8. Wrap the plug with one or two turns of pipe tape..
9. Prepare a new membrane.
10. Hold the sensor at about a 45° angle with the cathode end pointing
up.
11. Add electrolyte solution through the fill hole until the liquid
overflows.
12. Tap the sensor near the threads to release trapped air bubbles.
13. Add more electrolyte solution if necessary.
14. Place the fill plug in the electrolyte port and begin screwing it in.
15. After several threads have engaged, rotate the sensor so that the
cathode is pointing up and continue tightening the fill plug.
Do not overtighten.
16. Place a new O-ring in the groove around the cathode post.
17. Cover the holes at the base of the cathode stem with several drops of
electrolyte solution.
18. Insert a small blunt probe, like a toothpick with the end cut off,
through the pressure equalizing port.

EQUIPMENT DAMAGE
Do not use a sharp probe. It will puncture the bladder and destroy
the sensor.
19. Gently press the probe against the bladder several times to force
liquid through the holes at the base of the cathode stem. Keep
pressing the bladder until no air bubbles can be seen leaving the
holes. Be sure the holes remain covered with electrolyte solution.
20. Place a drop of electrolyte solution on the cathode; then place the
membrane assembly over the cathode.
21. Screw the membrane retainer in place.
Quick Start Guide
a) Hold the membrane assembly with the cup formed by the
membrane and membrane holder pointing up.
b) Fill the cup with electrolyte solution.
c) Leave the membrane assembly filled with electrolyte solution
and set it aside.
