零点
主尺は上側が0.1.2.…と1mmごと、下側は0.5mmずれて目盛り線が入っている。
副尺は0.01mmごとに目盛り線が刻まれており、一回転で0.5mm。
目盛り線が合わない場合の千分台は、だいたいしか分からないので目測で読む。
主尺を読むと4.5mmとなる。
5mmの線が見えているが副尺の目盛りを考えると5mmではない
次に副尺を読むと0.49mm、目盛りの間をも読むと0.488mmとなり、主尺と副尺を合計して4.988mmとなる。

Zero point.
On the main scale, graduation lines are marked in increments of 1mm as 0, 1, 2, … in the upper side and ones in the lower side are marked with displacement of 0.5mm.
On the vernier scale, graduation lines are marked in increments of 0.01mm and it moves 0.5mm with one rotation.
A value of parts per thousand, which is seen when scale marks do not match others, should be read by eye as the only approximate value can be obtain.
The scale reading of the main scale is 4.5mm.
The 5mm line can be seen but considering the tick mark of the vernier scale it is not 5mm.
Next, the scale reading of the vernier scale is 0.49mm and if reading the interval of the graduations, it is 0.488mm. The total of the main scale value and the vernier scale value is 4.988mm.
Check bumps etc.
Confirm an expiration date label.

The scale mark of the upper side of the main scale is per 1mm, 0.1.2., and so on, while the under side is out of 5mm.
The vernier scale have scale marks every 0.01mm, and is 0.5mm at one round.
Measure by the eyes the fourth decimal place when the scale line does not match, because it's not clear.
The main scale shows 4.5mm.
The 5mm line is in the eyes, but it's not 5mm in consideration with the scale mark of the vernier scale.
Then the vernier scale shows 0.49mm, and then 0.488mm if we measure the gap between the marks, so the length is totally 4.988mm, adding up the main scale and the vernier.
Check for the curve and so on
