Calibration method
The method by which the measuring system must be calibrated depends on the
respective measuring arrangement.
Inverted Curve
If the check box ″Inverted curve″ (Fig. 80, item1) is acti-
vated, the monotony criterion of the validation
changes is strictly ascending.
Linear
Two points (usually 0% and 100%) are required. The
container is emptied and filled to determine the count
rate at 0% or 100% level.
To increase the accuracy of measurement and take
non-linearities of the characteristic curve into account,
a larger number of measurement points can be used.
1 Point Exp.
The absorption coefficient, the measuring path and the
product density must be known. The second calibration
point is thereby calculated.
2 Point Exp.
Exactly two calibration points must be entered.
