6.2.3 Calibration for density and concentration measurements
Hinweis!
Basic principles on the calibration for density and concentration measurements are described in
Section 6.5.1, page 70.
Background calibration
(for details see Section 6.5.2, page 72)
Step Function
1
2 Background calibration (*10)
3 Average pulse rate (*11)
4 Background calibration (*10)
5 Background pulse rate (*12)
continue by entering the calibration points
Calibration points
(One-point calibration, multiple-point calibration, recalibration)
(for details see Section 6.5.3, page 74)
Step Function
1
2 Calibration point (*1A)
3 Calibration (*15)
4 Average pulse rate (*11)
5 Calibration (*15)
6 Density calibration (*1B)
7 Density value (*1C)
8 Calibration point (*1D)
9 Absorption coefficient (*1E)
10 Reference pulse rate (*1F)
11 next point (*19)
Action / Remarks
Switch radiation off
Select "start" by O or S;
confirm by F
wait until value is stable;
then confirm by F
Select "stop/edit" by Oor S;
confirm by F
confirm value by F
Action / Remarks
• Switch on radiation
• Fill tube with medium of known density
or extract a sample of the medium during the calibration and deter-
mine its density in the lab (see step 4).
Enter number of the calibration point:
• for one-point calibration: "1"
• for multiple pint calibration: "1" - "9"
• for recalibration: "10"
Select "start" by O or S; confirm by F;
(extract a sample during this time and determine its density in the lab)
wait until value is stable;
then confirm by F
Select "stop/edit" by O or S;
confirm by F
Confirm value by F
Enter density of the medium (as determined in the lab).
select "used" by O or S;
confirm by F
this is a display parameter; confirm by F
this is a display parameter; confirm by F
• for one-point calibration: select "no";
calibration is thereby completed
• for multiple-point calibration: select "yes";
repeat stepts 1 - 10 for medium with a different density
• for recalibration: select "no";
recalibration is thereby completed
