[Chongqing] Neijiang outside micrometer, special outside micrometer, outside micrometer election Bohai Heavenly

[Bohai Heavenly recommend to you the star product - outside micrometer] outside micrometer judgment calibration zero error of good micrometer, when the micrometer screw and anvil contact movable horizontal zero line on the scale and fixed on the scale horizontal line should be aligned. If not aligned, the system will generate an error when measuring - zero error. If you can not eliminate the zero error, you should consider their impact on the readings. When the movable scale at the level above the horizontal zero line, and the first line and the horizontal scale x strip aligned measurement readings that illustrate the true value is less than x / 100 毫米 Tianjin outside micrometer, which is called a negative zero error zero error; if movable scale horizontal zero line at the bottom level of the outside micrometer, and the first line and the horizontal scale bar y aligned, then the readings measured value is greater than the real y / 100 毫米 deals outside micrometer This error is called zero plus zero errors. For the existence of zero error micrometer measurements should be equal to the reading minus zero error, that is, objects length = fixed scale reading + movable scale readings - zero error. [Bohai Heavenly recommend star product - outside micrometer precision micrometer] and adjustment: micrometer is a very broad application of precision measuring tools, according to its manufacturing precision, 0 and 1 can be divided into two types, 0 higher-level accuracy, a second. Micrometer precision manufacturing, mainly by its indication error plane parallelism and anvil surfaces to determine the size tolerances outside micrometer price, small size, precision micrometer. From precision micrometer seen, with micrometer-level accuracy IT6 ~ IT10 part size is more appropriate. Micrometer in use, due to wear and tear, especially the use of wrong time, will show error micrometer ultra-poor, it should be checked regularly, washable or necessary adjustments to keep micrometer accuracy.
