7. During the measurement, observe the Package pressure (ΔP) value.
NOTE! A Package pressure (ΔP) value of 25 mbar or higher is a good indicator
that the device can measure leaks in the package. Values between 15 and 25
mbar will work on some types of packages, whereas values below 15 mbar can
be critical.
On packages with a CO
2
content below 25%, a ΔP of 25 mbar can be to low.
On packages with a very high content of CO
2
leaks might be detected at ΔP
values below 15 mbar.
If a package's content of CO
2
as well as the achievable ΔP makes it difficult to
obtain uniform measurement results, you may also consider trying with a
longer or shorter test time than the default set test time.
See "Test Time *" on page 59 for details.
If necessary use the and buttons to increase the chamber pressure by 10 or 50 mbar
respectively until you have obtained an appropriate ΔP value as described above, then
press the
button to stop the test.
NOTE! The selected vacuum level needs to be high enough to ensure an
appropriate “ΔP” value, but not so high that it damages the package.
8. Now write down the final Chamber vacuum (delta) value and the obtained Package
pressure (
ΔP) value.
9. Tap the icon to exit and return to the product settings.
10. Now set Vacuum Delta to the value as obtained above.
