Least count of an instrument means the minimum measurement which can be measured by that instrument correctly. For example various vernier callipers has the least count of 0.01cm. This means that if we measure the length of object below 0.01cm then it will not be correct and can have error.
This also means that its reading is correct upto 2 decimal place.
A yarn count meter is the instrument that directly measures the yarn count. It calculates the length and weight of the yarn to determine the count, which indicates the thickness or fineness of the yarn.
