Setting up Custom Units Messages
User entered messages can be used to redefine units and to provide headers for serial data.
For example, suppose display scaling has been used to scale the tank volume readout by a
factor of 1000, that is, 10,000 cu ft is displayed as 10 cu ft. You could set up a custom
message of “K_CU_FT” and then select that message to be displayed for the volume units.
The system supports up to 8 custom (user defined) messages strings of up to 10 characters
each. Custom message menus are found in the “Special functions” menu described in the
previous section, as well as in the “Set up data format” submenu of the “Set up port …
data transmission” menu, see page 8-12. This menu option is also displayed when you
enable display scaling (see page 4-8).
