Note.
When connecting non-metal conductivity cells or metal conductivity cells that are isolated from earth (ground), e.g.
mounted in plastic pipework, link Terminal B14 (and Terminal B6 if dual input analyzer) to the earth (ground) stud on the
analyzer case - see Fig. 6.8.
When connecting earthed (grounded) metal conductivity cells, ensure that the cell earth (ground) and the analyzer earth
(ground) stud are at the same potential.
