Description and Working Principle

4.1

Introduction

The UL1000 and UL1000 Fab basically is a helium leak detector for vacuum
applications, i.e. the part under test is evacuated while the test is performed. The
vacuum is achieved with a pumping system that is part of the UL1000 and UL1000
Fab. In addition the vacuum can be generated by pumps with are set up in parallel
to the leak detector.

Another operating mode of the UL1000 and UL1000 Fab is the Sniff mode which can
only be used when a sniffer line (See Chapter

Accessories and Options

) is

hooked up.

4.2

Components of the UL1000 and UL1000 Fab

The UL1000 and UL1000 Fab is a self-contained unit in a metal housing on wheels.
This housing contains the entire vacuum system and the according power supplies.
On top of the unit is the inlet port and the display.
