Configuration of Reference Reflector
For Safety Instrumented Systems (SIL) verify that the amplitude is within the following
recommended range:
Rosemount 5900 with Parabolic antenna: 600 to 1200 mV

Rosemount 5900 with Array antenna (Still-Pipe): 1000 to 3500 mV

Rosemount 5900 with simulated antenna: approximately 600 mV

Click the Save button to store the current calibration.
In case the product surface is too close to the Reference Reflector during the
calibration, a warning message will appear allowing you to choose whether to cancel or
to save the calibration data.
See Section 2: Installation
between Reference Reflector and product surface.
If calibration failed you may consider the following:
Check that the actual position of the reference reflector (RR) is within the search

window given by the calibration parameters RR Distance and Distance Tolerance.
Verify that the reference reflector is horizontal within the specifications for maximum

inclination (see "Tank Geometry - Parabolic Antenna" on page
Verify that there are no disturbing objects near the reference reflector that may

interfere.
