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.
