CA-200 IMPORTANT SAFEGUARDS AND PRECAUTIONS
1
IMPORTANT SAFEGUARDS AND PRECAUTIONS
WARNING
Place Model CA-200 at the place where temperature is 5 to 40 degrees Celsius and
humidity is under 80%. The placement except these conditions causes troubles.
WARNING
Ground a power cable ground line or a ground terminal surely.
By touching the metal of Model CA-200 without grounding, you can get an electric
shock.
WARNING
As it thunders, do not connect a power cable. Danger of an electric shock by lightning
CAUTION
Do not place things infront of Model CA-200. When things are placed, the power switch
of the unit can’t be turned off emergently and accidents can be caused.
CAUTION
Do not connect many cords into outlets. Danger of a fire by outlet overheat
CAUTION
Place Model CA-200 at the place free from water, humidity, dust, and oily smoke.
Danger of a fire, breakage, and an electric shock
WARNING
Model CA-200 is not explosion prevention, so do not place flammable material near
Model CA-200. The placement except these conditions causes a fire and
an explosion.

IMPORTANT SAFEGUARDS AND PRECAUTIONS CA-200
2
WARNING
After stopping the unit or at the parts change, repair, and inspection, pull off the main
power plug necessarily to avoid an electrical shock.
WARNING
Pull out a power plug while holding it not to disconnect or short-circuit in a plug or a
cord.
WARNING
Put on protective goggles and gloves necessarily when using reagents. Without putting
on them, skin disorder and blindness can be caused.
CAUTION
Do not impact exposed glass not to break it. Fragments and scatter cause accidents.
WARNING
Never disassemble or remodel the unit. Contact our distributors if necessary.
WARNING
When a trouble happens, immediately notify the fact to the person in charge and take an
emergency measure. If the cause is unclear or the problemis not solved, never restart the
unit.

CA-200 Section 1: Measurement Principle
1-1
Section1:MeasurementPrinciple
ModelCA-200measuresmoisturebyapplyingKarlFischerreactiontocoulometrictitration.
In this coulometric titration, supply electrolytic solution mainly composed of iodide ions, sulfur
dioxide,and alcoholtoatitrationcell. Iodine fortitrationis internallygenerated byelectrolysis.
*KarlFischerreaction
Waterreactswithiodineand sulfurdioxide inbaseandalcohol.
H2O+I2+SO2+ROH+3Base2Base•HI+Base.....HSO4R (1)
*Coulometrictitration
Iodineis generatedfromiodine ionsbyelectrolysis intheanodesolutioncontainingiodine ions.
2I--2eI2··········································································································································(2)
When iodine generated by the reaction ofthe formula (2) is consumed according to the formula
(1), the consumption of iodine is detected by a detector electrode and iodine is generated again
fromananode by electrolysis according tothe formula (2).Thegenerated iodine is proportionalto
electric quantityby“Faraday’s law”.
Fromtheformula(1),theratioofreactionofH2OandI2is1:1.
Therefore, 1 mol (18g) of water corresponds to 2×96500 coulombs and 1mg of water
correspondsto10.72coulombs.
Basedonthe above principle,moisture content is calculated fromthe electricity forelectrolysis.

CA-200 Section 2: Installation and Assembly
2-5
2-1-2. Place for installation
(1) No large temperature changes, corrosive gas, dust, vapor, and direct sunlight
(2) Thetemperature should be 5 to 40 degrees Celsius and humidity should be under 80% without dew
drop.
(3) No electric and magnetic fields influence
POINT
Temperature change makes detection potential unstable and analysis accuracy
low. Direct sunlight causes liberation of iodine and analysis values are low.
2-1-3. Power supply
Connect a power cable apart from other units (large motors, dryers etc.) which generate noise.
In addition, connect it at the place where power change is within ±10%.
Use a 3P outlet with a ground or a 2P-3P adapter to ground firmly.
WARNING
If you touch the chassis metal part when an earth terminal is not grounded
completely, you get a shock.

2-2. Assembly
2-2-1. Titration cell
Remove each part of a titration cell and spread lightlycontacting parts with attached exclusive grease.
Put cotton balls and silica gel into a drying tube.
POINT
Necessarily use exclusive grease. Particularly when moisture adsorbs to the ceramic
septum of a cathode solution cell, much time is required until the widow condition
indication is stable. After leaving a cell in the air for a long time, dry it with a dryer and
assemble it.
(1) Put a titration cell to a stirrer stand so that a sample injection plug is at the front.
(2) Insert the BNC connector 1 of a detection electrode into the right connection jack (green). Insert
the BNC connector 2 of a cathode solution cell into the left connection jack (blue). Turn the cell
right to fix it.

2-2-3. Printer roll paper setting
(1) Take off a printer cover. Do not take off it forcibly.
(2) Cut the end of printer paper in a perpendicular direction to the feed direction. Put the paper from a
roll paper inlet so that the back of paper faces to this side.
(3) Raise a lever, pass paper so that printing side is downside, and lower the lever.
(4) Pass roll paper through the cover and set the cover.
Illustration 2-3. Printer roll paper setting
CAUTION
After paper setting, set a printer cover necessarily.
The cutter of a printer cover is sharp.
Take care not to get hurt at the setting.
