Decommissioning
Operations to be performed every time the instrument is put out of service for long periods:
• Switch off the instrument
• Close the inlet and outlet valves outside the instrument
• Check that there is water in the electrode holder so that the electrode is always wet. Otherwise loosen
the ring nut and put the electrodes in a container with some water or with some KCL solution.
