3. Place the polystyrene sample provided with the instrument on the slide holder.
4. Rotate the 10x objective into the front objective position. (The software automatically
selects the video calibration for the 10x objective in the Acquisition window.)
5. Use the joystick on the microscope to position the polystyrene sample under the
objective, and the focus control to focus the image.
6. Choose
OK
in the software to start the wavelength accuracy test, which collects a
spectrum and compares measured peak locations to known values in wavenumbers.
When the test is completed, a message similar to the following is displayed:
7. Place the DXRxi silicon test sample provided with the instrument on the slide holder.
8. Locate and focus the sample:
• Use the 10x objective to locate and focus an area of the silicon test sample that
matches the image shown above
• Switch to the 50x objective
• Focus the image and center the crosshair on the decimal point in the “0.25” text on
the test sample
9. Click
Continue
in the software to start the image resolution test, which collects a map
(2 scans) of a specific region of the sample and compares measured line spacing values to
known values in micrometers.
When the test is completed, the PV results are displayed. Here is an example:
