What is the reason why the grating ruler of image measuring instrument does not count? Post time: 2020-03-24 Source: https://www.microaccuracy.com/ The image measuring instrument uses an optical non-contact measurement method. The grating ruler is a very important measurement feedback device for the equipment and can be used as a linear displacement or angle For the detection of displacement, what is the reason why the grating ruler of the image measuring instrument does not count? The grating ruler has the characteristics of large detection range, high detection accuracy and fast response speed. It plays an important role in the image measuring instrument. If there is a problem with the grating ruler during the measurement process, the accuracy of the measurement will be affected, and the grating ruler will not count. The reasons are as follows: The first case: When the Y-axis count of the image measuring instrument is the same as the X-axis count, the operator should insert the X-axis grating ruler on the Y-axis, and then check whether the technology on the Y-axis Normal, if the count on the Y-axis is normal, then the X-axis grating ruler is normal. At this time, the user can consider that it may be the digital display or the software X-axis resolution setting is not normal, or the grating ruler may be inserted incorrectly. It's caused by location. The second case: the technology of the grating ruler on the Y-axis of the image measuring instrument is not normal. At this time, you should first determine whether the X-axis can move normally. If it can be moved and there is no relative displacement between the grating scale reading and the ruler body, then the user You should check whether there is any oil on the grating ruler joints. If there is, clean it up in time. If not, you can confirm that the X-axis grating ruler is damaged. Just replace the grating ruler. The above are the common reasons why the grating ruler does not count. The grating ruler is a very important sensor of the image measuring instrument. Therefore, it is necessary to pay attention to the measurement and use process, so as to reduce the measurement error. Miaoji Technology has been focusing on the Ru0026D and production of precision measuring equipment for many years. Currently, it can provide a variety of high-performance image measuring instruments, one-button measuring instruments and other equipment!
