►
Advantages of Sample Feedback Control Mode are: direct monitoring and active control of sample
temperature and independence from room temperature variations. The disadvantage is that it requires
manual operation for correct placement of the fine gauge thermocouple in a Reference Well.

Fan Speed
The Heating Box has an internal flow sensor that allows regulating the speed of the Air being blown inside
the enclosure. An increased speed allows a quicker start-up and a more uniform thermal distribution inside the
enclosure, a low speed allows instead a smooth operation in applications particularly sensitive to vibrations.
You can set the Air Flow value by pressing on Fan Speed icon
(see Figure 18 a). Then you can change
the value in the range 35-100 m
3
/h (see Figure 18 b). Only when you use the H201-FILTER-BOX, the working range
of the Air Flow becomes 35-70 m
3
/h, see paragraph 8.2.1.3.

You can also activate the ‘Fast Heating’
button (see Figure 19), which enables a quick start-up every time
you turn on the system. The ‘Fast Heating’ accelerates the transient time.
