Troubleshooting the Hay Tester

If tester fails to operate, follow these steps:
1. If no display appears when switches are pressed, check battery connec-
tions.
2. If "LOWBAT" is displayed, replace
battery with a new 9 volt alkaline
battery. (See Replacing 9 Volt Alka-
line 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%).
If tester fails to display above readings, replace tester.
