Figure 15.7a Calibration Horizontal Reference
Verify that the microscope’s measured distance agrees with the known horizontal distance. If there
is significant disagreement between the two, fine tuning is required; go to Step 3 below. If the
displayed distance agrees with the known distance, skip to Section 15.7.3.
3. Based upon the results in Step 2, perform the following calculation:
Divide the known distance by the distance displayed next to the line drawn in Step 2. Record this
value.
4. Select the Realtime > Microscope > Calibrate > Scanner option. The Scanner
Calibration dialog box displays (see Figure 15.7b).
Draw a horizontal line.
