The following parameters can be configured on the FMX21 using the 3 operating keys on
the front of the RIA15:
• Pressure engineering unit, level, temperature
• Zero adjustment (only for gauge pressure sensors)
• Empty and full pressure adjustment
• Empty and full level adjustment
• Reset to factory defaults

7.2 Operating concept
Operation with an operating menu is based on an operation concept with "user roles" .
•
Operator
Operators are responsible for the devices during normal "operation". This is usually
limited to the reading of process values. If the work with the devices goes beyond
reading, it concerns simple, application-specific functions that are used in operation.
Should an error occur, these users simply forward the information on the errors but do
not intervene themselves.
• Maintenance
Service engineers usually work with the devices in the phases following device
commissioning. They are primarily involved in maintenance and troubleshooting
activities for which simple settings have to be made on the device. Technicians work
with the devices over the entire life cycle of the product. Thus, commissioning and
advanced settings and configurations are some of the tasks they have to carry out.
• Expert
Experts work with the devices over the entire life cycle of the device, but, at times, have
high device requirements. Individual parameters/functions from the overall functionality
of the devices are required for this purpose time and again. In addition to technical,
process-oriented tasks, experts can also perform administrative tasks (e.g. user
administration). The "Expert" has access to the entire parameter set.
