5.5 Care
Membrane
Ensure not to damage the membrane and follow the storage
instructions in order to increase the service life of the elec-
trode. Creases or holes in the membrane are a sign that it
does not work properly any more.
If the membrane is soiled or if it shows signs of damage (this
might be indicated by incorrect measurement values), use a
spare cap with a membrane.
Cathode and anode
They must be polished with polishing cloths from time to time.
To do so, remove the cap so that the anode and cathode can
be accessed. Polish them with slight pressure and a clean
cleaning cloth in order to remove any deposits from the sur-
face. Rinse them with distilled water and then with alcohol,
shake the liquid off, and screw the cap back on loosely.
