blow fuse in the current measurement line.  :palm:  The manual calls for a 2.5A fast blow fuse. Oddly enough, the current measurement function on these units isn't working. The fuse was blown on the fourth unit and when replaced, that function worked.

So I have one to put through the normal calibration and test procedure and three that are varying degrees of busted. The good news: these are pretty easy to diagnose and there aren't any really special parts.  For fun, I am going to try and do this project without using anything exotic other than the low voltage calibration source.
specialization is for insects.

Yea, I suspect the same. I may wind up mounting the replacement in a different location but space is tight. Luckily once it's set up you shouldn't have to touch it again.

@bd139, You certainly weren't kidding about the Heathkit C-3U that I snapped up for just £35. There's one on eBay now that's gone from an opening bid of £30 to £102 currently with another 11 hours to go. Mine was shown working, this is not shown working but is supposed to be. Seems I can double my money easily if I was to put it straight back on eBay as it is  :-DD :-DD :-+

Now you are headed down the Dark side proper. You were looking for Enclosures last night so checkout the Sheetmetal functionality of Fusion 360  :-DD

I attach a plaything I designed then Laser cut (you NEED one of them too ;) ) but if you want a custom look then it is worth giving it a go. Send your DXF off to a local sheetmetal company with a Laser or Plasma table and get what you really need not what you can get.

Fusion file is in the Zip below. Took me several hours and some youtube watching but it is fairly straightforward. Score lines on the cardboard are Laser engraves for crisp fold lines.
