title: Four measurement methods of calipers
description: ノギスには4つの測定方法があります。【内側測定】内径を測る際には、内側測定用ジョウ（クチバシ）を測定部分に差し込みます。【外側測定】外径を測る際には、外側測定用ジョウで測定物を挟み込みます。【深さ測定】穴や溝の深さを測定する際には、デプスバーを底に当てます。【段差測定】段差測定面を測定部分に差し込みます。

## Four measurement methods of calipers

With calipers, you can measure various lengths;

however, the measurement method differs depending on the location you want to measure.

In this article, we will introduce four measurement methods of calipers.

 

【Outside measurement】

When measuring the outer diameter of an object, use the outer measurement jaws to clamp the object,

ensuring that the outer measurement surface is in close contact with the object for measurement.

【Inside measurement】

When measuring the inner diameter of holes, pipes, or similar objects, insert the inner measurement jaws (beak) into the measuring area,

ensuring that the inner measurement surface is in close contact with the object for measurement.

【Depth measurement】

When measuring the depth of holes or grooves, ensure that the depth reference surface is in close contact with the measuring area,

then insert the depth bar and place it against the bottom for measurement.

Using the depth bar for depth measurement can be unstable.

Therefore, if the measuring surface is sufficiently wide, consider performing a step measurement

 

【Step measurement】

　Insert the step measurement surface into the measuring area and perform the measurement.

If the corners of the step are rounded, perform depth measurement using the depth bar.

Calipers that do not align the main scale and the slider's edge when closed cannot perform step measurement.

We also offer digital calipers that are capable of performing step measurements.
