6.Channel configuration
The channel configuration allows to modify the displaying of the measured parameters.
The instrument is on.
➢ With the arrow keys, go to “Measurement”.
➢ Press OK.
➢ Press the function key “Channels”.
The different functions of the probe are displayed.
IIt is possible from the “Channels” menu to add or delete some measurements.
➢ Press the function key “Delete” in order to delete the selected measurement.
➢ Press the function key “Add” to display the selected measurement.
➢ Press “Add” to add a measurement on the screen (the default measurement displayed on the screen are the
primary measurements).
It is possible from the “Channels” menu to choose the displaying order of the measurement on the screen.
➢ With arrow keys, select the measurement to modify and press OK.
➢ Go to the line “Channel num.” then press OK.
Select the channel number and press OK.
6.1 Pressure module
Airflow:
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.
*For a hotwire probe, K factor is not available. It is possible to select “Cone” in addition to “Rect” and “Circ” :
➢ To select “Cone”, go to the line “Cone” then press OK.
• Select the type of cone : K35, K75, K120 or K150 and press OK.
• Press “Measures” to display the measurements.
