Stage reading measurement values is as follows:1. before you use the micro meter to see how much the Least Count is equal to the value based on the numbers written on A project, or it may be calculated (based on the resolution of a micrometer).2. must see that the edges of the circular scale is that much of the main scale position. Read in millimeters3. further to see whether the limit on how much a circular scale is the main axis of the grid corresponds to the scale, and then remove this number multiplied with the Least Count will be a fraction of millimeter.4. the sums derived from article 2 and 3 is the result of the measurement.
