7 The vessel is filled to the lower calibration
point. The pressure here is 0 mbar (0 psi), for
example.
Select the "Empty calib. (028)" parameter.
Menu path: Setup → Extended setup → Level →
Empty calib.
Enter the level value, here 0 m for example.
The pressure value present is assigned to the
lower level value by confirming the value.
8 The vessel is filled to the upper calibration
point. The pressure here is
300 mbar (4.35 psi), for example.
Select the "Full Calib. (031)" parameter.
Menu path: Setup → Extended setup → Level →
Full calib.
Enter the level value, here 3 m (9.8 ft) for
example. The pressure value present is
assigned to the upper level value by confirming
the value.
9 If calibration is performed with a medium
other than the process medium, enter the
density of the calibration medium in "Adjust
density (034)".
Menu path: Setup → Extended setup → Level →
Adjust density
10 Use the "Set LRV (166)" parameter to set the
level value for the lower current value (4 mA)
(0 m (0 ft)).
Menu path: Setup → Extended setup → Current
output → Set LRV
11 Use the "Set URV (167)" parameter to set the
level value for the upper current value (20 mA)
(3 m (9.8 ft)).
Menu path: Setup → Extended setup → Current
output → Set URV
12 If the process uses a medium other than that
on which the calibration was based, the new
density must be specified in the "Process
density (035)" parameter.
Menu path: Setup → Extended setup → Level →
Process density
13 Result:
The measuring range is configured for
0 to 3 m (0 to 9.8 ft).
For this level mode, the measured variables %, level, volume and mass are available,
see "Unit before lin. (025)"→ 86.
