2. With this calibration point, the density of the product is entered in the "Density value
of calibration point" field.
This establishes the reference between the determined pulse rate and the density
of the product.
TIP: it is recommended to take a sample of the medium during the integration
and determine its density subsequently (e.g. in the laboratory).
3. Activate the density calibration point
A0042203
At least two of the four available density calibration points must be activated at the
end. Three or four points can also be used, however. This increases the accuracy for
determining the absorption coefficient µ and empty pulse rate I
0.
If the calibration is
to be ended after recording 2 density points, you can click the "Next" button to skip
density points 3 and 4 without calibrating or activating them. The Gammapilot
FMG50 then ignores these two density points.
The "Calibration date of density point" field provides the user with information on the time
the specific calibration value was recorded.
A0042209
In the event of the subsequent calibration of a new density calibration point, a free
calibration point can be used and activated or an old measuring point can be
overwritten.
One-point calibration
The user can choose from two different ways to perform the one-point density calibration.
The choice is made when the user is asked to "Use the Applicator settings"
A0042210
"Use the Applicator settings" = No
A density point is calibrated and the preset absorption coefficient of 7.7 mm
2
/g is used to
calculate the density values. Here, it is also possible to enter an absorption coefficient if
this application-specific value is known for the measurement.
"Use the Applicator settings" = Yes
