TESTING HINTS: IN THE BALE:
The way hay is fed into the baler's compression chamber results in more hay
towards the bottom than the top. And shattered leaves, etc., will sift downward
causing the bottom or "tight" side of the bale to be denser than the top or "looser"
side. (An exception to this is the Heston 4800 baler, which "folds" the hay into the
chamber on each side. The top 1/3 of the 1-ton bale and its upper corners are the
densest areas of the bale. 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 into the
"tight" side. Your meter will give higher readings in tight bales than in loose bales.
For best results: INSERT THE PROBE INTO THE "TIGHT" SIDE AT A
45˚ANGLE. Take readings in at least five (5) places, and use the highest
reading as a guideline. DO NOT AVERAGE RESULTS.
TESTING HINTS: IN THE WINDROW:
The HT-PRO™ has not been calibrated for use in the Windrow, however; we do
offer a Windrow Hay Moisture Tester please check with your local dealer or call
us for a dealer close to you. Windrow moisture will vary greatly in different parts
of the field. Thick, heavy sections of the windrow will contain much higher
moisture hay than thin areas. Look for "humps" in the windrows.
Check the windrows at several locations by turning the windrow up on its
side and selecting a handful of hay from the bottom. Hay from the bot-tom
should contain the most moisture, since the top of the windrow will dry out first.
Use the highest reading as a guideline for when to bale. DO NOT AVERAGE
RESULTS. There are more variables to testing moisture in the windrow than
in a bale. For greater accuracy, several bales should also be baled and
tested before the entire field is baled.
CALIBRATION CHECK (RE-CALIBRATION)
1. Clean the probe tip. While holding the probe in the air, press and hold the
button. The tester will begin to count down on the display "5,4,3,2,1" and the
tester will then display "00.0".
√
2. Release the
3.
Firmly place the calibration clip on to the probe
tip as shown in the clip illustrations below and
then press and hold the √ button.
The tester will now display 24.8%, indicating
4.
that the unit is now calibrated.
**If the tester displays "99.9" anytime during the calibration process, this indicates an
error has occurred. Try repeating the calibration procedure starting at Step 1.
BATTERY
1."LOBAT" will be displayed, if the battery is running low and needs replacing.
Always use an ALKALINE 9-volt battery.
2. After the battery is replaced, always re-calibrate your tester (see above).
NOTE: Your tester will display 44.4 briefly just after the battery is replaced. This
signifies that the tester has re-initialized. The last calibration and backlighting (on/
off) status will be utilized.
