Conventionally, the main scale of a caliper is formed integrally with the main scale, and the positional relationship between the measuring surface formed on the main scale and the measuring surface formed on the vernier's mounting has to be adjusted respectively. This could only be done with the measurement surfaces facing each other. Therefore, when the two measuring points of the object to be measured, such as the root diameter of a screw, are not on a plane perpendicular to the measuring surface of the caliper, accurate measurements cannot be made.

First, while keeping the distance between the movable door 3 and the vernier door 5 wider than the mouth 21 of the bottle 20, the mouth 21 is attached to the lower surface 15b of the positioning plate 15.
The tip surfaces 22 of the two are brought into contact with each other. Next, by adjusting the screw 14, the position of the positioning plate 15 is adjusted so that the measurement surface 5a of the vernier 2 comes to the trough 23a of the threaded part 23 formed in the mouth part 21, and the position of the positioning plate 15 is adjusted to the screw 11. Therefore, with the spindle 10a in the movable state, turn the knob 10b of the micrometer head 10 to adjust the measurement surface 3a of the movable jaw 3 to the trough 23a, and then tighten the screw 11 to prevent the spindle 10a from moving. fixed,
The measuring surface 3a of the movable jaw 3 and the measuring surface 5a of the vernier 2 sandwich the trough 23a, and the scale 1b of the main scale 1 is
