3. Material (Hay) Temperature
Info: The FX-20 has been calibrated at 80°F on various samples of
different types of hay, mostly alfalfa, and on different cuttings and
mixtures. The higher the temperature of the sample, the higher the
meter readings will be. Temperatures lower than 80°F cause lower
meter readings. The correction is approximately 1% point for every
20° difference. For best accuracy, use the temperature
correction in the meter, especially when working in extreme
environments (outside 50-90°F or 10-32°C) and environments
subject to temperature variation such as baled hay in storage.
Use: When active, press the left and right buttons to adjust the Material
Temperature down or up. Holding the left or right buttons will
cause the temperature to change more rapidly.
