Thanks for your feedback.

In theory it would be possible to tell the temperature if you have a know distance. The only problem seems to be that the clock of the ADC/DAC is often not running exactly at its nominal frequency. So, if you have a known distance, slide the temperature slider until the result matches (this works even after the measurement is complete). I've thought about this problem but decided against having an additional slider for the clock calibration, because I think that would have been to difficult to understand.
