Reliability – This feature is similar to Rate but is based on a percent of accuracy.
With reliability set to 99%, the test would end when the actual moisture loss was within 99% of the predicted result. A value may be set that would give exceptional results when the actual result is within 90 to 99 percent of the predicted result. This ending criterion
is less dependent on actual moisture loss than Rate.
Temp Then … – These features are used when rate or predict criteria alone would end the test after the release of free or bound moisture but before the full temperature is reached. The MAX 5000XL first checks to see that the temperature is within two (2) degrees of the test temperature before checking for the other criteria as previously described. This can be helpful for ashing, which takes a while to reach the final temperature, and testing ultra low moisture samples, which don’t readily release moisture at the beginning of the test.
Sample Size Options
This feature enters a target sample size and the minimum and maximum sample range. Sample size ranges can be programmed from 0.1 gram to
99.9grams. The total difference in values between size and window must be between 0 grams minimum and 100 grams maximum.
Sample Size - The sample size should be consistent for all tests on a particular product in order to get the best standard deviation possible. High volatile
materials, such as coatings, typically require smaller sample sizes (one to three grams). Low moisture materials, such as plastic resins, typically require larger sample sizes. The instrument is optimized for low moisture testing with a 30g load. Ashing typically requires a smaller sample size to reduce the residue that is emitted during testing. The instrument is optimized for ashing with a 4g load. Contact your technical sales representative for appropriate sample sizes.
Sample Window - The number entered sets the allowable tolerance of the sample to be loaded.
