1.
Connect the EC sensor to the interface with a 4-core shielded cable with cores of 0.34 mm
2
(Ø
0.64 mm).
2. It may be possible to extend the cable. Extending the cable will, however, increase the measuring
error (see tables below).
In the case of an EC measurement via single cores, limit the length to 60 m.
3. Connect the shielding on the cable to the earth bar in the housing.
4. Adjust the cell factor with the potentiometer, see Calibrating the EC measurement (Compass)
(page 94).
