2. BELOW AND ABOVE LIMIT INDICATORS. Moisture readings
below 8.0% will be displayed as "<8.0%". Readings above 45.0%
will be displayed as ">45%".
3. The HT-PRO will display "<8.0%" in open air. (If open air reading
of higher than 8.0% is displayed, the tip probably needs cleaning.
Clean tip and re-calibrate tester.)
4. Temperatures can be measured from 32˚ to 225˚F (0˚ to 107˚C).
Make sure to allow the tip of the probe to adjust to the bale
temperature. This can take a minute or two.
5. The tester measures only the hay in contact with the tip of the
probe. Because moisture may vary widely in different parts of the
windrow, it will vary within each bale. Take readings in at least
five (5) places in the bale and use the HIGHEST reading as a
guideline. Consult your local experts for recommended baling
moisture.
6. Your tester is for reading moisture in hay. Placing a probe in 100%
moisture – water – will NOT result in a reading of 100%.
TESTING VARIABLES
Many variables affect the accuracy of your HT-PRO's readings. An
understanding of them can help you get the most from your tester.
A. Bale Density: In general, higher density bales of the same hay
moisture will read higher than lower density bales. Compaction of
the hay also varies within each bale.
B. Natural variations within the plant before proper curing: The
higher the moisture content, the wider the variations. Greater
uniformity can be expected as more curing takes place.
C. Sweating: Higher readings may occur during the first couple of
days after baling. Immediately after baling, moisture readings may
be low and then climb during the "sweating" process. As the hay
cures, moisture readings should drop and continue to decline, as
the hay becomes progressively drier. It is important to continue to
monitor moisture for several days.
D. Some preservatives increase conductivity initially: Until
the preservative is absorbed, usually in 1–2 days, it may cause
moisture readings to be 2–4 points above the same hay which is
untreated.
E. % of grass in the hay: Your HT-PRO has been calibrated on
100% alfalfa hay. The more grass in the hay, the higher the
moisture reading is compared to actual.
IMPORTANT: PLEASE READ
Because of the numerous variables which affect your HT-PRO's
readings, the indicated moisture content should not be used as an
absolute, quantitative measurement. Your tester's readings are,
however, very useful guidelines for safely baling and storing hay.
TESTING HINTS:
Because the inside of each bale is not uniform in density or leaf-to-
stem ratio, moisture readings with your HT-PRO will vary from one
part of the bale to another. It will read highest if the probe is inserted
