Measure the inner and outer diameters 锛?/strong
It is usually necessary to use a ruler to measure the inner or outer diameter of an object, so do you know the correct measurement method? In fact, there is a small mechanism on the tape measure, and when used correctly, you can accurately measure the inner and outer diameters of the object.
This small mechanism is the three small circles of the head of the tape measure. It is flexible and can be moved by 1 mm. Therefore, according to this, we can accurately measure the inner and outer diameters of objects. When measuring the inner diameter of the object, hold the head of the tape measure close to the object so that the three small circles shrink inward. At this point, the measured dimension is the inner diameter of the object. If you straighten the three small circles on the tape measure when measuring the outer diameter of the object, then the dimensions you measure need to subtract 1 mm to be the correct outer diameter size of the object. low price Measure Tapes
