What to do if measuring chain zero-point cannot be adjusted on Endress+Hauser Liquiline CM442R?
- A
  Amanda OrtizSep 8, 2025
  If the measuring chain zero-point on your Endress+Hauser Controller cannot be adjusted, test with a new sensor, as the reference system may be contaminated. Another possibility is a clogged junction, which can be resolved by cleaning or grinding the junction. Also, the asymmetric sensor voltage might be too high, in such case clean the junction or test with another sensor.

Why measuring chain slope cannot be adjusted on Endress+Hauser Liquiline CM442R?
- K
  Kimberly SanchezSep 12, 2025
  If the measuring chain slope on your Endress+Hauser Controller cannot be adjusted, is too low, or shows no slope, check the device directly, as the device input may be defective. If the device input is not defective, the sensor might be old and needs to be renewed. Another possibility is a hair-line crack in the glass membrane, which also requires renewing the sensor.

What causes incorrect current output signal from Endress+Hauser Liquiline CM442R?
- M
  Megan SkinnerSep 12, 2025
  If the current output signal from your Endress+Hauser Controller is incorrect, measure the load and reduce it to the permitted value if necessary, referring to the Technical data in the Operating Instructions under "Commissioning", as the total load in the current loop might be too high. Also, check the wiring and identify and eliminate the cause of interference, as EMC (interference coupling) may be the cause.
