d. If the reference electrode (7) is to be replaced, hold the electrolyte res-
ervoir vertical with the electrode uppermost. The electrode may now
be unscrewed, by holding it just below the wire stem, and replaced.
e. To replace the two membranes (6) in the reservoir housing a pair of
pointed tweezers (or similar) should be used. Insert the points into the
holes in the pvc body of the membrane and gently pull and turn until
the membrane is removed.
f. Fit new membrane using the same technique.
NOTE: The two half ring type platinum electrodes are arranged one above
the other in the top recess of the electrode housing (8), with the counter
electrode uppermost. To replace the working electrode it is necessary to first
remove the counter electrode.
g. Gently push the stem (blue spot) of the counter electrode until the
half ring can be grasped and the electrode removed from the housing.
h. If the working electrode (red spot) is to be replaced repeat step g with
the working electrode.
i. Carefully clean any grit or other deposits from the electrode recess
in the upper housing ensuring no moisture enters the electrode stem
bore.
j. Fit the replacement working electrode into thetop of the housing and
gently (to avoid disturbing the ‘O’ rings in the bore) push the electrode
down into position.
k. Repeat step j with the counter electrode.
l. Reassemble the reservoir to the electrode housing and, ensuring the
bottom cover (10) is on the cable, reconnect the signal wires as shown
in Figure 4.1:
