What to do if current output 01 or 02 is not calibrated on Endress+Hauser Prosonic S FMU90?
If the Endress+Hauser Measuring Instruments indicate that current output 01 or 02 is not calibrated, it is recommended to call Endress+Hauser service.
What to do if there is a faulty calibration for level 01 or 02 on Endress+Hauser Measuring Instruments?
If your Endress+Hauser Measuring Instruments report a 'faulty calibration for level 01 or 02', adjust the calibration settings in the "level" menu.
What to do if electronics are defective in Endress+Hauser Prosonic S FMU90 Measuring Instruments?
If your Endress+Hauser Measuring Instruments display an electronics defect, try switching the instrument off and on. If the error persists, it is recommended to call Endress+Hauser service.
What to do if I get a download error on Endress+Hauser Prosonic S FMU90 Measuring Instruments?
If you encounter a download error with your Endress+Hauser Measuring Instruments, repeat the download.
What does it mean if the safety distance is reached for sensor 01 or 02 on Endress+Hauser Prosonic S FMU90?
The error indicates a danger of overfilling. The error disappears if the level is out of the safety distance again. Possibly, the function "acknowledge alarm" must be used (s. "safety settings" menu)
Why doesn't the measured value change when filling or emptying a vessel with Endress+Hauser Prosonic S FMU90?
If the measured value on your Endress+Hauser Measuring Instruments does not change when filling or emptying a vessel, perform a tank map (interference echo suppression).
How to fix faulty calibration for level 01 or 02 on Endress+Hauser Measuring Instruments?
To resolve a faulty calibration for level 01 or 02 on your Endress+Hauser Measuring Instruments, adjust the calibration in the "level" menu.
What to do if Endress+Hauser Measuring Instruments show an incorrect measured value?
If your Endress+Hauser Measuring Instruments display an incorrect measured value, check the "actual distance" and correct it if necessary.
How to troubleshoot echo loss (Error E@@641) on Endress+Hauser Prosonic S FMU90?
To troubleshoot echo loss (Error E@@641) on your Endress+Hauser Measuring Instruments, check all settings in the "application parameters" parameter set.
Why does the measured value jump sporadically to higher levels with an uneven surface on Endress+Hauser Prosonic S FMU90?
If the measured value jumps sporadically to higher levels with an uneven surface on your Endress+Hauser Measuring Instruments, perform a tank map (interference echo suppression).
