10 "Adjust density" contains the factory setting 1.0 but
this value can be changed if required. The value
pairs subsequently entered must correspond to this
density.

11 Set the volume value for the lower current value (4
mA) via the "Set LRV" parameter.
Menu path: Setup  Extended setup  Current
output  Set LRV
12 Set the volume value for the upper current value
(20 mA) via the "Set URV" parameter.
Menu path: Setup  Extended setup  Current
output  Set URV
13 If calibration was performed with a medium other
than the process medium, specify the density of the
process medium in the "Process density" parameter.
Menu path: Setup  Extended setup  Level 
Process density
14 Result:
The measuring range is set for 0 to 1000 l (264 US
