6.2 Calibration with reference pressure

The vessel is filled for either the lower range value or the upper range value for calibration.
Selecting the operating mode enables two vessel shapes to be chosen

•

vertical – "level linear" and

•

horizontal – "level cylindrical horizontal".

Calibration

menus

Entry

Fill the vessel to the lower range-value (empty)

Set the display to "0" by adopting an acting
bias pressure (position-dependent pressure).
