3.2 Connection plan
The electrical connection of the sensor on the
signal conditioning instrument is stated in the
operating instruction of the appropriate signal
conditioning instrument.
Note
The oscillator is independent of the electrode
and can be exchanged locally.
As the oscillators have certain tolerances
(approx. 5 %), it can be necessary to re-adjust
the signal conditioning instrument after having
exchanged the electronics.
