8.4.6 Zero-point calibration
This parameter specifies the time interval for the automatic zero-point calibration. The entry
is in min. Setting the parameter to 0 deactivates automatic zero-point calibration.
8.4.7 CS (creep suppression)
This parameter specifies the value for creep suppression as a percentage. If this value falls
short of the measured pressure value, the display is set to zero. Creep suppression only
works with volumetric flow, mass flow and flow rate (root-extracted measurement values).
8.4.8 Read factory settings
The factory settings are established in the instrument before delivery. With this menu item,
they can be reactivated if required.
8.4.9 Code?
You can use this menu item to specify an access code for the menu. If this code is <>0, the
access code will only be queried after the Menu key has been pressed. Only when the
correct code has been entered can you proceed to the menu. If the code = 0, this query will
not be made.
