Fig.5-41 Horizontal scale range is 5.60mm Fig.5-42 Vertical scale range is 4.20mm

EX5: Calibrate the scale for Contacted in high mag.

Use the “calibrator” as a measurement base, flatly put the machine on the

observing object, adjust the focus to find the clearest image. See Fig.5-43

and Fig.5-44 the result from measurement. Horizontal and vertical scale

range is 1.40mm and 1.05mm. Using a calibrator is more easily and

accurately to get scale range.

(7) Factors cause the inaccurate on the measurement

There are few factors could cause the inaccurate on the measured figures.

 The used ruler is not exactly accurate, for example, a metal ruler is not

accurate than a calibrator.

 Because of the discrepancy, it is unable to know the accurate horizontal and

vertical scale range, too.

 The resolution is not the same with the Windows size.

Why is the resolution not the same with the Windows size? For example the present resolution

(original video image of output size) is 640*480 the measurement of the Windows's for general is

400*300 sizes. When the original video image size is 640*480 by reducing to 400*300, the
