4. On the display monitor, select Dual Trace. If the two scope traces do not overlap, Fast

6. Select Microscope > Calibrate > Scanner to open the Scanner Calibration box.
7. Select Fast mag1.
8. Use the left and right arrow keys to change the value until the two traces align.

9. When done, click OK to close the Scanner Calibration window.
10. Set Slow scan axis back to Enabled.
11. Select View > Image Mode.
Fine Adjustment
Initial adjustment is usually adequate; however, if more precision is desired, use the following fine
adjustment techniques to adjust Fast mag1.
1. Use the same procedure for adjusting Fast mag0.
2. As before, set the Zoom box for the beginning of the scan and then check the ending.
Because the scan is small, use a Zoom box up to one-half as large as the scan.
3. If the end of the scan is larger than the beginning, reduce the Fast mag1 value. If the end is
too small, increase the value of Fast mag1.
15.4.3 Adjust Slow Mag1
1. With the Scan size set to 150V, select Microscope > Calibrate > Scanner.
2. Select Slow mag1 and input the value from Fast mag1.
Note: For medium-sized scanners (C to F), further adjustments should not be
necessary. The Slow mag1 value is usually 100-120 percent of the Fast mag1
value.
3. If more precision is desired, adjust Slow mag1 using the same procedure for adjusting Slow
mag0.
4. Set the Zoom box for the beginning of the scan and then check against the ending. Because
the scan is small, use a Zoom box up to one-half as large as the scan.
