•
atm. pressure: displays the actual absolute barometric pressure
•
gas pres. OK: green indicator displays that C3H8 and N2 gas pressure is OK
•
air pres. OK: green indicator displays that oxidation and quench air pressure is
OK
•
shutoff valves: green indicator is lit when all shutoff valves are open
•
C3H8 concentration too high: red indicator is lit if the fuel gas (C3H8)
concentration is above normal level

the lower part provides information about the aerosol output parameters:
•
actual aerosol output: displays the actual aerosol output flow of the burner. The
flow is measured in lN/min (slpm), meaning the gas flow at 0 °C and 1013 mbar.
•
back pres. too high: red indicator is lit if the back pressure (pressure inside the
burner) is above 500 mbar.
•
back pressure: displays the actual back pressure, measured in mbar
•
run: green indicator shows that soot is being emitted
•
flame: yellow indicator displays that the flame is being detected
•
aerosol temperature: displays the actual aerosol temperature, measured in °C
Note:
The aerosol output temperature is measured at the burner outlet. The aerosol
temperature may decrease if the aerosol is lead through the test stand tubing. If
you need to know the accurate aerosol temperature at the entrance point of your
DUT (e.g. filter), install a separate temperature sensor in a appropriate position.
