ADVANCED SETTINGS BUTTON

The 

Advanced Settings 

button (marked as

 5.3

 in 

Figure 3-3

) opens a dialog box 

(

Figure 3-6

) where the PID values can be adjusted. This relates only to the target RPM 

adjustment algorithm implemented in software for the demo application example. It is 
used for the Auto and Constant Demo modes as the RPM value must adjust in order 
to either reach the target temperature established as a parameter in the two modes, or 
keep it constant, depending on which mode is used.
