The linearity of the measurement data of the Metal gloss meter, from the principle of the gloss instrument, we can infer that the linearity of the measurement data of the instrument is an important factor related to the quality of the instrument. If the gloss standard plate is accurate, for example, the gloss of the standard plate is 95.5, then the measurement data for materials with a glossiness near 95.5 is generally accurate, but for materials with a gloss far away from the standard plate, the measurement data is accurate, It is necessary to ensure that the linearity of the instrument measurement system is excellent. The linearity of the instrument to measure the acquisition system is a difficult point in the design of the gloss instrument.

The standard plate of the Metal gloss meter must be well protected:

For the measurement of gloss, the data of the gloss standard plate must be used as the reference standard. If the standard plate is inaccurate, the instrument must be inaccurate. Moreover, the gloss of the standard plate is very easy to be stained, so the standard plate of the Metal gloss meter must be well protected. Generally, a special base is used, and the standard plate is embedded in the base to avoid external pollution and scratches. The standard plate contamination self-diagnosis function must be provided, that is, if the standard plate is contaminated, the instrument can identify and prompt the user to clean the standard plate. Otherwise, the calibration is wrong, and all measurement data will be inaccurate.
