The following are the general operating procedures for the VMA - F Semi - auto Video Measuring System by Mikrosize Equipment Supplier: Ⅰ. Pre - operation Preparation 1. Equipment Inspection: Check the appearance of the equipment for any damage, ensure that all components are firmly connected, the power supply is normal, and the data cable is correctly connected. Clean the worktable surface, lens, light source and other components of the instrument to prevent dust or debris from affecting the measurement. 2. Power - on the Equipment: Turn on the power of the computer host and monitor, and wait for the computer to start up completely. Then turn on the power switch of the VMA - F Semi - auto Video Measuring System, and wait for the equipment to complete self - inspection to ensure that all functional modules are initialized normally. 3. Launch the Measurement Software: Click the corresponding shortcut of the measurement software on the computer desktop to enter the measurement software interface. Check whether the software version is applicable and whether all parameters are set to the default correct values. Ⅱ. Sample Preparation 1. Select the Sample: According to the measurement requirements, select an appropriate sample to be measured, ensuring that the sample size is within the measurement range of the video measuring system, and the surface is clean, free of oil stains, and without obvious scratches or other defects that may affect the measurement. 2. Fix the Sample: Place the sample on the worktable of the video measuring system, and use clamps or other fixing devices to firmly fix the sample to prevent it from moving during the measurement. Pay attention to making the measurement surface of the sample parallel to the worktable and as close as possible to the center of the worktable to better obtain the image and conduct the measurement. Ⅲ. Measurement Operations 1. Adjust the Optical Path and Parameters - Focus Adjustment: Adjust the focus adjustment knob of the video measuring system to make the image of the sample clearly presented on the monitor, ensuring that there are no blurring, double - imaging or other phenomena. - Light Source Adjustment: According to the material, color and surface characteristics of the sample, adjust the brightness and angle of the light source to obtain the best lighting effect, highlighting the features and contours of the sample for accurate measurement. - Magnification Selection: Select an appropriate magnification according to the size of the sample and the measurement accuracy requirements. This can be achieved by rotating the zoom lens or setting the corresponding magnification option in the software. 2. Positioning and Point - Finding - Manual Worktable Movement: Use the manual operation handle of the video measuring system or the movement buttons in the software to move the sample on the worktable so that the part to be measured is located at the center of the field of view. - Automatic Edge - Finding or Manual Point - Finding: Utilize the automatic edge - finding function of the software to enable the video measuring system to automatically identify the edges or feature points of the sample. For some complex - shaped samples or cases where automatic edge - finding is inaccurate, the manual point - finding tool can also be used to accurately click on the points or positions to be measured on the image. 3. Measurement and Recording - Select the Measurement Tool: Select the corresponding measurement tool in the software according to the measurement requirements, such as tools for measuring length, width, angle, circle diameter, radius, etc. - Conduct Measurement Operations: Use the selected measurement tool to operate on the image according to the prompts. For example, click to measure the distance between two points, select the edge of a circle to determine the diameter, etc. The software will automatically calculate and display the measurement results. - Record the Data: Record the measured data. You can directly save the measurement data file in the software, or manually record the data in a paper form or an electronic document for subsequent analysis and reporting. 4. Complex Measurements and Settings - Create a Measurement Program: If repeated measurements are required for multiple identical or similar samples, a measurement program can be created in the software to save the measurement steps, parameters and sequence. The program can be directly called for the next measurement to improve measurement efficiency and accuracy. - Coordinate System Setting: Set an appropriate coordinate system in the software, such as a rectangular coordinate system or a polar coordinate system, according to the characteristics of the sample and the measurement requirements to facilitate measurement and data processing. - Tolerance Setting and Judgment: For measurements with tolerance requirements, set the corresponding tolerance range in the software. The software will automatically compare the measurement results with the tolerance, judge whether they are qualified, and give corresponding prompts. Ⅳ. End - work Procedures 1. Close the Software and Equipment: After the measurement is completed, first save all relevant data and files in the measurement software, and then close the measurement software. Turn off the power switch of the VMA - F Semi - auto Video Measuring System, and finally turn off the power of the computer host and monitor. 2. Cleaning and Maintenance: Remove the sample, wipe the worktable surface with a clean cloth, and clean up any possible remaining debris and dust. If there are stains on the instrument surface, an appropriate cleaning agent can be used for wiping, but be careful to avoid liquid from entering the interior of the instrument. Regularly maintain the video measuring system, such as cleaning the lens, calibrating the accuracy, etc., to ensure that the instrument is always in good working condition. 3. Data Sorting and Reporting: Sort and analyze the measurement data, and generate a measurement report as needed, including measurement results, tolerance judgment, sample information, etc., for subsequent quality control and product research and development. |
