Here we are going to learn to read the micrometer by figuring out the markings on the Thimble and the Sleeve. This is to prevent exerting too much pressure on the object measured. You can take a look and comment below, if you encounter any difficulties. Most micrometers include a design that allows a pin spanner to turn the barrel in relation to the frame, and this adjusts the zero line. See if you can calculate the measurement below Reading a micrometer gets easier with practice. Reading the Metric Micrometer To read the metric micrometer, first read the number of whole millimeters on the bottom row of the sleeve of the micrometer (Figure 3). I will not centre on the main scale. A screw micrometer should always be correctly zeroed using the wrench that is supplied with the micrometer prior to taking any measurements. Let’s take an example to understand this. A sleeve is attached to the head of the screw. Steps: You just have to add the first part and second part of the measurement to obtain the micrometer reading: $5.5 + 0.28 = 5.78$ mm. Take the reading.
