✱
Wait for the sensor module to run in (approx. 2hrs)
If the measurement is carried out in an area of low oxygen concentration,
the run-in time may be considerably longer, since the excess oxygen in the
electrolyte of the cell has to be used up first.
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. This deposit does
not
affect the proper functioning of the measuring cell.
Pressure fluctuations in the measured medium will affect the
output signal!
