xBT reporting 42.5 C

Totally normal for 42.5⁰C to kill you because the high heat denatures proteins and cell membranes causing widespread cellular damage, including the brain, kidneys, liver, and heart plus your blood will clot stopping blood flow to those vital organs…so yeah, totally normal to kill you.
In medical terms you would be fucked :face_with_crossed_out_eyes:

This might be of interest

Sorry, just fucking with you.

No you cant physically / firmware calibrate the xBT, though that would be nice.
They are not super accurate, but not normally that far out as yours.

That MIGHT be the reason for reading so high.
I haven’t personally heard of any reading that high.
I would expect the results to be within a couple of ⁰ of normal.

Where is your xBT located?

Is it consistently reading 42.5⁰C?

Have you tried reading at different clothing layer levels?
Will be hotter if you have been wearing an Artic style jacket vs a “wife beater”.

I would suggest you give it a few more days to heal and if you can, try another reader, or test your reader on another chip if possible.

Here some light reading whilst you heal

Hope that helped…
