saying 'in range' without specifying what range is.
OK this is a report of a rather macabre experiment I conducted ... it is not for the squeamish.

A while ago I pulled an applicator apart because ... that's what one does. The applicator has an insertion needle that guides the sensor filament under your skin.
So when my sensor fell off I still had the applicator lying around. I extracted the injection needle from it (in future I would also use the needle holder) and after a wash in isopropyl I inserted it into the little hole on top of the sensor and pushed the filament into the groove on the needle. A good shove into your arm and bob's your uncle.

After about 20 min it started to provide readings. So it was operating, that is not to say that it worked.

As this was the first time I tried this I positioned the sensor so that I could see what I was doing. As you know you usually apply sensors from the side, but my head doesn't turn like that. So it turns out I positioned it poorly and it bled. I've had sensors that have bled before, and they never worked properly.

If you have 3 arms or someone to assist I'm sure it could be better positioned and be brought back to life.
 
The issue with washing in IPA is that the filament and/or the grooved needle, may be coated in anti inflammatory to reduce insertion trauma. Yet it is necessary to combat infection.
