Configuration
3.4.4 Review configuration data
Before operating the Rosemount 248 in an actual installation, review all of the factory-set
configuration data to be sure that it reflects the current application.
Review
When activating the Review function, scroll through the configuration data list to check each
process variable. If changes to the transmitter configuration data are necessary, refer to “Config-
uration” below.
3.4.5 Check output
Before performing other transmitter on-line operations, review the Rosemount 248 digital
output parameters to be sure that the transmitter is operating properly.
Process variables
The Process Variables menu displays continuously updated process variables, including sensor
temperature, percent of range, analog output, and terminal temperature. The primary variable
is the 4 –20 mA analog signal. The secondary variable is the transmitter terminal temperature.
3.4.6 Configuration
The Rosemount 248 must be configured for certain basic variables to be operational. In many
cases, these variables are pre-configured at the factory. Configuration may be required if the
transmitter is not configured, or if the configuration variables need revision.
Variable mapping
The Variable Mapping menu displays the sequence of the process variables. When using the
Rosemount 248 5 Variable Re-Map can be selected to change this configuration. When the Select
PV screen appears Snsr 1 must be selected. Either Sensor 1, Terminal Temperature, or not used can
be selected for the remaining variables. The primary variable is the 4–20 mA analog signal.
