CAUTION
Do not swallow the electrolyte. Avoid contact of the electrolyte with skin and eyes. Other-
wise wash with a lot of water. In case of eye infl ammation, contact a doctor.
IMPORTANT
• Do not touch or damage the membrane or electrodes.
• The electrolyte is sensitive to oxidation: always keep the electrolyte bottle closed after
use. Do not transfer the electrolyte into other containers.
• The electrolyte should not be stored for more than 1 year and should not yellow (use by
date, see label).
• As far as possible avoid forming air bubbles when pouring the electrolyte into the
membrane cap.
• The membrane cap must be used once only.
NOTE
• Store the electrolyte bottle upside down in order that the viscous electrolyte can be
poured easily and bubble free into the membrane cap.
• Smaller bubbles will not interfere, larger bubbles leave the electrolyte by rising to the
surface.
Pouring electrolyte
Open the electrolyte bottle and unscrew the nozzle.
Squeeze out excess air.
Fill the membrane cap with electrolyte, avoiding air bubbles as far as possible: Place the
electrolyte bottle completely onto the membrane cap. Slowly squeeze the electrolyte out of
the bottle in one steady stream, while continuously retracting the bottle. The cap is completely
full when the electrolyte reaches the lower edge of the thread.
Assembling
membrane
cap
Place the electrode shaft vertically onto the fi lled membrane cap.
Do not cover the vent hole below the rubber seal with your fi ngers.
Screw on the membrane cap by hand as far as possible. There should not be a visible gap
between the electrode shaft and membrane cap. When you screw on the cap, excess elec tro-
lyte will leak out through the hole below the rubber seal.
Wipe away any electrolyte with a soft paper tissue or similar.
Rinse the nozzle thoroughly with a clean, warm water jet so that no electrolyte remains on the
inside and outside of the nozzle.
