The scale division value of a measuring instrument – is the meaning of the smallest division in the scale of the measuring instrument.
In order to determine the scale division value of a measuring instrument one needs to divide the difference between the closest points of the scale by the number of divisions among them.
Let us determine division value of the scale No. 1 of a track (gutter), Figure 1:
Figure 1
Figure 2
Measuring instrument limits are the highest and the lowest value of a physical quantity that may be measured with the help of this measuring instrument. Thus, the upper limit of measuring a track (gutter) in Figure No.1 equals 59 cm, lower limit equals 0 cm. The upper limit of measuring a track (gutter) in Figure No.2 equals 58 cm, lower limit equals 0 cm.
