When measuring a textured object, due to the influence of the texture, for a measuring instrument with a smaller caliber, the data will vary greatly with the different measurement positions during each measurement. For more accurate measurement, you can measure different positions multiple times and take the average value: or use a 16mm large-caliber measuring port for measurement.
When measuring objects with uneven surfaces, you can use the large-diameter measuring port with a glass protection plate to flatten uneven surfaces.
