8 If calibration is performed with a medium other than
the process medium, enter the density of the
calibration medium in the "Adjust density (034)"
parameter, here 1 g/cm
3
(1 SGU) for example.

9 The pressure for the lower calibration point is
present at the device, here 0.5 m covered / 49 mbar
(0.71 psi) for example.
Enter the volume value for the lower calibration
point via the "Empty calib. (028)" parameter, here 0
liters for example. (The pressure currently measured
is displayed as the height, here 0.5 m (1.6 ft) for
example.)

10 The pressure for the upper calibration point is
present at the device, here 4.5 m covered / 441 mbar
(6.4 psi) for example.
Enter the volume value for the upper calibration
point via the "Full calib. (031)" parameter, here
"1000 liters" (264 gal) for example. The pressure
currently measured is displayed as the height, here
"4.5 m" (14.8 ft) for example.

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).
