Hot-wire probe corrective coefficient setting.

The velocity probe consists of a wire heated at a temperature 

higher than the ambient temperature.

Over time and depending on the using conditions, it can be 

altered (like a light-bulb filament) and can lose accuracy. To 

solve this problem, a corrective coefficient can compensate 

the probe deterioration.

It can be modified by the installer.

To do so, proceed as follows : enter the menu as explained in 

part 4.4.1.

Once in the menu, enter the sub-menu “probe calibration” by 

pressing the button “ENTER”.
