Threenshi YS series multi-functional test components are optional accessories of YS series Spectrophotometer s, which can be used for the reflection color measurement of high-concentration liquid reagents, sauces (such as tomato sauce, paint), powder (such as coffee) and other samples .
1. The YS multi-functional test component should be used in conjunction with the YS series Spectrophotometer . Before use, the YS series Spectrophotometer should be calibrated professionally for black and white calibration.

2. Place the YS series color measuring instrument as shown in the figure. The measuring port of the color measuring instrument should be well connected with the measuring port of the bracket. At the same time, the two base baffle pins should be aligned with the base plate reference holes of the YS color measuring instrument, and then Hold the push plate against the Colorimeter, tighten the screws, and check whether the Colorimeter is loose, and if it is loose, be sure to tighten the screws again.

3. Put the cuvette loaded with the sample to be tested into the bracket. Gently push away the rotatable pressure plate, gently put in the cuvette, one side of the cuvette is close to the measuring port of the instrument, and the other side is pressed by the rotatable pressure plate; note that the height of the liquid in the cuvette should be greater than the matching height of the test caliber (ie sample height reaches more than half a cup).
4. Cover the cover to ensure that the interior of the cuvette is completely dark. After completing the above steps, you can use the YS series Colorimeter to measure the reflected color of the sample.
