6.4.2 Electrolyte Change
1. Unscrew the measuring chamber from the shaft.
2. Hold the measuring chamber at an angle and fill approximately 7 to 8 ml
electrolyte, up to approximately 1 cm under the top edge.
3. Tap the filled chamber several times on a flat surface, so that adherent air bubbles
can detach and rinse.
4. Screw the electrode shaft into the measuring chamber vertically from above,
ensuring that all inside air is displaced.
5. As soon as the inserted O-ring begins to seal, tighten slowly to the stop.
NOTE:
Refill the electrode with every 6-12 months, or when unstable values displayed.
Depending on the chlorine content on site, this period can be reduced or
expended.
NOTE:
If the chlorine electrode continues to display unstable values, a new membrane
cap must be used.
WARNING:
Do not swallow the electrolyte. Avoid contact of the electrolyte with skin or eyes. In
case of accidental contact, wash with a lot of cold water!
In case of eye inflammation contact a doctor immediately. Wear safety glasses and
gloves when working with the electrolyte solution.
CAUTION:
Do not touch or damage the electrolyte. 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 one year
and should be clear (not yellow) in appearance (use by date, see label). Avoid
forming air bubbles when pouring the electrolyte into the measuring chamber.
6.4.3 Membrane Cap Change
1. Unscrew the measuring chamber from the shaft.
2. Unscrew the front screw cap holding the membrane.
3. Remove the old membrane and replace with a new membrane.
4. Refill the measuring chamber with electrolyte.
NOTE:
Change the membrane cap once a year, or when unstable values displayed.
NOTE:
If the chlorine electrode continues to display unstable values, a check /
reconditioning by the manufacturer has to be done.
