One-button measuring instrument, also known as image measuring ruler and flash image size measuring instrument, is the representative of a new image measuring technology. To explain the related knowledge of one-click image measuring instrument from the perspective of measuring structure, principle, function, advantages, disadvantages and practical application. What are the advantages and disadvantages of one-button measuring instrument?

Advantages:

1. The measurement speed is extremely fast, which can complete the drawing, measurement and tolerance evaluation of 100 sizes within 2 to 5 seconds. The efficiency is dozens of times that of the traditional quadratic image measuring instrument.

2. Abbe error which is affected by the increase of measurement stroke is avoided. The repeated measurement accuracy is high, to solve the same product repeated measurement data consistency is poor phenomenon.

3, the structure of the instrument is simple, do not need displacement ruler grating ruler, in the measurement process does not need to move the table, so the stability of the instrument is very good.

4. Because the precision ruler is the pixel of the CCD camera, and the pixel does not change with time, nor will it be affected by temperature and humidity, the accuracy of the instrument is relatively stable, and the measurement accuracy can be automatically calibrated by software.

Disadvantages:

1.  the measuring range is small, its measuring range is not more than 130mm under the condition of ensuring high precision.

2. the measurement function is relatively narrow, only suitable for the plane basic geometric size measurement and tolerance evaluation.

3. the product requirements are relatively high, for the product contour is not smooth, not fine product measurement error is relatively large. It's quite expensive.
