1 Remove the storage vessel.
2 Fill the bridge electrolyte ELY/BR/503 into the filling opening.
3 Shortly press the shaft of the combination electrode against the con-
nection head to wet the ground junction with bridge electrolyte.
4 When doing so refill any spilled bridge electrolyte so that the inner
junctions are covered with bridge electrolyte.

 the inner junctions (3) are covered with bridge electrolyte
 no air bubbles are in the bridge electrolyte
 the depth of immersion is within the optimum range:
Minimum depth of im-
mersion
