Do you guys all do this, or is it considered optional?  It's hard to find concrete info on this, it seems a niche topic and open to personal preference.  After measurement do you desolder the sensor with wick or a pump or just leave it on?  I guess it doesn't matter much either way, but if using AS5000 you are going to want to preserve the life of it as much as possible.

It does make sense though.. to recreate the same conditions that the soldering iron will be put under in real world usage.

The specific condition you would be recreating is using solder as a heat bridge. You can try testing the temp dry, and with a drop of solder as a heat bridge, and see how the temps compare. The solder shouldn't really stick to the sensor; if it is, you left it there way too long.

TomKatt:
Maybe it's me, but I've never relied on trying to dial in any specific temperature on the station...  It seems pretty straightforward to just get a feel for how the solder is flowing (or not) and turning the station up or down as needed.  I've never damaged a board or component from overheating.

Granted, I'm just a hobbyist and while I can appreciate the importance of accurate solder temps in a commercial environment, it doesn't seem to matter that much for home use.

And probably why I still like my old analog Weller with a dial - a twist is easier than a button dance.

KungFuJosh:
It matters. Especially if you have a digital station with the temperature drifting at some point. Lots of things are temperature sensitive. If you have the correct temperature dialed in, you can make a quality solder joint quickly without causing damage. If the temp goes low, and you're not aware, you can wind up lingering for too long and either cause a bad joint or damage what you're soldering.

Some solder will eventually stick to the sensor and the flux from the solder will evaporate and leave a nasty residue. Just add more fresh solder and immediately take it out with a clean soldering tip. Clean the the sensor from flux residue with isopropyl alcohol if needed. No worries.   :-+

I used Dave's Brymen BM235 to measure mine.  Seemed to match up.
