According to the principle of selection of measuring instruments, appropriate measuring instruments should be selected for measurement. The metrological work of measuring instruments should follow the maintenance, repair and appraisal plans of measuring instruments, and ensure the accuracy, sensitivity and accuracy of the gauges used. For the correct use of measuring instruments, please refer to the use instructions or relevant reference materials for light and light, keep clean, antirust, anti vibration, reasonable storage and storage.
One, flat plate
1, the steel plate is usually used for cold work and sample dressing; the cast iron plate can be used as a grinding tool, except for the steel plate use; the marble plate does not have to be coated with antirust grease and is less affected by the temperature, but it is easily deformed when the humidity is high.
The 2, 0, 1, and 2 grade plates are generally used for inspection, and 3 level plates are generally used for marking.
3, the flat plate is stable, generally adjusting the horizontal plane with three supporting points. The supporting points of large plates should be cushionless and stable, but they must not be destroyed, and the force must be uniform so as to reduce self weight and form.
4, the flat should avoid excessive wear due to frequent local use, avoid heat source and acid base corrosion during use.
5, flat panel should not withstand impact, heavy pressure or long time stacking of goods.
Two. The sample straight ruler and the flat ruler
1. When the ruler is used, it is not allowed to collide. The integrity of the edges should be ensured, and the holding part of the insulation plate should be held to avoid the influence of temperature on the accuracy and rust.
2. Before measuring, the measuring surface of the ruler should not be scratched, bruised or corroded. The surface should be clean and bright.
3. There should be no erosion, spots, scales, pits, cracks and other defects in the flat face. A flat ruler should be free of magnetic.
4, in general, different precision leveling rods should be selected according to different requirements.
Three. Right angle ruler
The 1, 00 and 0 level straightening square is generally used for testing precision measuring tools; 1 is used for testing precision workpieces; 2 is used for testing general workpieces.
2, before use, we should first check whether the faces and edges are bruised. The left side, right side and short side of the long side of the square are all workpiece faces (i.e. inside and outside right angles).  Clean the face of the ruler and the inspected face.
3. When using, the straightening angle ruler is placed on the working surface of the workpiece to be tested, and the light gap method is used to identify whether the angle of the workpiece is correct. Attention should be taken lightly, lightly and lightly to prevent distortion.
4. In order to find the accurate measurement results, the straightness angle ruler can be turned over 180 degrees again, and the arithmetic mean value of the two readings is taken as the result of the measurement, and the deviation of the angle ruler itself can be eliminated.
Four. The universal angle ruler
1, before using, the first universal angle wiping clean, and then check whether the interaction of each component moves smoothly and reliably, the reading after the stop is not moving, and then to zero position.
2, when measuring, the screw cap on the brake is relaxed, the main ruler seat is moved, and the hand on the back of the cursor is adjusted carefully until the two measuring surface of the angle ruler is in close contact with the working face of the measured workpiece. Then screw the nut on the brake to be fixed and read.
3. After the measurement is finished, apply the gasoline to wash the universal angle ruler, wipe it carefully with clean gauze, apply antirust oil, and then put it into the box.
Five, vernier caliper
1, before use, we should clean the dust and oil pollution on the surface of the workpiece and the measured workpiece, so as not to hurt the vernier caliper and influence the measuring accuracy, and at the same time check the interaction of each part. If the frame and micro motion are flexible, can the fastening screws work?
2, check the vernier caliper zero position, make the vernier caliper two claw close closely, observe without obvious light gap with the eye, observe whether the vernier zero line is aligned with the zero line of the ruler, and whether the end line of the vernier and the corresponding line of the ruler body are aligned. It is best to close the vernier caliper measuring claw three times to see if the readings are consistent. If the three reading is not zero, but the reading number is exactly the same as the three time, it can be recorded and corrected during the measurement.
3. When using, we should master the pressure of the working surface at the same time at the same time. It can not be too big or too small. It just makes the measuring surface contact with the workpiece. At the same time, the claw can also slide freely along the surface of the workpiece.  Vernier calipers with fretting devices should be used with fretting devices.
4. When the vernier caliper is read, the vernier caliper should be horizontally taken in the direction of light, so that the line of sight is perpendicular to the scale line read on the ruler so as not to cause reading error due to the skew of the line of sight. It is better to measure many times in the same position of the workpiece and get its average value.
5. When measuring the outer size, after reading the reading number, we should not pull the downstream marking card from the measured workpiece and open the claw out. After measuring the inner dimension reading, the quantity of the claw should be slid along the center line of the hole to prevent the skew, or the measuring accuracy will be affected by the wear, the sprain, the deformation or the movement of the scale frame.
6, you can not use vernier calipers to measure moving parts. In this way, the vernier caliper is easy to be seriously worn and easy to cause accidents.
7. No vernier callipers can be used instead of calipers to pull back and forth on the workpiece. When you use vernier calipers, you must not work hard against the work to prevent damage to vernier calipers.
8, the vernier caliper should not be placed near the strong magnetic field, such as the magnetic worktable of the grinder, so as not to make the caliper feel magnetized and affect the use.
9. After use, wipe the vernier caliper clean and put it in the special box, especially the large size vernier caliper. Attention to rust prevention, main ruler bending deformation.
Six. High vernier caliper
1, before use, check whether there are burrs or abrasions on the working face of the base, the working face of the base and inspection
