Correct the zero point

In the event of undesirable deviations in a depressurised state (atmos-
pheric pressure), the zero point can be corrected manually.
■
The zero point correction can only be carried out for deviations up
to a maximum of 5% of the full scale value.

Always carry out the zero point correction in a depressurised state
to avoid incorrect measurements.
