4.2 Function
The mass spectrometer module is a detection device for the test gases helium and
hydrogen. Integrated in test systems, the unit is used to detect gas being emitted
from a test object in order to indicate leaks.
The unit can be used both as a vacuum leak detector and a sniffer leak detector.
The MSB box outputs data on digital interfaces to the control unit CU1000, I/O
module IO1000 or bus module BM1000.
