  • Page 4: Introduction

    Navigator™ family of meters. Delmhorst moisture meters are known to hay producers worldwide for their unmatched reliability and ease of use. The FX-20 is the ideal tool for hay producers large and small. It offers the latest in features and functionality. The FX-20is packaged in a robust and ergonomically designed ABS case (patent pending).

    Cal Check feature or external MCS calibration standard) to ensure the meter is working correctly and electrically accurate. Proper Use: When used properly, the FX-20 can help users make informed decisions on the hay moisture levels throughout production and storage. A moisture meter is a secondary method of determining moisture content, and users should be aware of other potential influences on the accuracy of conductance meter readings.

    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.

  • Page 24: Factors Affecting Your Readings

    Range of Moisture Content The FX-20 is designed to test moisture in hay over a range of 6%-40%. Readings over 30% should be used only as a qualitative indication of high moisture content. Delmhorst moisture meters use the relationship...

  • Page 25: Curing

    existing between electrical conductivity and moisture content in hay. As moisture content increases, so does the conductivity. Tests on hay at high moisture content, over 25%, are less accurate. This is mostly due to the variability in moisture distribution. The reduced level of accuracy in the high range does not significantly affect the usefulness of the meter, as a few high readings indicate that some action be taken to dry the hay to avoid spoilage or even self-combustion.

  • Page 26: Density

    Density The calibration of the moisture testers applies to bales of normal “average” density. Generally: • Denser bales may yield readings 1-2% higher. • Looser bales tend to yield 1-2% lower. • Tests in stacks usually yield readings 2%-3% lower. •...
  • Page 27 35%. More tests must be made whenever the variations among readings are greater. If there is a possibility of high moisture areas, samples from these locations should be taken. Areas of high moisture content will spoil, resulting in loss. It is extremely important to note the high readings and the frequency at which they occur.
