Hardware
The MAX 5000XL consists of:
A ceramic convection air oven
A precision balance weighing mechanism with a resolution of 0.0001 gram and a
full scale range of 100 grams
A backlit, color graphic liquid crystal display
A microprocessor that controls the test process, data handling, communications,
and performs all necessary calculations, and
Connectors on the back panel for an Ethernet connection, parallel printer, and
serial communications devices (Other connections are provided that will be
implemented in later revisions to the instrument.)
implemented in later revisions to the instrument.)
The MAX 5000XL is designed to remain powered up at all times.
The balance requires a lengthy warm up period. The first test of the day can be made
sooner and with more accuracy if the unit remains powered over night. When not in use,
select a test with start temperature of 25º C and keep the lid down. The oven will remain
cool and the Liquid Crystal Display (LCD) backlight will turn off after a period of inactivity
to conserve energy. Press any key to restore illumination to the LCD.

If the test process is interrupted by outside interference such as static discharge, surges
or drops in line voltage, or otherwise freezes its operation and/or display, reset the
instrument by recycling power. By turning the instrument off and back on, the instrument
should return to normal operation. If the instrument does not return to normal operation,
contact AZI Customer Service at 800-528-7411, 602-470-1414, or by e-mail at

Oven
The ceramic sample oven maintains accurate temperature
control to prevent sample degradation as it removes volatile
components as quickly as possible. A Resistance Temperature
Device (RTD) mounted near the heater measures oven
temperature. Temperature is held within one or two degrees of
the set value (depending on the set value) after equilibrium is
reached. The oven usually reaches test temperature in 90 to 180
seconds, depending on the difference between the starting and
setpoint temperatures. The oven is automatically turned off
when the test is completed.

Due to the nature of the oven lining, the oven is cool almost
immediately after opening the lid. The sample will remain hot much
longer than the oven itself so caution is required when removing
used sample pans from the oven.
