CHECK CALIBRATION hRemove the prod from the top of the meter. hPress the calibration check key @ . Meter is in calibration if the needle pointer moves to “20” on the scale. Any reading within the green band on the dial is acceptable.
F-6 manual B&W_F-6 manual B&W.qxp 1/25/13 11:40 AM Page 6 hIf you are testing high density bales, we recommend using the H-4 handle with the 830-2 10” prod, 830-3 18” prod, or the 830-4 36” prod. Using the handle/prod combination eliminates stress on the instrument case and the panel meter that may occur when trying to insert the prod into a high density or large bale. hWhen using the 36” prod, be sure to guide the prod into the bale with one hand while pushing on the H-4 handle.

Use the highest readings.
F-6 manual B&W_F-6 manual B&W.qxp 1/25/13 11:40 AM Page 8 Range of Moisture Content The F-6 is designed to test moisture in hay over a range of 6%-30% or 13-40%, depending on model. Readings over 30% should be used only as a qualitative indication of high moisture content. Delmhorst moisture meters use the relationship existing between electrical conductivity and moisture content in hay. As moisture content increases, so does the conductivity.
F-6 manual B&W_F-6 manual B&W.qxp 1/25/13 11:40 AM Page 9 The validity of the meter readings is closely related to the care spent in sampling the hay to be tested. Whether hay in the windrow or baled hay is tested, the number of tests made should be increased whenever the initial readings show considerable variations. Density The calibration of the moisture testers applies to bales of normal “average” density. Generally: hDenser bales may yield readings 1-2% higher. hLooser bales tend to yield 1-2% lower.
F-6 manual B&W_F-6 manual B&W.qxp 1/25/13 11:40 AM Page 10 Sample Size When testing baled hay, it is essential to take readings at several different points in the bale. Hay moisture may vary a great deal in the same bale. For example, at one point bale moisture may be 20% and at another over 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.
