LOL, you can call as many non suitable meters as you want. To claim accurate measurment you need to use a proper multimeter or LCR meter with 4 wire measurment, and which is accurate enough in such low resistance range.
While there is only one result, 0.01Ohm.
There are no other results.
I wait for yours. ;)

You bypassed this, rather significant, point:

And still that would only result in measurement for one particular resistor from particular batch. No conclusions can be made about anything in general. For that you would need to buy tons of different resistors from at least hundreds of batches.

What is your sample size?

why are you making such a deal of it ? they are equivalent to wire, take it or leave it....

Yeah .... I've had enough of this.

tigr - believe what you will.

... and don't think my abandoning of this thread is any concession to you.  My involvement has been a waste of my time and now is when I walk away.

And now, if you're a man, you can apologize for your words.

Sure, after a really nice PM from you just now, harassing & cursing me with lots of "F" words, I still owe you, not a big deal.  ;)

So, please apologize me for "YOUR" thickness and stupidity.  :-DD

No problems. ;)

Your photo there are saved for collection.  >:D

Here, attached below your own photo, just added some more brightness for more clarity, this dude doesn't even know how to alter a photo properly, lets alone understand or measure low resistance. What an embarrassment.   :palm:

C'mon tigr, learn how to use photo editing 1st, then play with capacitor or resistors.  :-DD

That's not a zero, but ??, Ohm in Cyrillic.

Here I'm making two "totally" scientific measurements:

Top Instrument using my patent pending zero wire technique
0.000000000001 Amps current drawn

Bottom Instrument using my patent pending 4* wires soldered technique
0.000034 Ohms resistance

Now looking at your measurements Tigr I can see you are not accounting for drift, temperature, surface resistance, relative humidity and gravitational acceleration.

Therefore I suggest if you are going to explain further assumptions as fact instead start by explaining the science with a working hypothesis. Then allow peer review and if they disagree with your findings provide evidence to prove them wrong.

e.g.

Tigr: The Peak Atlas ESR 60 is measuring 0.01 Ohms
Doubter: But it says on their website the resolution is as fine as 0.01 Ohms but typically 0.02 Ohms
Tigr: (insert evidence backing up former statement)

or

Tigr: The Peak Atlas ESR 60 has 4 wire measurement
Doubter: But why do the wires in the images on their website have 2 single connection banana jacks and some came with only 2 wires?
Tigr: (insert evidence backing up former statement)

I stick to one principle.
I do not communicate with women in technical topics. :)
I give you the task to prove that there is not 0.01 Ohm.
If you do not prove it, then I'll tear you in front of everyone. ;)

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.

I often give them hour long phone sex repair sessions (1000s of kilometers away). Even without technical knowledge, if explained well enough often they are capable to fix stuff (of course not component level repair). Like PCB swap, replacing thermocouple and similar.

I'm always a little saddened when a member whom has acted civilly gets banned and too often it's those from another culture were English is a second language.
It's too easy to misinterpret their contributions and not all here are willing to work through to an mutual understanding with them.

Oh well, it is what it is.

I agree - and I did wonder about some choices of language - but working through to a mutual understanding requires effort from both sides.  Part of that requires a little humility and open mindedness, which was somewhat lacking on one side of this ledger.
