Setting the zero point (calibration) [CAL]
For adjustment of the zero point, the vacuum circuit of the system must be
vented (to the atmosphere).
Press the <MENU> key.
If the menu is locked, enter the appropriate PIN.
Press the <UP> or <DOWN> key several times until [CAL] appears in
the display.
Press the <ENTER> key to confirm the selection.
The display then blinks briefly and returns automatically to the display mode.
A zero-point offset is possible only within the range 3% of the full-scale value.
In other words, the zero point can be shifted by up to 30 mbar from the original
zero point.
If you exceed the permissible range of 3%, the error code E3 appears in the
display.
