Troubleshooting

Symptom A: Unit does not power up or loses power occasionally (or backlight-
ing does not operate.)
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: Battery contacts may be making poor contact. Remove bat-
teries and pull metal contacts up from bottom of compartment and above
height of plastic knob using needle-nose pliers. See illustration below.
Symptom B: Unit is inaccurate.
Solution 1: Temperature of the grain and unit
may be more than 20˚F (11˚C) different. Follow
preheat procedure (page 5).
Solution 2: If grain is at an extreme tempera-
ture, 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 stabilize near room temperature. In-
spect for visible moisture on grain and inside test
cell. Dry test cell with soft cloth or blow dryer, if
necessary. Retest grain. (See page 6).
Solution 4: If the tester displays SYSTEM BAT-
TERY LOW, the test results may be inaccurate.
Replace battery.

factory. Return tester to your Agratronix dealer
for repair or replacement or call Agratronix cus-
tomer service at 1-800-821-9542.
Symptom C: Unit reads MOISTURE BELOW LIMIT or MOISTURE ABOVE LIMIT.
Solution 1: Grain may be too wet or dry to test. Check moisture limit guide-
lines on page 9 of Operating Instructions. NOTE: Limits shown on Page 9
are only guidelines.
