Calibration
Calibration is considered not to involve any adjustments. During
calibration, the accuracy of the barometer is verified using a suitable
pressure standard and due corrections are then given in the calibration
certificate together with a description of the international traceability
chain.
After having completed the calibration, the user should store the new
valid date of calibration in the memory of the barometer. This can be
done with the CALD command.
