Check that the sample flows correctly in
both normal operation and during a
calibration or thermal overload.
To simulate a calibration manually, open the
valve – see Section 6.2.1

Carefully remove the dissolved oxygen
sensor and check that the flowcell is empty.
If sample still flows, check that the
installation complies with Section 2.3.3.
