TRANSMAG 2 with MAG 911/E
Operating Instructions, 03/2021, A5E00102775-AC
Diagnosis
Measuring range overflow
Measuring electronics defective
Defective immersion check
Magnetic field current outside the cali‐
brated range
Fault in measuring function (incorrect
measuring frequency)
Self-test made with the result: measur‐
ing tolerances too high in relation to fac‐
tory calibration
Device not in "Measure" status, Simula‐
tion 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
Current flow too high
Full scale value set too low
Remedy
Reduce flow quantity or increase upper range val‐
ue in menu 3.1.2
Measurement with reduced accuracy still possi‐
ble; 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
(See chapter Return procedures)
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
Clean sensor electrodes
Reduce flow
Increase upper range value in menu 3.1.2 or re‐
duce flow rate
