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.

(4) 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.
