Troubleshooting

Symptom A: Unit does not power up or loses power occasionally.
Solution 1: Press ON-OFF button for shorter time. Do NOT hold button down.
Solution 2: Check batteries for 0% or higher. Replace as necessary.
Solution 3: Confi rm all four batteries are properly oriented.
Symptom B: Unit is inaccurate.
Solution 1: Temperature of the grain and unit may be more than 40˚F different.
Follow preheat procedure (See page 4).
Solution 2: If grain is at an extreme temperature, let grain settle to reach room
temperature — Retest grain.
Solution 3: Grain and/or test cell may have developed surface moisture from
rapid change in temperature of the grain sample. Allow grain and tester to stabi-
lize near room temperature.
Inspect for visible moisture on grain and inside test cell. Dry the test cell with a
soft cloth or a blow dryer if necessary. Retest grain.
Solution 4: If the tester displays BATTERY LOW, the test results may be inaccu-
rate. Replace battery.
Solution 5: Check for lodged grain under cell top ring and use weight test under
settings menu (see page 10). Grains that are smaller in nature or carry debris are
more likely to get lodged. For cleaning instructions, see page 18.
Solution 6: Unit may need to be recalibrated by factory. Return tester to your
Agratronix dealer for repair or replacement or call Agratronix customer service at
1-800-821-9542.
Symptom C: Unit shows MOISTURE BELOW LIMIT or MOISTURE ABOVE
LIMIT.
Solution 1: Grain may be too wet or dry to test. Check moisture limit guidelines
on page 3 of Operating Instructions.
NOTE: Limits shown on page 3 are only guidelines and subject to change.
