13.2 Calibration standards from FISCHER
The density information of all calibration standards are computed
according to the values of the Heräus table, and are stated
accordingly on the certificates. Thus, the coating information of the
calibration standards have been determined according to the mass
per unit area method.
No data have been obtained using the cross-cut method.
By default, WinFTM uses the density values of the Heräus table.
The calibration lab of FISCHER has been accredited by the
Deutsche Akkreditierungsrat [German Accrediting Council] for the
measurement unit “mass per area unit”.
13.3 Setting the density in the Def.MA
You can manually set the density of an element in the Def.MA.
Please observe the notes of the previous sub-chapters.
Dialog window “Def.MA”. The current density setting for each
element is shown in the left window.
To open the dialog window “Def.MA”:
The menu command “Calibrate > Def.MA new > Thickness mode”
opens the dialog window “Def.MA” in the thickness mode.
The thickness mode is the most frequent mode selection.
If you wish to work in a different mode, select the respective mode
command to operate the dialog window “Def.MA” in the desired
mode.
