15. false apparent weight loss If not compensated for this error leads to erroneous moisture results too high The amount of lift generated by the hot sample varies from sample to sample and increases with the test temperature gt n some cases the lift is approximately 5 milligrams and is small enough that less sensitive instruments do not provide compensation The lift must be compensated for when testing low moisture samples For example some plastic resins are controlled to a moisture content of 0 01 so for a 30 gram sample the weight change is only 3 milligrams Similarly some lyophilized drugs are so valuable that the sample weighs only 150 milligrams At 2 moisture the weight change is only 3 milligrams gt The MAX 5000 has an adjustable lift compensation based on the Memory Start Each instrument is characterized for lift produced under standard conditions and for the way that lift changes for various test temperatures The lift compensation can be adjusted by setting the Memory Start lift to a value other than 100 Use 100 for all samples unless it is found by experiment that another value is more appropriate Most users will not need to adjust this value Contact your AZI technical sales representative at 800 528 7411 for help on determining the proper value for difficult applications gt Low Moisture CF For extremely low moisture products a compensation factor can be used to align MAX 5000 results to the reference st
