Setting Up the Print Form Using PDM Products with a variable or fixed block size
82 FISCHERSCOPE
®
X-RAY
All variables and parameters that otherwise refer to single readings
refer, in this case, to the mean values of the individual blocks
(except for histogram and normal probability chart, which continue
to refer to single readings).
This changes the meaning of the characteristic statistical quantities
(see appendix “Statistical formulas of measurement technology for
the FISCHERSCOPE X-RAY” in the operator’s manual).
Example: Final evaluation
28 measurements are stored in a product in three blocks.
For 28 measurements of a product, which have been measured
using
variable block size, the result for the variable "@NB1"
(number of measurements) in the final print form is 28, because all
single readings of this product have been used to determine the
final result.
If, on the other hand, the measurements have been taken using
fixed block size, the result for the variable "@NB1" is 3, because
the block mean values of the three blocks of this product have been
used to determine the final result.
Attributes of the sample / dependence on the measurement
mode
The number of quantities to be measured (attributes) in a
measurement application that can be computed, displayed and
evaluated depends on the measurement mode.
Example: Triple coating measurement
Measured and displayed are:
- Thicknesses of the top coating and the two intermediate coatings,
or
- for alloy coating measurements, the coating thickness and the
composition.
To display the statistical quantities, such as mean value or standard
deviation of these measurement quantities in the print form,
different variables are required.
For example, if after double-clicking the variable “@MW1”, the
command button [Measurement quantity 2] is actuated in the dialog
