Thoroughly rinse the sensor
head with deionized water. Water the counter electrode in
deionized water for at least
10 minutes. Carefully shake off the drops
of water.
Fill a new membrane cap with
ELY/G electrolyte solution. Remove any air bubbles by
carefully tapping the mem-
brane cap. Additionally, you
can prevent air bubbles by
throwing the first filling away
and refilling the membrane
cap. Rinse the sensor head with
electrolyte solution.
Hold the sensor inclined and
screw on the membrane cap
fingertight using a paper tow-
el. Excess electrolyte solution
is forced out of the ventilation
area. Check the filling:
Inspect the face surface. No
air bubbles may be present
within the dashed circle. Air
bubbles outside this area do
not interfere.
