FLUKE 107 - absolute garbage lasted 2 years
<< < (3/13) > >>
Arhigos:
I believe there is cal button in the battery compartment. But if its 30% off you probably have some hardware failure.

Also, calibration mode is for service centers, calibration labs, etc. Not for regular owners.. That applies for any brand of test equipment
rsjsouza:
As others have hinted, carefully inspect the interior of your meter for any faults.

My experience with its sibling Fluke 101 was very disappointing and hinted to a lower degree of quality control. If the 107 is similar, I wouldn't be surprised that yours could have been a victim of the same reason.

Good luck in your repair!

Don't confuse sending something for calibration with having it adjusted. Sending something for calibration generally means that it will be tested and you get a pass fail with a detailed report. They will not adjust it for you. As others have said if it is 30% then something in badly wrong. If it were out by twice as much as it is supposed to be then yea maybe it needs a nudge, but 30% is faulty.

even from the factory its super suspicious if its 30% error. They will have 1% resistors in there or better and a reference that is pretty accurate.

I don't think it can even be lost cal data for 30%, it must be faulty cal data (bad chip giving bizzaro numbers), and I am surprised the program does not say "this is outside the bounds of adjustment for the chip".

I think it must be a analog problem. The cal just brings the cheapish analog circuit from say 5% intrinsic accuracy to 0.1% accuracy. 30% is extreme

the cal is a virtual version of the litle adjustment screw you have in your dial gauge. In this case the dial gauge is bent IMO

But hold on, just 2 years? Should it not be still covered by warranty?
