Hello all, has anyone ever put too much voltage into thier 87? Well I did.
Understandably it is not acting right after the fact. I have already spotted what appears to be a resistor thats toast. I've gathered from google that it is some special "fusible resistor".
Aside from fuses, what else could have I damaged? Does fluke sell replacement components direct?
Thanks!

I am not sure if they sell components directly, but they certainly service thier meters, and parts are readily available elsewhere if nothing else. If I were you, I would call their tech support line and ask them directly. The last time I had a problem with a meter in my lab they were more than helpful!!
Not all of them. I have one that missed that deal by a few years. 
It was a REALLY nice one too, but I can't remember the model off of the top of my head.
[edit] Oh Schnikie! It was an 87!!! I looked it up, and the difference between the current 87V: "The 87V operates very similar to the classic 87, but with more problem solving power, safety, convenience and impact protection." And the lifetime warranty!![/edit]

Yep! That's the one!! I have a busted one of those in my drawer at work! Good luck getting yours fixed. I just got a new one when I found out what was wrong (and that I could upgrade during a special they were running, but I think that is over now.) The new one does have the warranty, though!
lol, indeed!!!! Next time get yourself a good 10X scope probe and save the repair! I have a buddy that had to make a 10,000X (I think) probe for measuring the potential at a mass spectrometer ionization source. The fact that it had to be encased in oil was more than amusing to me!imix500 said:
But at least he didn't fry his detector!! Anyway, good luck with getting the Fluke fixed.
Yeah a high votage probe is not a bad purchase idea. They are cheap on ebay.
Blues, hehe I agree, although I wouldn't doubt flukes voltage rating there.
To my defense I was measuring around 1200v, just over the limits of the meter- not off of a flyback or anything, it was not in my hand when I was metering, and it was by accident. Thanks!

I've been repairing and bulding my own laser power supplies for a few years now. I was working on a supply consisting of a bank of 16 450v 3400uf capacitors among others.
I was reforming some large oil energy storage caps for the firing circuit and I forgot the meter was still connected as I was bringing the voltage up (I use a surplus electrophoresis supply for reforming)

dfdye, hehe. Excellent collection. I myself only have a working SSY-1 system in my apt. I have a huge dye laser head I'm hoping to eventually convert to nd/yag. Now I just have to find a ~1/4" x 12" rod, two lamps to match and 1" optics. Eh, it was $30. Aside form that a bunch of yag power supplies and parts, and 4 or 5 large thyratrons. My father is into visible light gas ion (argon, mixed gas) large frames. He's got a Lexel 95, Coherent I-90, and a SP 2012. Fun stuff.
willyhoho, will do. Forgot these meters use mov's. I wish schematics were find-able for these meters.

Just an update, got the service manual from Fluke. I was really suprised they have them for download.
After a thorough evaluation of the front end of the meter, I'm replacing the fusible resistor R1, both varistors RV1 and RV2, the thermistor RT1, and a cap C1 that was damaged by the varistors when they blew. Basically the entire front end protection except for the spark gap. It appears to still be a spark gap.
I bought the parts directly from fluke through thier estore. Also picked up an extra set of fuses. I thought $40 for those original replacement parts wasn't bad considering what it might cost to send it in for repair.
