8.  Maintenance 

  Under  normal  conditions  (e.g.  clean  medium,  stable,  non-extreme  pH 

values) cleaning is recommended every 14 days with monthly calibration. 

  Electrodes are naturally consumed by loss of salt from the reference system, 

etc.  A  drift  in  measured  values  after  some  time  is  therefore  normal 
measuring behavior. 

  If the measured values drift, the electrode must be cleaned and calibrated! 

  Cleaning  and  calibrating  cycles  can  be  adjusted  depending  on  the 

application and process parameters.
