Membrane Cap Replacement:
1. Do not touch the membrane as skin oils will interfere
with the oxygen permeability rate of the membrane.
Replace the cap carefully.
2. It is recommended that the probe remain attached to
the meter during this replacement process.
3. Unscrew the cap firmly and carefully from the probe.
4. Rinse the old electrolyte solution from the Cathode
and Anode.
5. Use the supplied Polishing Strips to clean, polish,
shine, and/or remove scratches from the cathode. Be
sure to moisten the cloth before polishing the cathode.
Do not over-polish the sensitive gold cathode.
6. Set the new replacement membrane cap on a flat
surface. Leave the cap in this position during the
replacement process.
7. Fill the membrane cap with the electrolyte solution up
to the bottom of the threads on the inside of the cap.
8. Tap the membrane cap to release and prevent air
bubble in electrolyte solution.
9. Keeping the cap in a fixed position on a flat surface,
carefully insert the probe into the new cap by first
dipping and removing the probe several times from the
cap. With each dip, push the probe progressively
deeper into the bonded cap. Finally, screw the probe
slowly onto the cap until fully tightened. The dipping
and removal technique minimizes the introduction of
air bubbles into the electrolyte solution. Air bubbles in
the electrolyte can affect measurements.
10. It is normal that excess electrolyte solution will leak out
