7. Dry off the ceramic frit on the base of the electrode with a lint-free
wipe. Squeeze the bottle for a few seconds. A small amount of filling
solution should bead up on the frit surface, indicating good filling
solution flow. If no moisture is visible, the electrode is clogged and
should be cleaned or replaced.
8. Invert the electrolyte bottle and snap it into the clip. Refer to Figure
II-10. Locate the discharge tube of the air pump on the fluidics panel.
The end of the tubing has a hollow push pin for pressurizing the
reference reservoir. Puncture the base of the bottle with the pin and
push the pin down until its PVC base abuts the bottle. Mark and date
the level of filling solution in the reservoir. The electrolyte solution will
begin to flow into the reference electrode.
Caution: Failure to pressurize the filling solution bottle will lead to
noisy and drifting output signals.
9. Plug the electrode cable marked "Reference" into the top of the
electrode, and tighten the screw cap. Be sure to push back the black
cap to verify a secure connection between the male and female pin
connection prior to tightening.
10. Tighten the screw cap connection to the cable.
Note: Do not twist the cable while tightening the connection. Twisting
may cause damage requiring premature replacement of the cable.
11. Insert the reference electrode into its port in the flow cell cap. Refer
Figure II-8 for the location.
