Important Notes and Hints
The tuning procedure runs automatically to a large extent without any problems. However, several errors
can occur. That’s why it is strongly recommended to observe the complete calibration process.
If a status error message occurs or the calibration procedure is not finished properly, this can have the
following reasons:
No optimal positioning of the calibration standard.
One end of blue and black line jumps a bit forward and backward because software recognizes
sometimes the outer line of the grating and sometimes not.
•
Stop the calibration procedure.
•
Check the focus of the calibration sample.
•
Check if the yellow horizontal line crosses the scale pattern of the calibration standard properly.
•
(If necessary) Shift the calibration standard by half a scale unit (No scale tick but a gap has to be
situated directly on the edge of the image).
•
Restart the calibration procedure.
No optimal setting of Detector gain and Amplifier Offset.
The forward-backward-difference shows a lot of peaks and changes significantly from image to
image.
•
Stop the calibration procedure.
•
Calibrate speed 12 (unidirectional) electrically.
•
Optimize gain & offset: Ticks of the grid have to have intensity values of 250 ... 255 (just before red
color in
Range Indicator
palette). Minimum intensity values have to be between 1 ... 5 (no blue parts
occur in the image by applying
Range Indicator
palette).
•
Restart the optical calibration procedure.
Sliders of Scan Corr. X and Scan Corr. Y in the Mode sheet of the Scan Control window were
not set to zero.
Calibration process does not converge.
•
Stop the calibration procedure.
•
Set both values to zero.
•
Restart the calibration procedure.
