Computrac MAX-1000 User's Manual - Arizona Instrument

1 INTRODUCTIONThe Arizona Instrument MAX-1000 is a high performance moisture analyzer. It usesthe proven loss-on-drying method to detect the volatile content of a sample of testmaterial. The instrument uses Arizona Instrument's pioneering prediction method ofautomatically ending a test to provide accurate results in the shortest possible time.Caution:The MAX-1000 uses a delicate and very sensitive force balance toweigh samples and record very small weight losses. The balance is capableof measuring weight to a resolution of 1 milligram, over a sample weightrange from 1 gram to 40 grams. Careful handling is necessary to preventdamage to the balance. With proper care, the instrument will provide years ofdependable service.Typically, the instrument result is precise to better than:2.0% CV (coefficient of variation) from 0.100% - 100%It will test at temperatures from room temperature to 225 o C, controlled to a precisionof plus or minus one degree. The advanced heat control program brings the sample upto temperature in less than three minutes. Depending on the rate of volatilization ofthe sample moisture, test results are available in as little as two minutes, twice as fastas older instruments of this type.The instrument is programmable through the simple to understand front panel menusystem. For plant control purposes, the programming features can be placed underaccess code control, preventing unwanted changes to operating parameters. Advancedcomputer circuitry enables the instrument to store test parameters for 5 differentmaterials. Test data can be printed and may also include graphical representations ofthe drying process. Test data is stored and can be sent directly to a personalcomputer.The MAX-1000 printer output is compatible with the Centronics parallel printerinterface, widely used as the standard personal computer printer format.1
