A primary calibration is carried out when operating the instrument
for the first time and is used as a reference for the following
calibrations. Generally, it should be carried out only after a
consequent modification.
It allows to fix the zero and slope reference.
All the results of the further manual or automatic calibrations will
be compared to the zero and slope references set by this
calibration.
A more important shift will allow to detect an error calibration
which will be signified by an error message.
This calibration can be realized only in the manual way.
