IMPORTANT CALIBRATION NOTES

The GMT-Grind Grain Moisture Tester should be calibrated to match a
reference moisture tester before using it.
See instructions on page 10-5.
If the display shows "- - - -" or "++++", the measured moisture is out of range.
"- - - -" means that the sample is too dry.
"++++" means that the sample is too wet or that the grinder is short-circuited.
If you feel that the sample is within the moisture range, try using a larger test
sample. For example, test 11 ml instead of 9 ml.
NOTE: Store the tester in a dry place, preferably at room temperature. Do not
drop the tester or get it wet. Remove the battery when storing the tester for
long periods of time or when not in use.
