Section 5: Moisture Measurement Mode
POINT
Make gases passed through a gas flow meter and exhausted from the atmosphere side of
a 3-way cock harmless and discharge them to the outside.
5-6. Measurement
5-6-1. Blank measurement
Blank operation is rarely done when a sample is taken with a syringe.
If samples can absorb external moisture in the injection like solid samples and the absorbed moisture
has an influence on the analytical data, the data should be corrected by the blank operation.
Select a calculation formula with "B" in titration parameters "Calc Form" and make the operation
same as sample measurement without sampling in "Blank Test".
The set number of times of the blank measurement is completed and the average of the results is
automatically inputted in "B". If abnormal values are found, input normal values manually. (Refer to
5-4-3. Sample parameters setting.)
If the blank value is known, set the number of times of the blank measurement in "Blank Test" to "0"
and input the blank value manually to "B".
(1) Wait until background is stable. By pressing [Titration] key, background is down.
(2) Wait until "Stable" is displayed.
(3) After pressing [Start/Stop] key, make blank measurement same as sample measurement. At this
time, background is saved.
(4) Titration starts.
(5) The result is printed.
When measurement reaches the end point at background +End Sense, a buzzer beeps and the result is
printed out.
(6) Subsequently, repeat (2) to (5) by the set times.
(7) The statistical calculation values are printed out and the average is automatically registered in "B".
