Fluke 87 repair

imix500 · 13th April 2006, 04:15 AM

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!!

Life time warranty on Fluke meters.

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]

dfdye, thanks for the tip. I was leary of calling thier tech support.
gengis, I thought that was just on the newer models? This is the original 87- with the smaller green display.
Thanks.

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!

It's such a fantastic meter, I was really mad at myself when I over-volted it.
So, this resistor that fried- I got from a site that it's job is overvoltage protection and is not a normal resistor. Is there such a thing as a fusible resistor?

With the newer ones you won't because they're auto ranging. There is a fusible resistor and the ones I've seen inside Flukes has to be de-soldered for replacement.

Replacing it isn't a problem. I just wanted to make sure I'm spending $7 on something that isn't actually a regular resistor. Well I guess I'll start with a new fusible resistor and fuse and see if the old girl measures again. Thanks!

The 87 is autoranging, and you can definitely fry it even with that feature. Just an FYI.
