The center display line shows the measured sensor output in millivolts.
As calibration procedes, a progress indicator appears in the lower display line. When
the measured sensor output stabilizes, the lower display line shows

The display then changes for 2 seconds to show the temperature-corrected buffer
value in the upper display line, then advances automatically to the next frame.
