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.
8 Enter the height value for the lower calibration
point via the "Empty height (030)" parameter,
here 0.5 m (1.6 ft) for example.
Menu path: Setup → Extended setup → Level →
Empty height
9 Enter the volume value for the upper
calibration point via the "Full calib. (031)"
parameter, here 1 000 l (264 gal) for example.
Menu path: Setup → Extended setup → Level →
Full calib.
10 Enter the height value for the upper calibration
point via the "Full height (033)" parameter,
here 4.5 m (15 ft) for example.
Menu path: Setup → Extended setup → Level →
Full height
11 Enter the density of medium via the "Adjust
density (034)" parameter, here "1 g/cm3" (1
SGU) for example.
Menu path: Setup → Extended setup → Level →
Adjust density
12 Set the volume value for the lower current
value (4 mA) via the "Set LRV (166)" parameter
(0 l).
Menu path: Setup → Extended setup → Current
output → Set LRV
13 Set the volume value for the upper current
value (20 mA) via the "Set URV (167)"
parameter 1 000 l (264 gal)).
Menu path: Setup → Extended setup → Current
output → Set URV
13 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" parameter.
Menu path: Setup → Extended setup → Current
output → Process density.
14 Result:
The measuring range is configured for
0 to 1 000 l (0 to 264 gal).
For this level mode, the measured variables %, level, volume and mass are available,
see "Unit before lin. (025)" →  86.
9.10.7 Calibration with partially filled vessel (wet calibration)
Example:
This example explains a wet calibration for cases in which it is not possible to empty the
vessel and then fill it to 100%.
