1.3.2 Technical Data PHOENIX L300i DRY
Physical data
To get down to the minimum detected leak rate range some conditions must be
fulfilled:
PHOENIX L300i has to run at least 20 minutes
Ambient conditions must be stable (temperature, no vibration/accelerations.)
The part under test has been evacuated long enough without using the zero func-
tion (background is no longer decreasing)
ZERO must be active
