Transpector XPR 3+ Operating Manual
1.3.1  Returning Transpector XPR 3+ to INFICON
Do not return any component of Transpector XPR 3+ to INFICON before speaking 
with a Customer Support Representative and obtaining a Return Material 
Authorization (RMA) number. Transpector XPR 3+ will not be serviced without an 
RMA number.
Prior to being given an RMA number, a Declaration Of Contamination (DOC) form 
may need to be completed if the sensor has been exposed to process materials. 
DOC forms must be approved by INFICON before an RMA number is issued. 
INFICON may require that the sensor be sent to a designated decontamination 
facility, not to the factory.
1.4  Quick Start
Read this Operating Manual in full prior to operating Transpector XPR 3+. Then, 
follow the steps below to quickly start using Transpector XPR 3+.
1 Ensure that all supplied items have been received. See Chapter 13, 
Supplied Items.
2 Install the hardware. See section 1.16, Hardware Installation, on page 1-8.
3 Install the communication cable. See section 1.16.8, Installing Ethernet 
Communications, on page 1-23.
4 Install the software. Refer to the FabGuard Explorer Operating Manual for 
information on installing the software.
NOTE: Transpector XPR 3+ requires FabGuard version 17.04.00 or higher for 
operation.
1.5  Purpose of Transpector XPR 3+ Gas Analysis System
Transpector XPR 3+ Gas Analysis System is a quadrupole-based residual gas 
analyzer that operates at Physical Vapor Deposition (PVD) process pressures and 
has an Electron Multiplier that can operate at 20 mTorr operating pressures. The 
miniature quadrupole sensor analyzes gases by:
 ionizing some of the gas molecules
 separating the ions by their mass-to-charge ratio
 measuring the quantity of ions at each mass
The masses, unique for each substance, allow the identification of the gas 
molecules from which the ions were created. The magnitudes of these signals are 
used to determine the partial pressures (amounts) of the respective gases. 
Transpector XPR 3+ measures major components and impurities in a process with 
a 10 ppm detection limit.
