Attention

This instrument is a professional jewelry appraisal instrument, and the operator needs to have a certain jewelry appraisal ability to be proficient in the use of this instrument;

After the absorption line or band appears, if continuously reduce the brightness of the light source , the absorption band or absorption line will widen. This phenomenon is caused by the weakening of the light source brightness. The widened absorption line or band is not characteristic absorption. We generally record the position and intensity of the absorption line or band that appeared at the beginning;

The light entrance aperture should be small rather than large. When the test is not ideal, the light entrance aperture should be adjusted properly before testing;

Shut down according to the operating sequence required in this manual, do not force shut down at will

The size of the lock aperture needs to be determined according to the nature of the gemstone. In general, the better the transparency of the gemstone, the smaller the lock aperture should be, no more than 6mm
