Высокая точность resolation 0 001 мм вне микрометра цифровой набор

The outer diameter micrometer is an outer dimension measuring instrument that uses the principle of the spiral pair to read the distance separating the two sides of the frame. The outer diameter micrometer is mainly used to measure various outer dimensions.

1. Clean the measuring surface and correct the zero position before use. 0-25mm direct alignment zero: 25mm or more with the school team for the quasi-zero position;

2. Method of correcting the zero position: If the 0 bit line is not aligned with the reference line, first loosen the screw with a screwdriver, adjust the position of the reference line with a wrench, align the reference line with the 0 taste line, and then tighten with a screwdriver. Tightening screw;

3. When measuring, the micrometer should be perpendicular to the workpiece to be tested, and the force measuring device should be rotated. When the measuring surface touches the workpiece to be tested, the force measuring device should be gently rotated. When the measuring device emits a slight “cha  cha ...” sound, This is the actual size of the workpiece being tested ;

4. The locking device can passively measure the forward and backward movement of the micro screw. Relax to the right and lock to the left ;

5. When measuring, the left hand should hold the heat shield to prevent the body temperature from being transmitted to the micrometer, causing measurement errors;

6. One end of the wrench can be adjusted to zero position, and the other end can tighten the force measuring device.

1. The micrometer is a precision measuring tool. When using it, it should be handled gently. After use, apply anti-rust oil to the exposed parts and put it into the box to prevent it from being dry and ventilated.

2. Do not force the micro-cylinder during the measurement to avoid damage accuracy.

3. Do not move the differential cylinder more than 25.5mm to the right to avoid damage to the micrometer and its accuracy.

4. Do not attempt to remove the parts of the micrometer to cause damage and cannot be used.

5. The verification period of the outer diameter micrometer should be determined according to the specific conditions of use.
