4.3.2 Measuring cable and sensor connection
To connect pH electrodes with MemoSens functionality to the transmitter, you require the
terminated data transmission cable CYK10 with 2x2 cores, twisted pair, screen and PVC
jacket.

1 Coupling (to connect to the sensor) with integrated electronics
For further information on the cable, please refer to the "Accessories" section.
To plug the cable coupling onto the sensor plug-in head, proceed as follows:

Fig. 23: Handling of sensor plug-in head and cable coupling
1. Rotate the lower part of the coupling in
such a way that the two pairs of keys
(pos. 1, 2) are located above each other.
2. Plug the coupling onto the plug-in head
so that the keys engage in the slots of the
plug-in head (pos. 3).
3. Turn the lower part of the coupling
(pos. 4) clockwise as far as possible
(approx. 60°). Doing so locks the coupling
and prevents the connection from
opening inadvertently.
Open the connection in the reverse sequence
of operations.
