Transpector XPR 3+ Operating Manual
Defines the action that occurs when the Flex Trip Level is reached. Flex Trip
Level is typically used in FabGuard to turn the Emission and Electron Multiplier
back on after safe vacuum conditions are achieved.
NOTE: Flex Trip Action can turn the Emission or Electron Multiplier, or both, back
on during a process that cycles between base vacuum and higher
pressures.
Flex Trip Mode
Figure 5-11 Flex trip mode
Defines the Flex Trip mode.
Flex Trip Level
Figure 5-12 Flex trip level
Defines the level of the Flex Trip. If INFICON Pirani, MxG, or BxG option is chosen
as the Signal Type, the value entered here will be in units of Torr or millibar
depending upon the units selected in Signal Type.
5.5 Using Transpector XPR 3+
Once the sensor has been conditioned, by baking it out and then keeping it under
vacuum, the emission can be turned on.
5.5.1 Leak Detection
Using FabGuard Explorer, there is no recipe required for operating in Leak Mode.
Select the Leak Mode button to default to sampling Helium (mass 4) over time.
When leak checking a vacuum system that has a pressure of 1x10
-5
Torr or lower,
the High Pressure Electron Multiplier should be used. The HPEM voltage that is
necessary is based on the level of the leak that you are searching for. Adjust the
HPEM voltage so that the Helium (Mass 4) signal can be observed, but do not
exceed an intensity of 1E-7 amps. Refer to the FabGuard Explorer Operating
Manual for complete information on Leak Detection Mode.
