Physical Data
Hinweis
To get down to the minimum detected leak rate range some conditions
must be fulfilled:
•
UL1000 and UL1000 Fab has fully warmed up
•
Ambient conditions must be stable (temperature, no vibration/accelerations.)
•
The part under test has been evacuated long enough (background is no longer
decreasing)
•
ZERO must be active
