How do you read the scale?
Linear scale (1 mm interval)
Lower linear scale (0.5 mm interval)
Rotating scale (50
mm interval)
How do you read the scale on a Micrometer Screw Gauge?
Firstly, check for the zero error.
How do you read the scale on a Micrometer Screw Gauge?
Read the reading on the linear scale reading and add with coinciding circular scale multiply by least count.
Reading = Linear scale reading + (Coinciding circular scale x Least count) = 2.5 mm + (46 x 0.01)= (2.5 + 0.46) mm = 2.96 mm
