To prepare a reference electrode for installation:
1. Remove the packing material from the reference electrode.
2. Rinse the outer surface of the electrode with distilled water.
3. Wipe the electrode dry.
4. Remove the internal electrode from its protective cover.
5. Remove the O-ring from the inner pin without damaging pin's surface.
6. Place a new large O-ring in place of the one just removed.
7. Insert the internal electrode into the chamber of the electrode.
8. Install the internal electrode pin loosely (do not tighten).
9. Remove the cap from the reference filling solution bag.
10. Tightly screw the reference electrode tube fitting into the filling solution bag tube fitting.
11. Squeeze the bag to partly fill the electrode chamber if needed.
The filling solution should be above the connection from the filling bag to the inner
chamber. See Figure 17. Reference electrode
12. Tighten the electrode cap first by hand, then with the tightening tool.
The tightening tool is located at the opposite end of the pin's original protective cover.
13. Rinse the electrode briefly under tap water and dry carefully with tissue paper.
14. Place small O-ring to its place. See
To prepare an electrode for an installation:
1. Open the foil bag.
