Inputs
The pH/mV/Ion electrodes should be connected to the coaxial pH/mV connectors
CH.1, etc. If separate electrodes are used, connect the reference electrodes to the
REF. terminals. Connect the conductivity cell to the coaxial EC input. Automatic
temperature compensation and temperature measurements are possible by plug-
ging a Pt1000 thermocompensator into the °C terminals. Without compensator, the
manual temperature compensation is automatically switched on. C862 & C863: the
O
2
-electrode should only be connected to the coaxial connector CH.2. Its banana
plugs should be inserted in the °C terminals.
