this manual, MAX
®
4000 is used to refer to both the MAX
®
4000 and the MAX

5.3. Oven
The sample oven is designed to remove volatile components from the sample as quickly
as possible, while maintaining accurate temperature control to prevent sample
degradation. Oven temperature is measured with a Resistance Temperature Device
(RTD), mounted in a rugged metal tube to prevent damage and dislocation. Temperature
control accuracy is within one degree of the set value after equilibrium is reached, and the
700-watt heater reaches equilibrium in 90 to 180 seconds, depending on the difference
between the starting and setpoint temperatures. Closed loop feedback control assures
a constant temperature even if power line voltage varies during the test. After a test is
completed, the heating system is turned off and the lid cooling fan is turned on. If
desired, open the lid after testing to speed cooling before performing the next test.
