Old Fluke Multimeters
drtaylor:
My collection of 8060s along with a first generation 8020 from 1976 and the very first production run 8026A. There are none older in the world as all of these came out of the first hard model runs. This is what we called the first units made by production combined with engineering.
The upper left unit is an IBM version. Upper center is a standard beige 8060A, but I stuck an IBM label on it (and no, I don't have any more, sorry). Upper right is my workhorse unit I've used for 30 years, still in calibration. Lower left was the original 8062 which is just a software limited 8060. Lower center is an 8026A/AA which used the 8060A TRMS chip. However, because it didn't have my frequency enhanced input structure, its bandwidth was significantly lower than the 8060. Last is an original 1976 8020A, the first product I worked on (but had little to do with the design). Just turned it on and it was in spec for DC which is the only precision source I have to test DMMs with.
I plan on selling the IBM unit in the upper left. I am replacing its caps and then it will be ready to go. At one time I had a box of about 40 8060A's all from the hard model run. I don't remember why they couldn't be sold, they were fully functional. It was just Fluke policy to not sell hard model runs. Anyway my boss at the time just said keep 'em. I used to give them away like candy and most went to other engineers and techs at Fluke. The ones you see are all I have left.
I'm looking forward to being on the Amphour on Monday. Stop by and say hi.

More of my old Fluke gear. Of these I only worked extensively on the 8922 Thermal True RMS Voltmeter (and the never released Power Supply). Some of these I obtained from other Fluke Engineers because they all wanted an 8060 in trade. A nice little bartering chip.
I absolutely loved working on the 8920/8922. This was the best education because of the complexity of the analog circuitry. The 8920 had banana jacks and therefore was slightly lower in bandwidth than the BNC input 8922. The 892x used a Fluke designed Thermal RMS chip. This was a sensor only and had to have a lot of circuitry around it.
The Fluke 7260A Counter on top of the 8922 was also mounted in Fluke's PTI (Portable Test Instrumentation) case. This was the medium size. There was one shorter and one taller version. They snap together so you can carry them. I don't know if this ever caught on. As I said in previous posts, getting heat out of it was a bitch. The last picture is the Fluke power supply concept unit. A project that was dropped. On top is possibly the only existing smallest height PTI case. I designed and built a remote display for connection to DMMs. I don't think Fluke ever designed anything into the smaller case, but I could be wrong.
Now where's that 8860?...my wife better not have tossed it!

I do love the color of the IBM model. I particularly like the 'customized' IBM label on the standard unit, one of a kind i suspect ;D

I've never actually seen a blue fluke from that generation. I'm curious if there were others

Well, there were 10000 of them sold to IBM. Probably a bunch of them somewhere.
On a different subject, I just found about 20. 429100 chips. This is the Converter used in 8020, 8022, 8010, 8012, 8024, 8026 and probably some I've forgotten about. If you need one to restore a vintage 3.5 digit Fluke DMM, drop me a line. They've been in anti static foam for 30 years, but chances are good they work.
Yay I found my 8860! Almost afraid to apply power. Now where's my variac?
