6. The chamber will be evacuated to the set value and the measured values are continuously
displayed on the screen.
NOTE! If the currently measured “CO2” value increases when vacuum is applied,
then the package is most likely leaking and you should thus use another
package to perform the test.
During the measurement, check how much the package compresses the PackFix.
For larger, very flexible packages the optimal measurement is obtained when the PackFix
is compressed approx. 10-15 mm, which is approx. half of its total range of motion.
For smaller, less flexible packages the movement may be heavily reduced.
A smaller package will most likely need a higher setting of the Chamber vacuum (delta)
than a large package to properly compress the PackFix.
NOTE! Be aware that a higher “Chamber vacuum (delta)” setting does not
necessarily result in better measurements. This can cause PackFix to be
completely compressed, whereby the Delta P pressure becomes very unstable
from package to package and it will therefore not be possible to determine the
correct hole size.
7. If necessary use the and buttons to increase the chamber pressure by 10 or 50 mbar
respectively until the optimal PackFix compression is obtained, then press the button
to stop the test.
