The use of the micrometer caliper is described in the lab manual. according to the micrometer caliper section, the smallest marked division on the micrometer caliper is

the smallest marked division on the micrometer caliper is 0.01 mm

Answering the question, the smallest marked division on the micrometer caliper is 0.1 mm

Micrometer caliper refers to an instrument that can be used to give a precise accurate measurement.

Micrometer caliper can be used to make a precise linear measurement, particularly thickness and diameter; it can as well be used in measuring the distance between two objects.

Further Explanation

The micrometer caliper is made up of a c-shaped frame and also has a jaw that is controlled by a screw.

The body parts of a micrometer caliper include:

C – Frame: this is the rigid part of the micrometer caliper and is meant to give support to other parts of the micrometer caliper such as the anvil and the spindle. Anvil: the anvil is the cylindrical part and it connected to the frame of the micrometer caliper. It is meant to support the measuring object. The object to be measured is positioned between the anvil and the spindle. Spindle: The spindle is attached to the sleeve, timber, and the ratchet. Its movement can be adjusted based on the size of the object to be measured.

Other body parts of a micrometer caliper include

Locknut Finely threaded screw Thimble Racket Knob

Therefore, the smallest graduation of the main scale of a micrometer caliper is 0.1 mm.
