Fabulous collection! That Fluke 77 (series 1 and series 2) is fairly easy to re-cal. I made a short video of how I re-calibrated mine:


Much of my "training" came from MrModemHead's invaluable blog.

Just got my 8060A. Looks to be in good condition. Going to open it up this weekend and probably look at replacing the caps. I love the small form factor. Looks to be in calibration as well.

Not to worry, he's keeping an eye on us, last activity 31 May.

DR Taylor here...still alive and kicking. I've been doing a lot of G-jobs as well as some of my own projects. Just haven't had anything to post. I apologize to all those I promised 8060 User Guides to. I still have a small stack. I was just too lazy and too cheap to figure out how to mail them outside of the USA. So I will try to get to that soon as several projects are winding down.

One thing I've been wanting to share, and I don't remember if I mentioned this before. One main reason the LCDs on 8060s have lasted so long was due to having a separate polarizer. Most of the older systems had laminated polarizers and when they delaminated they would quit polarizing, causing black spots. The other reason the 8060 LCDs have lasted so long is that the Sharp SM4 micro had a very well balanced multiplex scheme that truly achieved 0 volts average voltage. This has prevented plating of the indium which you also see quite commonly on old instruments, even Fluke instruments. Not to mention, I truly believe that Sharp made superior LCDs to the ones that Crystaloid and LXD were making at the time. So these comments are limited to the 8060A and 8062A. The other 80 series (the granddaddy being the 8020) can have bad LCDs as they age. Of course any LCD will fail if it is cracked or the glass delaminates. It's really sad that I lost my big box of 8060 parts.

Thanks for checking in with us DR Taylor! Having just received my 8060A and using it for the first time, I must say this is truly a fantastic piece of gear. It is pretty impressive considering it is still quite capable so many years later. Also I didn't expect it to be this compact, which is great, after I restore it I think I am going to use it on a daily basis.

Thank you for designing such a great instrument!
