Diagnosis Remedy
F Flashing ”F” in the top
right hand corner of the
display General incorrect measurements,
process errors or incorrect
parameterization (see also
section 5.3.2) Menu 2.1 Call device status
F Device status (menu 2.1 )
”Measurement module
failure”
Measuring range overflow Reduce flow quantity or increase full scale
value in menu
3.1.2
F Device status (menu 2.1 )
”Measurement module
Measuring electronics defective Measurement with reduced accuracy still
possible;
replace complete electronics
Defective immersion check Deactivate immersion check (menu 2.3 )
Magnetic field current outside the
calibrated range Recalibrate unit
Fault in measuring function
(incorrect measuring frequency) Turn off mains synchronization (menu
3.1.7.2 ).
F Device status (menu 2.1 )
”Calibration failure
Self-test made with the result:
measuring tolerances too high in Electronics must be recalibrated, send in
device or complete electronics or repair
”Calibration failure
measuring module” measuring tolerances too high in
relation to factory calibration device or complete electronics or repair
F Device status (menu 2.1 )
”Simulation is running”
Device not in ”Measure” status,
Simulation is switched on End simulation (exit the menu ”Simulation”
2.5.2 , 2.5.3 or 2.5. 4 or select ”End” in menu
2.5.1.
Alternatively: Restart the device

6.4 Cleaning
Use only mild cleaning agent to clean the transmitter. “Aggressive”
agents such as hydrochloric acid (even diluted), alcohol or abrasive
media may not be used.
