This surface should not be vibrating it can be but the more stable the more accurate the test weight measurement c There should not be a fan blowing directly on the test cell NOTE If the unit was not stable during the measurement process a warning will appear before the measurements are displayed It is recommended the tester be on a flat non vibrating surface for the readings to be accurate Any of these conditions will result in the grain test weight taking a longer time to measure and not being as accurate as it can be if these conditions are all met The entire test cell is sitting on a precision weigh scale mechanism that s why its important to keep it stable and not to drop the unit or damage may occur FOR BEST GRAIN MOISTURE RESULTS a The closer the grain and test cell temperature are to each other the better the results b The tester compensates for temperature but the grain and test cell temperature should be within 40 F of each other for best results c Use the average feature and always average 3 consecutive tests from the same grain batch Grains such as corn that have a unigue geometry can sit in the test cell slightly differently each time and add some variance in your results so averaging 3 readings will give best results NOTE Though you can hold the unit in your hand for testing that is not recommended since its hard to keep your hand stable and level for the grain test weight measurement
