Proper Setup Steps:

  1. Unscrew the dissolved oxygen membrane cap from the electrode column.
  2. Rinse the internal cathode/anode with distilled water, then dry it.
  3. Add the provided solution to the cap and attach it to the column; don't worry if some spills during assembly.
  4. Secure the cap tightly, ensuring the cathode aligns with the membrane (no folds or tears).
  5. Rinse the electrode, place it in the sheath, and prepare for use. Note: After the first use or membrane replacement, polarization is necessary and takes about 15 minutes."
