    INTRODUCTION Thank you for purchasing the G-7 Grain Moisture Meter. The G-7 is a full-featured meter that incorporates a double disc, pressure type electrode. The lower disc forms the base of a shallow cup in which the grain sample is placed.

    + 0.5% in the range 9 to 17 and + 1.0% in the range 17 to 23. The operating instructions for the G-7 are divided into three sections. Section A (Meter Operation) is a step-by-step guide to the different features and basic use of your moisture meter.

The 4-minute timer is user-adjustable. #2 – ENTER The ENTER key accepts a selection you make for the various functions made available through the menus.

  • Page 5: Temperature Mode

    TEMP. MODE – The G-7 defaults to a temperature of 80°F. As grain temperature increases, indicated moisture content rises. Lower grain temperatures result in lower indicated moisture content. The temperature modes are: AUTOMATIC: A built-in temperature sensor measures the temperature of the grain sample.

    Before changing the offset, we recommend that you determine the average of at least three tests with the G-7 on the sample that was tested with the elevator meter. If you accept the elevator moisture meter as a standard, then adjust the %MC offset to match the elevator.

  • Page 12: Section C: Factors Affecting Your Readings

    SAMPLE SIZE  The G-7 tests a small sample and therefore its reading is directly related to the moisture content of the grain from where the sample was selected.  If the initial two or three tests indicate uniform moisture content, there is no need to make additional tests on other samples.

    a moisture content too high for safe storage.  It is more important to know the range and distribution of moisture in stored grain than it is to know the average moisture content, since an average may not reveal the presence of high moisture pockets.
