Touchprobe applications... 

 

Use  the  touchprobe  to  detect  internally  generated  ultrasound.    These 
applications include...  steam traps, valves, and bearings.  

 

1.  Insert  the  metal  touchprobe  into  its  port  (B.)  on  the  nose  of  the  VPE-2000

.  

The  probe  should  be  snug  so  it  can  not  rattle,  however,  do  not  overtighten.

  

Depress  the  mode  select  button  (F.)  until  the  display  reads 

“PrbH,  PrbL  or 

PrbS”.  This stands for Probe hi

gh  /  low  ultrasonic  range,  and  Probe  Sonic. 

Press the 

” and “

” 

to activate the touchprobe selection. 

2.  Making  a  firm  contact,  touch  the  tip  of  the  probe  to  the  item  being  tested.  

Apply  just  enough  pressure  to  make  a  good  contact.    You  will  hear  a  clear 
translation of the internally generated ultrasonic sound. 

3.  Listen for fluid leaks in valves, continuous flow or non-cycling in steam traps, 

and knocking or scraping in bearings.   

4.  The  VPE-2000  always  defaults  back  to  Sensitivity  as  the  active  mode, 

therefore if your readings are off the scale simply press the 

 to reduce the 

reading  to  within  the  range  of  the  instrument.    The  A.N.D.  will  display  the 
active  sensor  and  current  sensitivity  setting  before  it  begins  to  make  the 
adjustments. 

5. 

To adjust the volume, press the mode button once.  The A.N.D. reads “VOL”.  

Then  use  the 

”  and  “

” 

buttons  to  make  the  adjustment.    The 

alphanumeric display (A.N.D.) will read “V000”.  Volume, as with all numerical 

values, has a range of 0 to 255. 

6.  When testing bearings or machinery vibration, record your sensitivity setting, 

and  use  the  reading  on  the  A.N.D.  as  a  baseline  for  future  readings.    Now 
you  can  compare  the  wear  patterns  to  future  tests,  and  other  similar 
equipment. 

7.  For  more  specific  information  on  using  the  touchprobe,  refer  to  page  13  of 

this manual. 

 

WARNING

:   

To  insure  a  good  contact,  and  accurate 

readings  the  touchprobe  is  sharp!    Be  careful  not  to  injure 
yourself or others!
