Section 4: Measurement Preparation
CAUTION
When using grease containing much moisture, moisture in grease is sampled
successively even without contacting reagent. Much time is required for
dehydration.
(5) The rubber packing of a sample injection port is sometimes holed by repetitive measurement.
Before the packing is holed, open the sample injection port and change it to prevent the absorption
of moisture in the air.
(6) While anode solution and cathode solution are separated by a special ceramic board, both liquid
levels are same with time. (A special ceramic board mechanism is same as a filter.) When anode
solution level is upper than anode solution one, measurement values are improper. In this case,
extract cathode solution so that it is same as an anode solution liquid level or lower.
4-2. Titration cell preparation
(1) Anode solution (AQUAMICRON
Remove the sealing plug of a generator solution cell and pour about anode solution up to a cell
liquid level (about 100ml) with an attached funnel (large, bore diameter 55mmφ).
Remove the funnel and put back the plug.
(2) Cathode solution (AQUAMICRON
Remove the sealing plug of a cathode solution cell and pour about 5ml of cathode solution with an
attached funnel (small, bore diameter 35mmφ).
Remove the funnel and put back the plug.

(3) Put cotton balls into a drying tube, put silica gel, and put cotton balls again.
(4) Set a titration cell to the unit cell stand so that a sample injection plug is at the front.
(5) Connect a cathode solution cell connector to a stirrer G (blue). Connect a detection electrode
connector to a stirrer D (green).
1. Insert a connector into stirrer electrode connection part.
2. While pushing the connector end forward, turn it right to fix it.
* Fix it so that the connection part projection fits into the connector groove.
