8.3 Procedure for Evaluation of Conductivity Electrode
Try cleaning the electrode first (refer to Sect. 7.1). To check the electrode, check the electrode connections to the
terminal strip (refer to Figure 7). Make sure that the correct colors go to the correct terminals, and that the connections
are tight. Restore power and see if the conductivity is back to normal. If not, replace the electrode.
