FLUKE 107 - absolute garbage lasted 2 years
J-R:
Warranty is 1 year on the 107, at least in the US: https://www.fluke.com/en-us/product/electrical-testing/digital-multimeters/pocket-107

Thanks, that actually helped, I found some 4 contact pins for calibration.
There is a calibration window beneath the battery compartment, which accesses 4 gold plated pads in PCB
(WP9, WP8, WP7, WP6).
I have no idea how to use them though, does anyone know?
TomKatt:
I’m no expert, but I can’t believe the issue is as simple as calibration…. 30% deviation is pretty substantial - there must be a hardware fault somewhere. Even if you were able to correct the reading by some calibration routine, I don’t think that I’d ever trust that meter again.
EggertEnjoyer123:
As others have said, the chance that this is a software error is pretty much zero. I would not mess with the calibration at all.
You’ll have to open up the meter. If everything is off by the same amount, it is probably the voltage reference.
Arts:
The most common failures that I have found in Fluke meters involve the components in the input circuitry. Over-voltages/transients/spikes are usually responsible.
Oftentimes, these components will only act up after a certain voltage level is applied, but can also cause problems regardless of operating conditions.
I would think that this model has a very similar input arrangement as the usual Fluke meters, so I would suspect the following:
Varistors, Spark Gap, Input Resistors.
