Page 4: Features
1. Features The Model AN-820 composition analyzer is a desk top grain tester (Transmittance type) that utilizes applied near-infrared rice analysis technology. It employs total-grain measurement formulas for measuring without crushing the sample grain to pieces, so it makes it possible to analyze grain quickly and easily. -

This consideration is “CM Protein” which is displayed as protein conversion by assuming the fixed moisture content (with AN-820, this is the same as the “@ Moisture %” is specified). When the fixed moisture content is assumed to be “ 0% ”, this is referred to as a “dry conversion”... -
Page 17: Manual Adjustment Mode
Manual adjustment mode With manual setting, prepare 3 or 5 samples and calculate the difference between average value of AN-820 and average value of standard samples for each composition. Because this alternative uses multiple samples to perform the bias adjustment, it is able to perform more accurate bias adjustment than automatic adjustment. - Page 18 Operation Display Explanation 1.

Page 24: Cleaning
10. Cleaning When the surface of AN-820 is found dirty, wipe it by soft cloth. If extremely dirty, wipe with wet cloth. Note : Do not use any volatile chemicals such as a thinner or benzene. Note : While measurement is in progress, some grain sample may be spilt out and is dropping on the tray of the bottom of AN-820. -

More than half a day before performing the measurements, take standard sample out of the cold, dark area and put it in the same environment as AN-820. After the sample returns to normal temperature, perform measurements. Measure the standard sample 3 or 5 times, find th average values for each composition, and then compensation of each. - Page 28 0904・AI・0101・030_S...
