} Fill the measuring cell with approx. 100ml of fresh electrolyte solution (approx up to
the manual dosing port). For creation of the electrolyte solution, see (→ "Preparing
the measuring cell" 83).
} Carefully place the stirring rod back in the measuring cell.
} Reinsert the electrodes in the measuring cell. Connect the electrodes to the "Genera-
tion" and "Indication" connections.
} Place the measuring cell in the holder on the magnetic stirrer.
} Insert the gas inlet tube into the measuring cell. Connect the gas inlet tube with the
HX absorber via hose 72.
} Activate the magnetic stirrer (set to stage 3 approx.).
NOTICE!The magnetic stirring rod can damage the electrodes if the rotation fre-
quency is set too high. Operate the rotary switch with care.
} Wait for approx. 5min for the new electrolyte to collect in the salt bridge of the gen-
erator electrodes and for the measuring cell to establish equilibrium. Before starting
any measurement, the end point routine must be performed.
ü The detection module is ready for operation again.
14.14 Maintenance of the TOC detector
NOTICE
Risk of gas leaks
System tightness for the gas path from the inlet of the basic module to the outlet of the
detection module is not regulated automatically.
¡ Always check the system tightness after performing maintenance on the detection
module (→ "System tightness for TOC methods"
144).
