Page 5: Introduction
INTRODUCTION The M-3G/M-20P Portable Moisture Tester is very simple to use and very intuitive in its operation. The M-3G and M-20P are identical, except that the M-3G offers four grain capability, while the M-20P can test twenty individual grains. Operating and file handling instructions are also virtually identical and will be treated as such. - Page 6 OPERATOR’S MANUAL 4 INTRODUCTION M-3G/M-20P Operation and File Handling 11001-1361-200512...

The M-3G can hold four calibration files. It typically comes from the factory installed with three products. This allows one grain to have a low and a high range (usually corn). Thus, the M-3G can hold up to four products, fewer if multiple ranges are used for a product. -
Page 12: Averaging
Bias Factor AVERAGING The M-3G and M-20P have 10 registers for storing 10 moisture values to be averaged. Each register is identified with a number (#1, #2, #3...#10). An added value is placed in the next open register. If all registers are full when adding a new value, the value in register #1 will be replaced with the new value being placed in register #10. - Page 13 3.

6. Using the computer, determine how many product files are currently in the unit. If all 4 product file allocations are being used on the M-3G, or all 20 allocations are being used on the M-20P, one must be deleted if a new one is to be added. - Page 17 A diagnostic file may be used to convey information to the computer regarding the last test run on the M-3G or M-20P. To develop this file in the unit, the diagnostic mode must be enabled (a menu selection under the Setup screen).
