Click The 'Get It Repaired' Button This is our estimated repair price for your DATA PRECISION 3500 DIG MULTIMETER based on previous repairs of similar DATA PRECISION 3500 units. Mark- Maybe I misintrepreted you before - is yours missing the IEEE module, or were you just saying you'd like to have it up and running? I originally asked because I tripped over a spare 8502A the other day, and thought about this post. I can't find a parts list for the 8502A online to see what Fluke lists as the interface module part number for the 8502A. On 8502A's I'm looking at with the IEEE option, the back of the IEEE module looks physically diffrerent from the one I have for my 8505A, so that plug in might not be interchangeable. This one, at least, I know is for the 8505A and 8506A. The one in my 8505A is #384057.įluke changed the part number structuring along the way, another number I see for the module is 716340. Some of the option modules can be interchanged between models, but not all. The IEEE interface was another one of the option plug-ins.
Fluke changed the part number structuring along the way, another number I see for the module is 716340. Fun to read about for now, it's still a very cool meter without it. If there was one piece of test gear I have that I would like to have the IEEE interface working on, it would be this multimeter- it opens up a whole new set of doors beyond what can be done on the unit locally.

That could be a factor why they are slow and inexpensive sellers. They are hard to buy used and know what you are getting unless the seller points out the included option modules. The options are confusing on these DMM models, as base units they came with DC volts only other than the thermal RMS AC was standard on the 8506A. The 8505A I have has the RMS AC plug in, but it is not thermal. I think the 8506A is the only thermal RMS model, in doing so it sacrifices being able to have the AC current shunt. In its heyday, it was probably the best you could get. I read somewhere that in the 70s, Fluke bought the rights to Data Precision bench meters, because their technology was (at that time) leading Flukes. And the VFDs could be rather flaky it would display 'A' (in 7-segment notation), rather than '8', for instance. I tended to lock it on one range, and use it to monitor a PSU voltage.
It was all relay-driven, as stated by Mark, above. On the downside, it was quite slow to use it did auto-range, but very slowly! it was fun to watch it clunk up and down its ranges whilst it did this.
Very, very accurate (ie, much higher accuracy than a modern Fluke, I don't remember the exact specs, but I did have a full manual which I sold with the meter) and its 100M input impedance meant it could do things that a modern Fluke couldn't. It was a real masterpiece of engineering.
It was kind of fun to play with, but virtually useless on the bench for any real work. The 5.5 digits also were somewhat of a novelty, as due to age the one I had lacked the stability it likely had when new, and the last two digits often just bounced around randomly.
It performs its magic with all TTL logic and discrete components, and there were around 8 relays in there. It doesn't have any current functions either, just AC/DC volts and ohms. Just due to its age, its not something you would want as your main meter to hold down the fort. I gave it to a friend who wanted the panaplex displays for something. Without the servce data it would be nearly impossible to troubleshoot as it was complex for its time, and I have enough other DMM's that I didn't want to spend the $20 for a manual for it. Prior to that, it was very accurate and a well made unit, although the autorange was real slow as it would click through a row of several relays. I had one that I got free from GE that worked for a little while but eventually blew something in its A/D converter.
There are a few places that have manuals for it on E-Bay for about $20 or so, that will be your only source for info unless someone here has the manual. Data Precision 3500 Manual 3,6/5 8508votes
