Troubleshooting
Symptom A:
Unit does not power up or loses power occasionally (or backlighting
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 batteries
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 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 stabilize near room temperature.
Inspect 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
BATTERY LOW, the test results may be
A
A
inaccurate. Replace battery.
