IMPORTANT NOTE: When turning G-
7 “ON”, allow it to run through its entire initialization
before pressing any keys. Any interruption to the initialization (“power up”)will result in a
“Calibration Fail” when performing a calibration check. If this occurs, reset the meter,
power it down, and then power it up properly.
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. The upper electrode screws down over the sample
cup. Both discs have sharp points that penetrate the seed coat and make contact with the
interior of the grain.
This system rests on a pressure plate that is mounted on a pretensioned calibrated spring,
insuring uniformity of pressure from one test to another for optimum repeatability.
The G-7 has been calibrated against well-conditioned samples whose moisture content was
