148 FISCHERSCOPE ® X-RAY
Calibration, Base Correction and Reference Measurement
Procedure
1. In the WinFTM main window select Calibrate > Calibration Standard Set… .
An empty window will
appear, if the measuring
application has not yet been
calibrated.
If the measuring application
has already been cali-
brated, check the values in
the window. If the values
are plausible, click
OK and
skip the steps 2 to 7
2. Enter a name for the calibra-
tion standard set in the field
Label (e.g., Cr/Ni/Cu Ser.
No. 13917).
3. Click Input/Overwrite .
The window
Standard No. 1 appears.
4. Enter the name of the
standard (e. g., AAMGW).
5. Enter the values of the cali-
bration standard. Click the
field three times in order to
enter a value.
The fields have the following meaning:

Value Nominal value of the calibration standard (in the example coat-
ing thickness d1 (Zn) in μm coating thickness d2 (Ni) in μm, Cu
concentration in %)

u +/- If an uncertainty for the reference value is stated on the certificate
for the calibration standard, enter this value here. If you do not
enter a value, then the following values will be used: for coating
thicknesses, 1% of the coating thickness; for concentrations, 1%
absolute.

Type With multi-coating systems, it may be the case that existing interim
coatings act as base material of a calibration standard or that
coatings are not present. This setting is made here.
