Common faults and related solutions of automatic video measuring machines

Common faults and related solutions of automatic video measuring machines:

1. Issue: The image area does not display real-time images and appears blue. How to solve this?
Analysis: This may be due to improperly connected video input cables, incorrectly inserted into the video input port of the computer’s graphics card after connecting to the computer host, or incorrect video input signal settings.

2. Issue: The image area within the video measuring machine displays no images and appears gray. Why is this happening?

2.1 This could be because the video capture card is not properly installed. In this case, turn off the computer and the instrument, open the computer case, remove the video capture card, reinsert it, confirm proper insertion, and then restart the computer to resolve the issue. If you change the slot, you need to reinstall the driver for the video measuring machine.
2.2 It may also be due to the video capture card driver not being installed correctly. Follow the instructions to reinstall the video card driver.

3. Issue: Anomalies in the data area count of the video measuring machine.

3.1 This may be caused by poor connection of the RS232 or grating ruler signal lines. In this case, remove and reconnect the RS232 and grating ruler signal lines to resolve the issue.
3.2 It may also be a fault caused by incorrect system settings. Follow the instructions to set the linear compensation values for the three axes.

4. Issue: Why can’t I move the Z-axis of the video measuring machine?
Analysis: This may be because the fixing screw of the Z-axis is not removed. In this case, loosen the fixing screw on the column. Alternatively, it could be a faulty Z-axis motor. In this case, please contact us for repair.

5. Question: What is the difference between optical magnification and image magnification?
Optical magnification refers to the magnification of an object through the eyepiece by the CCD image sensor. Image magnification refers to the actual magnification of the image compared to the object. The difference lies in the method of magnification; the former is achieved through the structure of the optical lens, without distortion, while the latter involves enlarging the pixel area within the CCD image sensor to achieve magnification, falling under the category of image magnification processing.
