  • Page 31: Dry Calibration

    Dry calibration is a theoretical calibration which can be carried out even though the Cerabar S is not mounted and with a vessel filled to any height. The "empty" calibration point is usually at the mounting point of the measuring cell. If measurement starts at another level, then this must be included in the calculation.

The height is automatically determined by the "gauging" Cerabar S by the hydrostatic pressure, the appropriate volume is entered. In addition V3H6 offers the functions: Activating table A linearisation table is valid only if it is specifically activated.
