10. Remove the electrolyte container from the electrode mount. To do
this, unscrew the knurled nut in the electrode mount.
11. Remove the electrolyte container out the electrode mount from the top.
12. Remove the drain plug from the electrolyte container.
13. Turn the electrolyte container upside down and drain the electrolytes
by lightly shaking it.
Replacing Reference Electrode
14. If necessary, replace the reference electrode. The reference electrode
can be unscrewed from the electrolyte container. Lightly wet the O-ring
before installinga new reference electrode.
Replacing Porous Membranes
15. The porous membranes, which form the contact between the reference
electrodes and sample water, cannot be cleaned. If the water quality
is very good, the porous membranes can remain installed for up to
three years; they should be replaced thereafter (no exceptions). If the
sample water quality is poor, the porous membranes may be soiled.
This influences the measuring accuracy.
16. Remove both porous membranes from the electrolyte container using
a suitable tool (e.g. tweezers).
17. Push new porous membranes into the electrolyte container. Lightly
wet the O-rings.
18. Insert the electrolyte container back into the electrode mount. Lightly
wet the O-ring here as well.
19. Fill the container with fresh electrolyte (approx. 3 cm above the water
level or narrowing of the electrolyte container).
20. Insert the drain plug into the electrolyte container.
21. Insert the electrode mount back into the cell body using the electrolyte
container.
NOTE: The cell body’s dowl pin must be locked into place in the appro-
priate hole in the electrode mount.
22. Screw the upper knurled nut back onto the electrolyte container.
23. Reconnect the signal cable acc. to colour.
