Interval (Min); Volume (L); Channel - LEYBOLD GRAPHIX ONE Instruction Manual

 Principally, a leak test in the overpressure range would also be possible with the pressure
rise method. The leak rate would then be negative, since the leakage is leaving the test
volume. Because of the principal temperature dependence of the test pressure large
measuring errors can thereby arise, which require an experienced operator, so that all in
all the pressure rise method in the vacuum range is more recommendable.
7.8.1

Interval (min)

Through this parameter you define the duration of the leak test.
The value is entered in minutes. You may set up the interval for leak test within the range
from 1 – 1999 minutes. The default setting is 10 minutes.
7.8.2

Volume (l)

Enter the volume of the test vessel.
The value is entered in liter. You may set up the volume within the range from 0.1 – 100000.0
liter. The default setting is 1.0 liter.
7.8.3

Channel

Through this parameter you define which channel shall be used for the leak test.
