    Mycom S CPM 153 7 Maintenance Maintenance CPM 153 does not contain wear parts and is maintenance free. Measuring point maintenance comprises: • cleaning the assembly and electrode • inspecting cables and connections, • calibration (see page 83). Warning! Danger to persons. If you have to remove the electrode for servicing or calibration work, pay attention to the hazards caused by pressure, temperature and contamination.
  • Page 90 7 Maintenance Mycom S CPM 153 7.1.3 Calibration Calibration is necessary: • after electrode replacement • after downtimes (Caution: a pH glass electrode may not be stored in a dry environ- ment.) • At reasonable intervals, dependent on the process. The required interval can range between several times a day to once every three months.
  • Page 91 Removing diaphragm blockages: Blocked reference system for reference electrode diaphragms can be mechanically cleaned (does not apply to IsFET pH sensor, teflon diaphragms or open ring electro- des): • Use a small key file. • Only file in one direction.
