8.5 Maintenance of the pH or ORP measurement
The metallic surface of the ORP electrode must be cleaned regularly. pH and reference electrodes change
with time, so their characteristics have to be determined regularly by means of calibration.
NOTE The instrument checks the sensor’s characteristic parameters after each calibration and displays an error
message if the sensor has to be replaced. See chapter „Error messages“.
8.6 Disposal
For disposal please notice that the device contains electrolyte capacitors which have to be disposed
separately.
