Last year i bought a replica XII pickup, and when it arrived it read 5.5ish on my multimeter, which was much less that the 7k that I'd asked for. I agreed a partial refund with the guy who was very good about it it and I put the pickup to one side with the intention of selling it down the line. I've now got round to putting it up for sale and have just re-done the reading for the ad and it's coming out at 6.89!!! I remember checking the reading a few times when i got it, to be absolutely sure that there was a problem before contacting the seller, so it isn't just a case of one dodgy reading. How can something like this happen? I haven't changed the battery in the meter and it's always worked and given readings that I've expected for many components, so I don't think it can be that. Could temperature changes be playing a part?

That's what she said.
Seriously though - that's very odd, especially if the battery isn't a factor. I've had a few variances in readings a few months apart for a pickup, but never to the magnitude of ~20%.
Good on you for getting back in touch with the seller though, a lot of people wouldn't.
DC resistance and impedance aren't the sane thing. Did you have it on DC OHMs's or an impedance setting ... basically an impedance reading is affected by the construction of a conductor, like a speaker coil or a pickup coil or an inductor for example.
It's not temperature ... you need to go very very cold for the resistance of a piece of wire to change.
I think this is probably it. I have a basic multimeter and always use the resistance setting, as I think that's all it has.

I don't think it's a reliable indication of output.

I can't explain such a big discrepancy as a reading of 5.5K from a 7K pickup though. Temperature shouldn't make that much difference, and I think that if the multimeter battery was on the way out it would stop working at all long before it gave that big an error.
