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 -electrode should only be connected to the coaxial connector CH.2. Its banana
2
plugs should be inserted in the °C terminals.
A recorder can be connected to the red (+) and black (-) terminals. Use only labora-
tory recorders with a high input impedance!
A standard RS232 output terminal (DP9) is provided for interfacing the instru-
ment with a printer or computer. Data is sent in the ASCII code at a BAUD rate of
300...19200 bps (8 bit, no parity, 1 stopbit).
