The program will automatically search for associated result fields. The condition is, however, that
all
files must use the same ID as a file name
(e.g. 45901.wgs and 45901.dgs). The operator can still
overwrite information displayed in the contact angle fields, in which case the Sample ID window will
be erased. As soon as the input fields (one, two or three) have been completed, the program will
automatically calculate the SFE results. When manual data is typed into the input fields, it is necessary
to click on ‘Calculate’ to determine the SFE values. The SFE results are displayed in the Results
Window at the bottom of the screen.
The
Save
button will store a copy of the report in the default directory (e.g. \fibro\pg) with the
extension
sfe
(e.g. 45901.sfe). When the file has been stored the ‘Save’ button becomes inactive until a
new result is calculated.
For corona treated polymers water can be used as the single liquid to determine SFE in
accordance with ASTM D5946-0. The SFE result is then presented directly in the Static window
when the ASTM parameter in the Options Menu is set to “ON”(see Section 9.11).
For determination of SFE using other liquids please see Section 9.14 of this User’s Manual.
Please note SFE calculations can only be done from static contact angle test results!

This screen displays a window with the current configuration settings, which can be used for support
and diagnostics. Some of the program functions can also be modified from this screen.
