Every single topic gets spammed and hijacked by Jean's out of topic posts.
What a spammer! You would expect such an immature use of a forum from a teenager.
This forum has become a mess under his many unrelated replies, and "search" function is polluted with crap, crusades against SI or other useless/unrelated stuff.

But maybe as forum users, we should just "stop feeding the troll" and ignore him, since it appears that the recent two weeks ban was useless, and we can't expect he changes his mind today.
So my suggestion is to stop interacting.
Personally speaking I have stopped reading his stuff and downloading his documents. And I will return silent again after this reply.

I would like to add one more thing: for "non english" mother tongue users, his colloquial english is often confusing, to say the least.
It is confusing to me, at least (and I remember more than one user being puzzled, and asking to rephrase...). Colloquial and unclear statements, that's not the approach I would expect on a forum like this one.
I remember when I joined the forum some years ago, I always read his replies ten times while thinking "Damn I need to improve my english, here there is someone who is trying to teach me something and, stupid me, I'm missing the point due to my english skill".
After some months, I finally understood that my english was 10% of the problem :^P

IMHO, in his replies there is no true intention to "help" (as some may think), but only the intention to "show" (...wrongs... as we have all read recently, and as resumed by other users in this same thread).

See you.

Yes Uni, I understand and agree with your statement, I also think it is a waste of time to "regulate" this at an admin level.
On the other hand, since it is unlikely that we can change Jean's mind and way of thinking, I will personally stop interacting and simply ignore what happens.
Nevertheless, it should be noted that the forum will keep getting polluted and the "search" feature (which would be a very important feature of any technical forum...) is impacted.

There are even more SPRT [25.5 Ω] ... others fit in mother board.

Take care Alvaro ... Jean.

Neither, as usual. Sostenedlla y no enmendadlla.

Water TP is the water Triple Point, which is 0.01 C according to ITS-90. You can check that even on wikipedia. The water is for the thermal bath where the sensor is immersed, just like mercury or nitrogen.

PT100 is for Platinum, which has according to EN 60 751 a nominal value of 100.000 Ω at 0°C.


For what? The calculations you show are for the sensor manufacturer, not for use by the instrument engineer to calibrate the sensor. Or do you suggest that I do a liquid Hydrogen or Helium bath every time I'm going to calibrate a temperature sensor?

Best regards.
Alvaro.
