4.2.2 Filling Bead Case with Electrode Polishing Glass
Beads
Contamination adhering to the gold alloy surface of the gold alloy rotating electrode results in
measured value error. To prevent such error owing to contamination, the gold alloy surface is
continuously polished with glass beads during operation.
Fill the bead case in the measuring tank with glass beads which are delivered by placing in the
accessory box.

Glass Beads Filling Procedure
(1) Remove the electrode mechanism block by loosening two fixing screws.
(2) Put the glass beads into the bead case.
Feed the glass beads up to the lowest slit position (approx. 4 cm above the bottom) of the
bead case.
(3) Restore the electrode mechanism block.
Note: The upper surface of the glass beads with the indicator electrode placed in the bead case is to be located 1 cm higher than the
lowest slit position.
