Why Seli STS-03 display no or erroneous measured value?
- R

  If your Seli Measuring Instruments display no or erroneous measured values, there could be several reasons. First, check the voltage at the sensor, ensuring the electrical connection is correct. Second, the measuring windows might be coated; clean them. If they frequently get dirty, consider using an STS04 with SAW8XX quick-change fitting. Finally, an erroneous calibration could be the cause. In this case, reset the calibration to factory settings in the calibration menu.

  If the output current doesn't match the measured value in your Seli Measuring Instruments, it could be due to a couple of reasons. The current output might be parameterized incorrectly, so check and, if needed, change the parameterization of the current output. Also, an incorrect electrical connection can cause this issue, so verify and correct the electrical connection.

Why Seli Measuring Instruments show strongly fluctuating measured value?
- I
  ihansenAug 16, 2025
  If you observe strongly fluctuating measured values on your Seli Measuring Instruments, consider these possible causes. One reason might be air bubbles in the system; in this case, dampen display and output current. Another cause could be that the sensor is not completely submerged in the process fluid; if so, change the installation location.

What to do if switching output does not switch properly on Seli STS-03?
- M
  Mark ParksAug 22, 2025
  If the switching output of your Seli Measuring Instruments isn't switching properly, there are a couple of potential causes. First, the switching output might be parameterized incorrectly; check and, if necessary, change the parameterization of the switching output. Second, the electrical connection could be incorrect; verify and correct the electrical connection.

What does error message on the display of Seli STS-03 Measuring Instruments mean?
- D
  Daniel JonesAug 27, 2025
  If your Seli Measuring Instruments display an error message, here's what it could mean: * **Err0 Factory comparison failed:** Repair with the manufacturer. * **Err1 User parameters incorrect:** Use the function in order to reset the user parameters. * **Err2 Temperature measurement failed:** Repair with the manufacturer. * **Err3 Measuring range spreading failed:** Check the parameters 'MRB' and 'MRE'. Ensure maximum spreading is 4:1. * **Err4 ADC error:** Repair with the manufacturer. * **Err4 Temperature overriding (100°C) Factory setting:** Lower the temperature of the medium below 100 ° C again.
