Just FYI, if your TM was working well, and it has subsequently stopped working well, and you did not see an unusual light show with constant vibration, then your problem is unlikely to be resolved by a Temperature Range Adjustment (TA). Your problem is likely a contact issue.
Or oring sealing issues. Keep in mind there are 3 distinct types of orings used in the Tinymight: those on the cooling unit (if you use one), one to hold the stem, and one under the top plate that sits on top of the inner glass cylinder. The latter two are critical for optimal operation. Also check your battery and the contacts to insure they’re clean. Then the contact under the top plate as mentioned already recently. The recalibration should only be used as a last resort if one has tried all other things and your unit is running too cold or hot. I’ve never tried the recalibration (too chicken shit); don’t get much vapor below 5 with my year-old TM but it works well above that and I’ve accounted and adjusted for that. Life is good, what can I say...
Or a battery on its way out... can't skip past that as a possibility either!
I agree though. A once-working unit shouldn't be recalibrated as a "fix." These dont just fall out of calibration...a change in performance is an indicator of a problem somewhere else. Not the heat-output relative to the dials position.
