Aerosol production without filter – second measurement
1.
Wait 10 minutes.
2.
Read the parameter
raw(600 s)
and write it down (value 2 for calcu-
lation of
C
m,Promo
).
3.
Calculate an average of the values 1 and 2. This average is used in the
calculation formula 1 as
C
m,Promo
.
Calculating and saving the factor for mass concentration
1.
Apply calculation formula 2 to determine th mass concentration
C
m,grav
.
2.
Use
C
m,grav
and C
m,Promo
to calculate the factor for the mass concentra-
tion
(calculation formula 1)
.
3.
Set the flow rates
main air flow sp
and
generator flow sp
to zero.
4.
Close the software
PMFT1000
.
5.
Open the file
PMFT1000_Flow.ini
and enter the factor in the section
FACTOR_MASS as the value for SALT or OIL.
6.
Save the file and close it.
