Introduction and General Description 

 
Congratulations  on  your  purchase  of  the  AccuTrak  model  VPE-2000  ultrasonic 
inspection  system.    You  have  invested  in  the  most  sophisticated  and 
technologically  advanced  ultrasonic  test  instrument  available.    The  AccuTrak 
model  VPE-2000  is  an  excellent  tool  for  leak  detection,  but  it  also  does  much 
more.    This  instrument  will  accurately  test  steam  traps  and  valves  for  internal 
leaks!    It  will  allow  you  to  accurately  record  the  ultrasonic  sound  signatures  of 
bearings  and  other  moving  machinery  to  gauge  the  extent  of  wear,  and  predict 
failure BEFORE it occurs!   
 
We  at  Superior  Signal  have  dedicated  thousands  of  man  hours  developing  the 
AccuTrak  which  is  the  first  ultrasonic  detector  to  offer  digital  controls  and 
displays.    No  other  instrument,  even  those  costing  thousands  of  dollars,  can 
produce such accurate readings, and consistent results in repeatable tests.   
 
The internal signal processing is performed by a patented process with additional 
patents  pending.    This  circuitry  assures  the  reduction  of  "noise",  a  true 
translation  of  ultrasonic  frequencies,  and  the  most  precise  and  consistent 
readings available. 
 
Use  your  new  instrument  to  detect  pressurized  gas  leaks  of  compressed  air, 
refrigerant, steam, nitrogen, or even vacuum.  The touchprobe sensor allows you 
to  detect  the  slightest  flow  abnormality  in  pumps,  steam  traps  and  valves.  
Mechanical  wear  in  bearings  and  other  moving  machinery  can  also  be  quickly 
identified.    Overall  system  noise  can  be  recorded  and  compared  to  previous 
readings for an accurate record of increasing noise patterns. 
 
This  booklet  contains  information  necessary  to  use  and  interpret  sounds  with 
your  AccuTrak.    To  eliminate  any  future  frustration,  we  recommend  you  take  a 
few  minutes  to  read  this  manual  and  understand  the  operation  of  your  new 
instrument.    Again, congratulations.   We are sure you will be pleased with your 
choice.
