The parameters and maintenance methods that need to be paid attention to when the image measuring instrument is accepted.

1. Measurement error of the image measuring instrument on the plane Exy: The measurement error represents the indication error of placing the product or sample in any direction on the imprinting measurement plane to measure the two-dimensional ruler.

2. Size measurement error of the image measuring instrument on the Z axis Ez: The measurement error represents the indication error measured in the direction perpendicular to the imprint measurement plane and in the uniaxial direction. 3. The scale measurement error Ev of the measuring head of the image measuring instrument: there is no movement in the channel, and any scale indication error is measured in the imprinted field of view plane. 4. The consistency of the measurement results of each cross section measured by the image measuring instrument: When the impression measuring instrument measures on different cross sections of the optical axis, the consistency of the coordinates of each section and the projection of the origin of the XY plane can be It is understood that when the indentation measuring instrument moves up and down in the Z direction #, the perpendicularity between the Z axis and the XY horizontal plane can also reflect the consistency of the measurement characteristics of the measuring head at different heights. 5. The two-dimensional measurement error P2D of the image measuring instrument: use the indentation measuring instrument to measure the fluctuation of the standard circle radius. 6. Detection error PV of the measuring head of the image measuring instrument: Use the indentation measuring instrument to measure the fluctuation of the standard circle radius in the field of view. 7. The zoom exploration error Pz of the image measuring instrument: Use an indentation measuring instrument to measure the fluctuation of the indicated value of the standard circle center coordinate under different magnifications. Optical image measuring instruments are widely used in manufacturing and are closely related to people's lives. The profession is also showing a trend of rapid expansion. China's luminous impression measuring instrument professional mall is also accelerating the speed of mergers and acquisitions, and is far from the functions of foreign products. Several common methods of repairing image measuring instruments are inevitably in the process of using image measuring instruments. There will be large and small failures. We have encountered some small problems that can be solved. Of course, if we can solve them immediately, it will save a lot of time. So what problems can we solve smoothly? What methods do we use today to share some common methods: 1. Find problems by looking, smelling and touching. Just like a general circuit short circuit, there will be a burning smell and loose parts, you can feel it with your hands. 2. Troubleshoot some basic factors, such as circuit problems, electronic component problems, and venue location. 3. In some cases, you can try to replace accessories or electronic components to see if the situation will improve. For example: If the surface of the objective lens is blurred, please replace it with the same standard objective lens to see if it works, if it does not work, please go back to the next reason for troubleshooting. 4. Under long-term operation, especially in high temperature seasons. The temperature of the device itself will rise. This will affect the operation. At this time, the indoor temperature can be controlled, and may rise, and the machine can be cooled so that the central electronic components can work at room temperature. 5. Due to the aging of internal parts or other reasons, after a period of operation, many machines and equipment have been stopped, and it will automatically hang up in the middle of the application. At this point, you can temporarily stop and let the machine stop, after a period of time, and then turn it on again, maybe there will be better results.
