11. If the calibration is performed with a medium other than the process medium, enter
the density of the calibration medium in the "Adjust density" parameter. Here 1 g/cm³
(1 SGU), for example.
 Menu path: Setup → Extended setup → Level → Adjust density
The process density can only be changed if automatic density correction is switched
off (see Step 4).
12. Set the volume value for the lower current value (4 mA) via the "Set LRV" 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" parameter
(1 000 l (264 gal)).
 Menu path: Setup → Extended setup → Current output → Set URV
14. 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 → Level → Process density.
The process density can only be changed if automatic density correction is switched
off (see Step 4).
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 "Output unit" →  96.
9.9.7 Calibration with partially filled vessel (wet calibration)
Example:
This example describes a wet calibration for situations in which it is not possible to empty
the vessel and then fill it to 100 %.
During this wet calibration, a level of 20 % is used as the calibration point for "Empty" and a
level of "25 %" is used as the calibration point for "Full".
The calibration is then extended to 0 to 100 % and the lower range value (LRV)/upper
range value (URV) are adapted accordingly.
Prerequisite:
• The default value in level mode for the calibration mode is "Wet".
• This value can be configured: Menu path: Setup → Extended setup → Level → Calibration
