FISCHERSCOPE ® X-RAY 19
Components
2.5.8 Absorber
The absorber consists of a thin foil made of cobalt or nickel, which is located between the specimen
to be measured and the detector.
The absorber eliminates undesirable components of the fluorescence spectrum. Using an absorber
can make it easier to evaluate the secondary x-radiation in the computer under some
circumstances.
The absorber can be controlled using the software, if the WinFTM extension SUPER is installed.
To enable or disable the absorber
1. In the WinFTM main window select Product > Modify... .
The window Modify product appears.
2. Select the tab Application .
3. Click Def.MA (local) .
The window Definition of measuring conditions... appears.
4. In the right upper area of the window enable or disable the absorber and click OK .
2.5.9 Key Switch for the X-Ray Energy
With the key switch you turn the high voltage supply of the x-ray tube on and off. Without high
voltage supply to the x-ray tube, x-radiation cannot be generated. Consequently, measurements are
not possible.
Measurements can only be performed when the key is inserted and turned to the right.
For your safety, you should turn off the x-radiation when you are finished using the instrument, then
pull the key and store it in a safe place. This prevents unauthorized use of the instrument and gen-
eration of x-radiation.
Control LEDs of the high voltage supply:

The yellow LED HV ON on the control panel of the instrument lights immediately upon turning
on the high voltage.

The red control LED X-RAY ON on the control panel of the instrument lights when the high
voltage is reached its full level. This may take a few seconds after turning the key switch.
