Take Orbit Plot Measurement on Route 
 
Before  you  take  an  orbit  plot  measurement  on  route  you will  need  to 
enable  two  sensors.  To  do  this: 
1.  Press    Options. 
2.  Press    Sensor  Setup. 
3.  Enable  two  sensors  >  press  .   
 
NOTE: Ideally the sensors used to take the measurements should 
be displacement probes. This is because you are measuring the 
physical movement of the shaft. If required, you can also take the 
measurements with accelerometers (if no displacement probes are 
available). These measure the movement of the bearing housing, 
not the shaft. 
 
To  take  an  orbit  plot  measurement  on  route: 
1.  Press    or    Route. 
2.  Select  the  route  you  have  set  up  and  imported  from  Ascent. 
3.  Press    to  toggle  to  the  Axis/Point  Mode  to  Multi-Axis  (X  &  Y  for 
Orbit). 
4.  Press  the  buttons  on  the  left  of  the  Multi-Channel  On  Route  screen  to 
specify  you  X  and  Y  axes. 
5.  Press  the  buttons  on  the  right  of  the  Multi-Channel  On  Route  screen 
to  specify  all  the  other  the  axes  you  wish  to  record  >  Press  . 
6.  Select  the  axis  point  you  wish  to  take  a  recording  for  >  Press    to 
begin  sampling.   
7.  Press    again  once  the  plot  has  stabilized  —  A  single  waveform 
orbit  measurement  displays.   
 
NOTE: Filtering is NOT supported on your instrument. You can use 
Ascent for advanced analysis. 
 
8.  Press    Save  to  save  the  two  waveform  measurements  used  to 
generate  the  orbit  plot.  
 
NOTE: You must specify the vertical and horizontal channels in 
order to correctly view the orbit plot in Ascent.  
 
NOTE: The circle icon indicates the start position of the waveform. 
The triangle indicates the end.
