Diagnosis
General incorrect measurements,
process errors or incorrect
parameterization (see also
section 5.3.2)
Measuring range overflow
Measuring electronics defective
Defective immersion check
Magnetic field current outside the
calibrated range
Fault in measuring function
(incorrect measuring frequency)
Self-test made with the result:
measuring tolerances too high in measuring tolerances too high in
relation to factory calibration
Device not in "Measure" status,
Simulation is switched on
Zero calibration (menu 6.6.2)
started and active
Measuring tube empty or only
partially filled
High percentage of gas
) Electrode DC voltage outside
permitted range itt d
) Current flow too high
Full scale value set too low
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.
Remedy
Menu 2.1 Call device status
Reduce flow quantity or increase full scale
value in menu 3.1.2
Measurement with reduced accuracy still
possible;
replace complete electronics
Deactivate immersion check (menu 2.3)
Recalibrate unit
Turn off mains synchronization (menu
3.1.7.2).
Electronics must be recalibrated, send in
device or complete electronics or repair device or complete electronics or repair
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
Device returns to measuring mode
automatically at the end of calibration
Fill measuring tube with medium, ensure it is
completely full
Clear gas occlusions or use gas trap
g Clean sensor electrodes
Reduce flow
Increase full scale value in menu 3.1.2
or reduce flow rate
