Operating Hay Tester (Moisture Test)
NOTE: If both temperature and moisture % switches are pressed
simultaneous-ly, the tester will not be harmed but a meaningless number
will be displayed.
1. Insert probe tip into hay so both brass pieces are in contact with hay.
Hay Testing Guidelines for probe in-formation and hay preparation.
2. Press "Temperature" switch.
Because the metal tip of the probe must adjust to the temperature of the
bale, it may take from 1-2 min-utes until the correct temperature
stabilizes. It is not necessary to keep the switch depressed for this period.
Just leave the probe in the bale and periodically check the reading to
allow the metal tip of the probe to adjust to the bale temperature. The
temperature circuitry of each tester is individually calibrated to its probe. If
a replacement probe is installed, the temperature readings may be off by
1˚ to 3˚ from actual.
IMPORTANT: Temperature may vary widely in different parts of the
bale. Take readings in at least five (5) plac-es and use the HIGHEST
reading as a guideline.
Troubleshooting the Hay Tester
If tester fails to operate, follow these steps:
1. If no display appears when switches are pressed, check battery
connections
2. If "LOWBAT" is displayed, replace battery with a new 9 volt
alkaline battery.
If tester displays inaccurate read-ings, or if readings are lower than
actual, follow these steps:
3. Make certain cord connection (A) between tester and probe is
dry and fastened correctly.
4. Clean tarnish from probe tip (B) and retest hay.
5. To check tester calibration, take a "Moisture %" reading at room tem-
perature (72˚F) with nothing touch-ing the end of the probe.
• Test reading should be 14.5% (+/–1%).
Short two brass parts of probe tip with a piece of aluminum foil and take a
second "Moisture %" reading.
• Test reading should be 45.0% (+/–1%).
