G See Table, Step 9.
H See Table, Step 10.
6 "Adjust density (034)" contains the factory setting
1.0, but this value can be changed if required. The
entered value pairs must correspond to this density.

7 Enter the volume value for the lower calibration
point via the "Empty calib. (028)" parameter, here 0
liters for example.
Menu path: Setup  Extended Setup  Level 
Empty calib. (028)
8 Enter the pressure value for the lower calibration
point via the "Empty pressure (029)" parameter, here
50 mbar (0.72 psi) for example.
Menu path: Setup  Extended Setup  Level 
Empty pressure (029)
9 Enter the volume value for the upper calibration
point via the "Full calib. (031)" parameter, here
1000 liters (264 gal) for example.
Menu path: Setup  Extended Setup  Level  Full
calib. (031)
10 Enter the pressure value for the upper calibration
point via the "Full pressure (032)" parameter, here
450 mbar (6.53 psi) for example.
Menu path: Setup  Extended Setup  Level  Full
pressure (032)
11 If calibration was performed with a medium other
than the process medium, specify the density of the
process medium in the "Process density (035)"
parameter.
Menu path: Setup  Extended Setup  Level 
Process density (035)
12 Result:
The measuring range is set for 0 to 1000 l (264 gal).
