6.2 Vanes and hot wire
In the “channels” menu :
➢ Select with arrow key the sub-menu “Airflow” then press OK.
➢ Select “Channel num.” and press OK.
➢ Select a channel number and press OK.
➢ Go to the line “Type” then press OK.
➢ Select the required type : “Rect”, “Circ” or “K factor” and press OK*.
If the type is Rect or Circ :
➢ Go to “Rect” or “Circ”, press OK, select its size then press OK to validate.
➢ Go to the line “Areas” then press OK.
It is possible to change units and size.
➢ Select “Unit” with the arrow keys then press OK. Select mm or in and press OK.
➢ To modify areas, select with arrow keys “Rect.” or “Circ.” and press OK.
➢ Select the size to modify in the list and press OK.
➢ Set the size with arrow keys between 1 and 2500 mm then press OK.
➢ For a K factor : go to “K factor”, press OK, select the K factor then press OK to validate.
➢ If the airflow is calculated with a pressure module, then go to “d/p elem.” to select the differential pressure
element. Press OK then select the element between “Pitot L” (coefficient : 1.0015), “Pitot S” (coefficient : 0.84),
“Débimo” (coefficient : 0.8165) and “Other”. If “Other” is selected, then enter its differential pressure coefficient
between 0 and 9.9999.
➢ Go to the line “K2 fact.” and press OK to select or unselect the K2 factor.
