(10°) and set that position as 10° in software.
If a value other than zero is
entered as the offset value, the angle shifted the amount of correction value is
recognized as the DATUM angle (10°).

Select Control - Initialize Individual Axis - Theta/2-Theta, and click the
Execute button.
This procedure is to prevent the direct beam from entering the detector by
moving the current angle.
Next, execute
D/teX Ultra Center Correction
. To execute with direct
beam, move on to
12
. To execute with a sample, move on to
13
. It is
recommended to execute by the direct beam.

Set DS=1.25°, SS=Absorber (Cu plate 0.3 mm x 1 or 2 plates), and
RS=OPEN. Enter 0° as Theta/2-theta position (deg).

The correction value is registered in the MiniFlex Guidance
automatically after the measurement is completed.

Install the beam stop. If the retracting screw is mounted on the
variable knife edge, remove it. Fill the 0.5-mm glass sample plate with
angle reference material (NIST, SRM-640d) and set it on the sample
holder.

Set DS=1.25° and SS=RS=OPEN.
When the incident and receiving Soller slits are 5°, enter 47.25°in the
Theta/2-theta position (deg)
box. When the incident and receiving
Soller slits are 2.5°, enter 47.26°in the
Theta/2-theta position (deg)
box.
