high, Shaft seal replacement, Sensor is missing.
Displays all actual error messages:
EM is too high, Concentration is too high, Calibration test., Replace the wiper., Service is due,

Correction factor for the measured value.
Possible settings: 0.80–1.20
Default: Factor = 1
Adjustable from –250 to +250 mE for zero point correction
Default: Offset = 0
Perform a zero point calibration
Perform a single point calibration
Select Output mode or Calibration interval
Output mode: Select the behavior of the outputs during calibration for zero point setting (Hold,
Active, Transfer, Choice). Hold maintains the last reading prior to going into the menu. Active
transmits the current level readings, corrected with previous calibration data until new data is
entered. Set Transfer transmits the value designated during the system setup
