content: Hello Everyone.So i have been hanging around this forum for a while now. And the respect i have gotten for this community is immense, and the level of expertise! You guys you are the real MVPs.Anyways, I thought i should do a proper introduction, as I am not a fan of introducing myself the second i would need some help, I'm doing it on a separate post in newbie section(the forum should really get an introductory section).I am a 33 year old electrician, and done a lot of electrical in a assortment of fields. My name is Trond, hence the username, jobless and have started up university education as an electrical engineer. Currently on the first year, had to do pre courses the year before, and what a bottomless pit that was. Well not quite jobless btw. I work, but seldom, as an electrical engineer within a small company that uses VDF's and synchronous servomotors to implement in niche areas. Some will definitely do good in terms of sales. Well, enough about that.Last year i started to build my laboratory. And what i ride that one has been. I have for many years wanted myself an oscilloscope, but have not had the justification. But last year i bought the Siglent SDS 1104-x, and I am quite satisfied with that, and from that point it just started to build. My commute to university is about 2,5 hours each way, so having the laboratory equivalent at home is certainly of great convenience, so the foundation for the justification to get some lab equipment just got heavier. AWG, PSU and a multimeter, a benchtop ofc. Never been happier. And this is a bit weird, never have i had such a fondness for material goods before. New computer, the happiness about that dies away shortly after, but lab equipment ? always a joy just to watch it.I also got good connections with my peers at uni. One of them could tell me they got a Fluke 43B, faulty, with an extreme amount of horizontal lines. I did some research, found that anisotropic conductive film have issues through time, and the Fluke 43B isn't actually a newly released model either. I've been in that meter 4 times to find the courage to use a sufficient amount of heat. And lo and behold it does not delaminate any more. Just for future referanse i discovered that you could actually se colour or opacity variations on the ACF film through a tiny sliver past the connection point of the vertical flex cable. Apply heat, use a flathead screwdriver, with electrician tape on the end to reduce material hardness, to ensure the opacity/colour variations seize to exist. It takes some time to get used to see this. But if you can look passed the glass you can see where connections are good and bad. Good luck to everyone that has this issue. It is also related to the Fluke ScopeMeter 123, Dave did one on a 199 i think.This week a Fluke 87IV will come by mail. A got a great deal on it. Its been stored away for a while with the batteries stored in it. Pins have been corroded away. I got a good deal on it, at least that's what i think. 85USD included shipping. What worries me though is the corrosion. I hope the acid haven't seeped onto the board. I was thinking of doing a repair/clean up, and post it on here, but not until i properly introduced my self.Thank you so much for taking your time to read. See you around the forum.Pictures of the Fluke 87IV is attached, as it was shown in the description for the ad.

content: Just clean out the corrosion. I think it would be fine.

content: For the 87IV its the same as an fluke 187 or 189 ...I think a clip is broken on the picture ?You can find the battery clips kit for a low price on ebay, if the meter function well, its a good deal to prolong its life
