NOTE 
The hole placement pattern has been designed to prevent improper placement of 
the source.  
 
9  Reconnect the laser/source power harness to the proper 
connector as outlined in the removal process. Then connect the 
USB cable and the power harness (also outlined previously). Once 
all of the cables have been reconnected, replace the cover to its 
original position. Set the instrument on its side and tighten the 
four base plate retaining screws. Remember, these did not fully 
disengage and should already be in place. 
10  Replace your sampling accessory. Reconnect the power and USB 
external cords, and proceed as normal. You will want to check the 
energy values in the Diagnostics screen so that the value is 
correct. You may need to adjust the gain in order to achieve the 
appropriate amount of signal through the instrument (refer to the 
Diagnostics values section on Page 18 for proper energy values).
