Measurement Status Measurement Status messages that may appear on the Integral Display, on
the 275/375 Handheld Communicator, or in the Rosemount Radar Master
(RRM) program are shown in Table 7-5:
Table 7-5. Measurement status.
Message Description Action
Full tank
The level measurement is in Full Tank
state. The transmitter waits for the surface
echo to be detected at the top of the tank.
The transmitter leaves the Full Tank state
when the product surface gets below the
Full Tank Detection Area, see “Full Tank
Handling” on page C-5 and “Full Tank
Handling” on page C-10.
Empty tank
The level measurement is in Empty Tank
state. The transmitter waits for the surface
echo to be detected at the bottom of the
tank.
The transmitter leaves the Empty Tank
state when the product surface gets above
the Empty Tank Detection Area, see
“Empty Tank Handling” on page C-4 and
“Empty Tank Handling” on page C-7.
Reference pulse invalid
An error in the reference pulse in the last
sampled tank signal.
Check Warning messages. If MicroWave
Module (MWM) Warning is active, this
might indicate a transmitter error. Contact
Emerson Process Management Service
Department.
Sweep linearization warning The sweep is not correctly linearized.
Check Warning messages. If MWM
Warning is active, this might indicate a
transmitter error. Contact Emerson
Process Management Service
Department.
Tank signal clip warning The last Tank Signal was clipped.
Check Warning Messages. If MWM
Warning is active, this might indicate a
transmitter error. Contact Emerson
Process Management Service
Department.
No surface echo
The Surface Echo Pulse cannot be
detected.
Check if the configuration can be changed
so that the surface echo can be tracked in
this current region.
Predicted level
The presented level is predicted. The
surface echo could not be detected.
See No surface echo above.
Sampling failed The sampling of the last tank signal failed. Check Warning Messages.
Invalid volume value The given volume value is invalid. Check Volume Status for details.
Simulation Mode
The simulation mode is active. The
presented measurement values are
simulated.
No action needed.
Advanced Simulation Mode
The advanced simulation mode is active.
The given measurements are simulated.
To turn off the Advanced Simulation mode,
set Holding Register 3600=0 (see “Analog
Output Calibration” on page 7-14).
Tracking Extra Echo
The transmitter is in the empty tank state
tracking an extra echo.
See “Extra Echo” on page C-4 and
page C-9.
Bottom Projection The bottom projection function is active.
See “Tank Bottom Projection” on
page C-4.
