| Abstract: | The instrument for textile-testing of transmission of ultraviolet ray can evaluate the ability to counteract the UV of textile. The deuterium lamp is often used as ultraviolet ray lamp in UV measuring instrument, the measuring accuracy of the instrument has close correlation with the stability of radiation energy. The suitable amplifying circuit and analog to digital circuit are also importance to ensure the measuring accuracy. The method of improving measuring accuracy is introduced by using the feedback and compare technology. It has been applied to UV measuring instruments. |
