    9 Commissioning Starting up The transmitter has been tested in the factory for fault-free functioning and is delivered ready for operation. The membrane (3) must not be touched or made dirty! In the course of normal operation, a grayish-white deposit may form on the anode of the sensor module.
  • Page 41 9 Commissioning Oxygen cells must be "run in" before calibration. This means that the cell is connected to the transmitter and then continuously operated in air that is saturated with water vapor until the reading no longer changes. Note: The vapor-saturated air is several centimeters above the water surface.
