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.

17.4.3 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.

5. If the end of the scan is larger than the beginning, decrease the Slow mag1 value. If the end

is too small, increase the value of Slow mag1.

6. Wait one complete frame with the new value before readjusting the Slow mag1 value.

7. Check the final result by capturing an image and checking it with the Offline > Modify >

Zoom window. The scanner is now ready for calibration of the X and Y parameters.
