4 When doing so refill any spilled bridge electrolyte so that the inner
junctions are covered with bridge electrolyte.

Conditioning, calibration, measurement
We recommend using the cupric electrodes only for the end point
determination of titration procedures.
When operating the electrode ensure that
 the filling opening (1) for the bridge electrolyte is open
 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
Maximum depth of im-
mersion
1 Condition every ion sensitive electrode in standard solution before
using it.
