14 5975/5977 Series MSD Operation Manual
1 Introduction
Vacuum gauge
The MSD may be equipped (or ordered) with an ion vacuum gauge. The
OpenLAB CDS Acquisition software can be used to read the pressure (high
vacuum) in the vacuum manifold. Operation of the gauge controller is
described in this manual.
