NOTE: Each time the calibration mode is entered all calibration
range indicators will be cleared, but only the calibration data for the
currently selected range will be replaced. The calibrations for the
other two ranges will be saved even though the indicators for those
ranges are no longer displayed. Calibration of all three ranges must
be performed during one power on period for all three calibration
range indicators to be displayed.
