    The Fluke 80 series meters are spectacularly reliable. They make the argument for spending more for tools instead of spending again. My 87 is 36 years old, virtually all in the field. At one point, Fluke became aware of a problem that mine did not even have and sent me an entire kit of parts and directions to repair it. Satisfaction!

      I had a 70 series until it got stolen, dropped it off ladders, left it on hot machines, blew its fuses. Never had a lick of trouble with it until it got stolen with the rest of my tool kit. Family bought me whatever 80 series I have no, I've had it at least 20 years, tho it receives a bit less abuse now that I'm retired and also not running haunted house attractions in my spare time. ;) Never had a segment go dead or any other malfunction.

    Back in the 1980s I owned a manufacturing business making silicone connector strips. Zebra was my competitor. They always made an inferior and cheaper product. The deflection design is critical to the assembly from the display to the circuit board(s). Few manufacturers understood how to use such connectors for reliable performance. I provided holders along with my connectors and assisted with design in reliability. No one gives a shit about doing the right thing these days. It is all deiven by greed, not pride and reliability. Thank you China.

    • @spvillano
      @spvillano 2 місяці тому +2

      It all comes down to quality of components for anisotropic connectors and the slightly older subclass of elastomeric connectors and the board contacts/display contacts.
      Of course, cheaper is better to many, which holds down the costs, but also limits the lifetime of the product.
      I don't blame China because someone wants a $20 meter, rather than a $200 meter, as China didn't invent the market they're catering to, the buyers create that market.
      My first experience with these connectors and failure modes was with my old Beckman 310, where the plastic clips stretched, allowing oxidation to interfere with the display connections. Fortunately, the Fluke 77 had entered the market around when I was tiring of fixing the meter repeatedly.

So much so that I bought a 75 in 1989 or so for I think $119. Still have it and the box it came in. Still works, made in USA. Got in trouble for bringing it into work because it didn’t have calibration stickers on it and it wasn’t property of the company.

    I used to manage a business that manufactured electronic equipment and we all had Fluke meters. I honestly can say that I never encountered a problem with their LCDs. Unfortunately, our corporate overlords decided to get into the multimeter business and started to sell rebranded meters from China. We were no longer allowed to have the Fluke meters. The rebranded meters were junk. They were inaccurate, killed batteries quickly and had displays that flaked out like what you showed. To 'comply' we kept using the Fluke meters but whenever we had corporate visitors, I would collect the Fluke meters and the guys would display the junk meters on their bench. When the visitors left, they got the Flukes back.

    Those Zebra strips have always been a problem. What you did was the proper way to correct the problem. Some people will even go a little too far and take the Zebra strips off the LCD display which is a big mistake. Oils from handling Zebra strips can cause all kinds of problems. I used to replace them on all kinds of test equipment and learned the hard way.

The design was different, this used a ribbon cable (not the clip in kind). I squeezed it into the circuit board and the display worked great. To fix the issue, I placed a thin piece of plastic so that it would increase the pressure by a little bit, enough that the display is now perfect.

    Just a few weeks back I found this old R S Micronta digital meter. I'm not sure how I got, but I think it was a defective one someone gave me years ago. I thought OK fix it or throw it out. I have to much stuff and much of it is not longer of use or is junk. So I opened it up and put batteries in it and nothing happened when I turned it on. Dead I thought. So I looked at the insides to see if there was anything on the board worth saving. Somehow in that process when I pulled the board off I noticed that the display panel was not attached with any wires. Weird, I thought, then I saw where contacted the board. Hum, those metal parts in there look like they are tarnished. I cleaned them, and put the batteries back in and the display worked fine. so I have another volt/ohm meter. Sadly, I have trashed several meters in the past due to the display issues. Your video here now confirms what I found out. This is a new type of connection for me. In the case of this current meter, it was in my junk collection I bet more then 20 years. So that alone will have these things tarnish and stop working now that I found this new connection issue. Now for test leads that will last longer and still flexible.

    @douglas2lee929 2 роки тому

    Nice. You got lucky. The process of cleaning the zebra's and solder pad surfaces is always a crapshoot. Sometimes it works, sometimes it doesn't. So, you won this time. The amount of pressure against the strip is CRITICAL. Can't be too much, can't be too little. Sometimes the strips deform slightly or "shrink" slightly over the years, which can be enough to cause them to loose good contact. Even a few thousandths of an inch of dimensional change is enough for them to not work. So the shimming approach does sometimes work (but use only a TINY amount of shimming. If there is too much, the strip will get "squeezed" too much when reassembly, causing deformation, and the same poor contact problem). By the way, although Fluke no longer sells replacement strips (the woman in Service Parts actually laughed at me when I called--"Sir, your meter is 28 years old, we don't have parts for it anymore"), the strips for SOME models of Fluke DMM's are available from one or two places on the Net if you search hard enough. I bought a few for my 87's a few years back. Heartbreaking to consider trashing a $400 (more now) meter because of 20 bucks worth of silicone. Best wishes.

One of the PCB solder connections to the elastomer strips had rotten lead which didn't respond to contact cleaner. Scraped it with an Exacto knife then more cleaner. Works good now. Save your money and remove the 4 screws holding the LCD tower ass'y so you can examine the PCB contacts and clean them. If that doesn't help then try new strips.

Could it be they actually took the time to assemble them better? I do know when I purchased the meter (from Baynesville Electronics just north of Baltimore) the salesman told me the tested these by running over them with a truck and dropping them off a building to see if they survived. I own several other brands but when I want to be sure I always go back to the Beckman meter. The reliability is unparalleled. All digits are dark contrast on the background.

    Pencil eraser is a great contact cleaner, especially for battery contacts.

    If the circuit board zebra strip contact pads were gold plated there would be a lot less of the problem of fading LCD segments. But cheap is cheap. After cleaning BOTH the circuit board pads AND the zebra strip I apply Caig F5 Fader-Lube. Also with the push buttons. Works really well - my Fluke 77 and 23 multimeter displays stay reliable for much longer.

    Very helpful! Cleaned mine with alcohol on both the board and spongy pad and it made the segments stronger; less faint!

    What about a problem when lcd contrast goes really bad when battery discharges a bit? All other functions work well, but you have to look at the lcd screen at an angle to see anything. Is it that the manufacturer saved on some components which should regulate the lcd screen contrast?

    Interesting. I've got a few electronic devices that the same problem is going on. I'll have to try this. One of them is my Icom IC-735 HR rig. The very bottom of the display is blank.

    I'm curious how the rubber strip comes into play to push allow display on lcd? Is there light shining through the rubber strip? Does the rubber strip have to be perfectly aligned with slots/holes on the strip? etc

    • @dronillon2578
      @dronillon2578 Рік тому +1

      There is no light. It is about electrical contact. The rubber is basically a conductor (the black stripes are conductive). The same could be achieved with a ribbon cable or a bunch of individual wires. Each segment of the display requires one wire, plus one more wire for the common ground (or rather common plus contact).

    I clean with the alcohol first, then q_tip on some Caig Labs De-Oxit. You will likely never have the problem again.

    a pencil eraser to clean the pcb contacts before the use of alcohol will also help if the contacts are arced

    Should the rubber strips be cleaned aswell, as I believe they have contacts too that link contact from the circuit board to ones on the LCD.... and should the LCD contacts be cleaned too?

    It's probably less of a dirt issue as it is with Oxidation. DeOxit might work better if IPA doesn't fix the problem.
