How to fix invisible values on Endress+Hauser Micropilot FMR52 Radar display?
- V
  Veronica JonesAug 31, 2025
  If the values on your Endress+Hauser Radar display are invisible, here are some things to try: * The contrast setting may be too weak or too strong. Increase contrast by pressing the appropriate buttons simultaneously or decrease contrast by pressing the appropriate buttons simultaneously. * The plug of the display cable may not be connected correctly. Connect the plug correctly. * The display may be defective. Replace the display.

What to do if Endress+Hauser Radar displays a level when the tank is empty?
- P
  Patrick HoweAug 30, 2025
  If your Endress+Hauser Radar displays a level when the tank is empty, it is likely due to an interference echo. Carry out mapping over the entire measuring range when the tank is empty.

Why Endress+Hauser Micropilot FMR52 device measures incorrectly?
- Z
  Zachary FarleyAug 28, 2025
  If your Endress+Hauser Radar device is measuring incorrectly, it may be due to a parametrization error. Check and adjust the parameterization.

How to fix error message F941 or S941 "Echo lost" on Endress+Hauser Micropilot FMR52?
- C
  Crystal KhanAug 27, 2025
  The error message F941 or S941 "Echo lost" on your Endress+Hauser Radar indicates that the level echo is too weak or suppressed. To resolve this: * Check the Medium group parameter. If necessary, select a more detailed setting in the Medium property parameter. * Optimize the alignment of the antenna. If necessary, select a better installation position and/or larger antenna. * If the level echo is suppressed, delete the mapping and record it again.

What to do if Endress+Hauser Radar measured value jumps sporadically to a higher level?
- M
  Mr. Keith McdonaldAug 27, 2025
  If the measured value jumps sporadically to a higher level when the surface is not calm (e.g., during filling, emptying, or when an agitator is running) with your Endress+Hauser Radar, it's likely because the signal is weakened by the rough surface, making interference echoes stronger. Here are some steps to take: * Carry out tank mapping. * Select 'Process vessel with agitator' for the Tank type. * Increase the integration time. * Optimize the antenna orientation. * Select a better mounting position and/or larger antenna if necessary.

Why there is no change of measured value on filling / emptying with Endress+Hauser Micropilot FMR52?
- A
  Ann WellsAug 25, 2025
  If there's no change in the measured value during filling or emptying with your Endress+Hauser Radar, it's likely due to: * Interference echo from installations, nozzle, or build-up on the antenna. To resolve this: * Carry out tank mapping. * Clean the antenna if necessary. * Select a better mounting position if needed.

What to do if Endress+Hauser Radar measured value is incorrect?
- C
  Christopher PughAug 23, 2025
  If the measured value of your Endress+Hauser Radar is incorrect, here are a few things you can check: * If the measured distance matches the real distance, there may be a calibration error. Check and adjust the Empty calibration parameter, Full calibration parameter and linearization if necessary. * For measurements in bypasses or stilling well, ensure the correct tank type is selected and the tube diameter parameter is correct. Select 'Bypass / pipe' for the tank type and enter the correct diameter in the Tube diameter parameter. * Enter the correct value in the Level correction parameter. * If the measured distance does not match the real distance, there may be an interference echo. Carry out tank mapping.
