tigr, I think any hostility here isn't because we are disputing that you measured 0-ohm jumpers as "0.01ohm" or whatever - it is frustration that you seem to believe that if an instrument spits out a value, that its value is completely accurate. Please re-read my reply on the first page.
This forum is for electronics, and a huge part of that is test and measurement, so many here know about the accuracy of their instruments, how much they trust them, and how important accuracy (and precision) is in specific cases (in many cases, it isn't that important! like pull-up resistors). Here you appear to be measuring 0-ohm jumpers, as if they are some precision mystical component, when in fact they are even less interesting than standard 5% resistors, since we only care that their resistance is below a certain value so we can just assume they are like PCB traces, or wires, rather than their absolute value.
Other sources of frustration come from the idea that you can measure 10 milliohms accurately without 4-wire measurements. Once you get down to milliohms, the natural resistance of
ALL materials - ie: the connections you make to the component under test - become significant, and so require a way to mitigate that, cancel it out, or account for it. So there are folks who have replied who have careers making precision measurements that have been insulted by you simply posting a picture of an LCD displaying "0.01 ohms" saying "you measure it then!".
It doesn't matter how many you measure, or what instruments use use to do it (or how accurate they are) - I really don't think anyone gives a shit. I don't think anyone is going to measure their 0ohm jumpers because we don't need to know their resistance.
I provided a link to an article discussing the differences between accuracy, precision, tolerance and resolution which nicely explains the concepts.
edit: and... he's gone. I genuinely thought he just grossly misunderstood how the world works
It is something that appears to be on the increase (or I'm just noticing it more).. people blindly believing "what tech tells them" without really understanding why.
