Filling the Electrolyte Solution
1.1 Take out the dissolved oxygen electrode and electrolyte solution
from the packaging. Unscrew the membrane cap from the bottom
of the electrode, rinse the inside and outside with distilled water
and blot dry.
1.2 Fill the membrane cap halfway with electrolyte solution.
1.3 Screw membrane cap back onto the electrode. Some electrolyte
solution will overflow during this process.
1.4 Check the electrode, ensure that no air bubbles are trapped in the
electrolyte solution and the membrane is not creased or damaged.
Polarizing the Electrode
2.1 Insert the 6-pin connector into the connector socket on meter,
ensure the connector is fully seated.
2.2 Switch on the meter and wait 10 minutes for the electrode to
polarize.
The dissolved oxygen electrode must be polarized before use.
