The replacement of the electrode head (4) and of the electrolyte is now com-
pleted. If you want to replace only the electrolyte, please proceed only the
steps 1, 2, 4 and 5. The handhold is illustrated as number (1) and the tempe-
rature sensor is illustrated as number (2) in the above mentioned description.
After any replacement of the elec
trode head (4) or of the electrolyte you
have to re- calibrate the measurement device.
Maintenance and cleaning
To clean (rinse) the electrode, only use distilled or de-ionised water and dab
dry with paper cloths. Do not use detergents that contain carbon, petrol,
alcohol or similar substances for cleaning purposes. This would corrode the
surface of the measuring instrument. Also, the vapours are detrimental to
health and are explosive. Never use sharp-edged tools, screwdrivers or met-
al brushes for cleaning.
Disposal
Old electronic devices are special waste and may not be dispo-
sed of in the household waste. When the device has become
unusable, dispose of it at the community collection point in
accordance with the statutory regulations in force.
