Do you know what the influencing factors of customized Measurement instrument error are? Follow the editor to have a simple understanding!
1. Temperature
In general, when measuring length, in order to achieve the same measurement purpose, it is necessary to ensure that the temperature of the measured workpiece meets the international standard temperature of 20 ℃, so as to reduce the occurrence of non-compliance with the temperature requirement of the measured workpiece. The phenomenon of measurement error. Therefore, in order to further improve the measurement accuracy of the length measuring instrument and reduce the measurement deviation caused by the temperature error, it is necessary to strengthen the analysis and exploration of the cause of the workpiece temperature error. In order to reduce the temperature error, when measuring with a length gauge, the material of the measured object and the standard should be as consistent as possible to reduce the coefficient of linear expansion between the measuring object and the standard, thereby reducing the measurement error , In order to ensure the consistency of the temperature and reduce the influence of the temperature error on the measurement of the length measuring instrument.
2. The use and maintenance of the length customized Measurement instrument
When using a long customized Measurement instrument for measurement, improper use will cause errors in the measurement results. For example, in a horizontal length measuring instrument, a standard ring gauge and measuring block accessories need to be combined into a size that is the same as the measured ring gauge, and it is compared and measured with the measured ring gauge. In addition to the size of the customized Measurement instrument error, this measurement method will also produce alignment errors. There are many influencing factors that cause measurement errors, such as the brightness and contrast of the inspection site, the quality of the customized Measurement instrument's markings, the method of alignment, and the vision of the measuring personnel. In addition, if the length of the customized Measurement instrument is not properly maintained, the marking and accuracy of the measuring instrument will deviate, which will affect the measurement results. Therefore, whether it is in use or in storage, the length of the customized Measurement instrument needs to be well maintained.
