The Application of Micrometers

What we should notice in the Micrometer measuring

, following are some points for using all kinds of Micrometers for reference.

1. Before using a micrometer, It must return to zero, depth micrometer to be zero should be in a platform, inside micrometer calibration must apply the stand regulator, if the device is of a micrometer with a test of force. Force to be the same with measurement

2. Depth micrometer returns zero, the first to get the measuring rod back to the base and put the base on a platform,Then get the measuring rod down to the platform slowly.

3. Outside micrometer returns zero, make the measuring rod with the test anvil contact slowly. It should need the calibration rod. The right force between 2 ~ 3N.

4. When measuring, we generally required to zero for more than twice acorrding to factor that the measuring is unstable.

5. For using outside micrometer to measure, the non-one-hand manipulation is required. It's best to use micrometer Foot base or other auxiliary equipment.

6. As for micrometers are the precise measuring instruments, taking into account the repeatability of the measurement of factors, measuring should take on more several times.

7. Internal Micrometers are mostly three-point-contact measurement, measuring from top to bottom should be aware of its location and the vertical situation 8. After measurement, the micrometer should return to zero again , if the indication error is not zero but more than 0.002mm, you need to re-measurement or calibration You will find all kinds of Micrometers in Tresnainstrument. They supply precise measuring instrument.
