5.3 Zero point setting
In general, the zero point should only be checked and adjusted after the system has
been depressurised.
Mechanical and electrical zero point
If there is a deviation from the zero point (in depressurised condition), a zero point
correction can be carried out via the zero point setting (screw). The mechanical as well
as the electrical zero point can be adjusted simultaneously by turning the zero point
screw (at the front side of the instrument).
