NOTE:
When calibrating an M2A-XL after changing the gas type, the M2A-XL will
not ask if you want to calibrate, or whether you want to perform a fresh air
adjustment, span adjustment or zero adjustment. Since a complete
calibration is required, the calibration sequence will proceed without asking
if you want to perform certain operations.
