Unbalanced connection (standard)
when using a single-shielded connection cable
Slot Option/Connection option
IN 7 pH/ORP (redox) - Asymmetrical connection (standard)
IN 8 A separate temperature sensor can be connected to a temperature input or a universal input
IN 9 for temperature compensation.
IN 10 1 = glass/metal electrode (core) (A)
2 = not occupied
4 = bridge between 4 and 5
5 = bridge between 4 and 5
6 = reference electrode (inner shield) (B)
Balanced connection
(when using a double-shielded connection cable in conjunction with a separate earthing
pin in the liquid)
Slot Option/Connection option
IN 7 pH/ORP (redox) - balanced connection
IN 8 serves to reduce interference by scattering electromagnetic fields along the sensor cable.
IN 9 A separate temperature sensor can be connected to a temperature input or a universal input
IN 10 for temperature compensation.
1 = glass/metal electrode (core) (A)
2 = not occupied
4 = reference electrode (inner shield) (B)
5 = liquid potential (earthing pin) (C)
6 = shield (outer shielding) (D)
