14 After sharpening the electrode, apply a
small amount of grease (just enough to
prevent damage on the O-ring when
inserting the electrode as described in
step 15) on the lower part of the
electrode.
15 Using the electrode removal tool, insert
the electrode straight down until its
bottom contacts the electrode holder.
Electrode tip contamination may cause analytical value fluctuations.
Handle the electrode with care. Touching the tip with your hand may
cause contamination.
16 Clean the sample plate and dust cup.
Wipe off dirt on the sample plate using a clean cloth or something similar. Ethanol can
be used if necessary. Make sure that the sample plate is completely dry before
attaching it.
Wipe off dirt on the dust cup with a dry cloth or something similar.
