The microprocessor monitors the sample's weight loss during the entire testing process.
Simultaneously, if using the Predict ending criteria, the microprocessor is predicting a
final moisture concentration based upon the sample's rate of weight loss compared to the
exponential portion of a standard drying curve. Testing continues until the predicted
moisture concentration agrees within a certain percentage of the actual moisture
concentration appearing on the display. The percent agreement between the predicted
and the actual moisture concentrations will vary depending upon the system's
programming and the moisture level of the sample.
The MAX
®
4000 is an extremely flexible instrument. This flexibility means that some time
is required to determine the best set of parameters for a particular application. The
determination of the proper parameters requires a series of tests and good laboratory
procedure. Call your AZI technical sales representative for assistance developing Test
Programs for your samples.
