Measuring mode "User"

Description
The "User" measuring mode is the simplest of the measuring modes that you can select with
the measuring mode selector. Only one further device variable, "User", is activated in this
measuring mode in addition to the four standard device variables. The variables "Level",
"Volume", "Mass", "Volumetric flow" and "Mass flow rate" are marked as inactive and are
given the status CONSTANT.
In the "User" measuring mode, you have an option to define a customized unit for output
scaling. This customized unit is, e.g. a specific quantity of liquid. This quantity of liquid
depends on the input process pressure.
Example: Fill the beverages in cans having a capacity of 0.33 l. You can now define a
customized unit "Can" that is exactly equal to 0.33 l. The quantity of "cans" depends on the
input process pressure.
Note
Permissible input values
All alphabetic a...z, A...Z and numeric 0...9 inputs are allowed for the customized unit. The
following characters are also allowed:
° " $ / < > * , _ + - = @
