1. Turn on the power of the instrument first, and warm up for about 30 minutes.

2. Clear and calibrate. Take the round black module and place it at the measuring place of the instrument. The black module should be marked with a clear number to check whether the product to be tested meets the standard, and gently wipe the module with a small brush to prevent foreign matter such as flour from entering and affecting the measured value. calibration.

3. Make a sample. Wipe the glass sheet clean, under the action of the powder knife, fill the module held by the backhand with the flour to be tested, remove the powder knife, press firmly with the small solid module, remove the small solid module, and buckle the white lid.

Note that during the preparation process, a small brush should be used to wipe clean the spilled flour on the module.

4. Put the prepared module (the black module) at the measurement place of the whiteness meter, with the groove facing downwards, slowly let go. After the value on the module is displayed on the instrument, then press the "calibration" key to remove the standard module .

5. Put the prepared flour module with the flour side up and place it in the place where the standard module is placed (the groove is facing down).

6. Press the "test" button on the whiteness meter to complete the test task and record the numbers on the notebook.
