Not all printers provide sufficiently accurate sight
tapes without applying a customized scale factor.
To calibrate your printer, first Print either an
Inch Calibration Scale or a Metric Calibration Scale. If you select an
Inch Calibration Scale, the printed scale should have exactly 100 Marks
in a 4 inch Span. If you select Metric Calibration Scale, the printed
scale should have exactly 100 Marks in a 10 Centimeter Span.
Use an accurate ruler or pair of calipers, or
precision scale, to measure the number of marks in the Specified Span (4
inches or 10 centimeters). Record the number of marks, to the nearest
10th of a mark in the Specified Span. Enter this recorded value as
Calibration Scale Value and click Perform Calibration. Print out the
Calibration Scale again and verify that the Scale is the proper length.
