4.
Fill the electrode with new reference solution (#300), until it nears
the opening.
5.
Wash the tip of the electrode well with pure (de-ionized) water and
wipe it with filter paper or tissue paper.
6.
If the liquid on the inside of the electrode cap has dried, wash the
inside of the electrode cap with pure (de-ionized) water, and then,
after shaking out the water, fill the cap with enough pure water to
soak the sponge.
If the solution inside the protective cap for the electrode has dried up and the
electrode has not been used for an extended period of time, the response
speed of the electrode may be slower (and its sensitivity lower) than before.
