o the time interval at which the Aethalometer advances tape (hours) – TA INT or,
o the time at which the Aethalometer advances tape – TA Time.
o Time & Date: adjusts current local time.
o Time zone and DST: Instrument default value is UTC (no DST), Changing time
zone or DST doesn't change local time. When DST if enabled occurs instrument
is stopped (if running) then time is synced. After that instrument returns back
to the operation state it was before clock change.
ADVANCED with all parameters which can be set in the Aethalometer.
o ATNf1 – low point of compensation algorithm
o ATNf2 – high point of compensation algorithm
o Z – compensation algorithm parameter
o C – compensation algorithm parameter
o Kmax – maximum value of the compensation coefficient
o Kmin – minimum value of the compensation coefficient
o Aff – Ångström exponents for fossil fuel
o Abb – Ångström exponents for wood burning
o Warmup interval – time in minutes after tape advance for clean air pass trough
o TA adjust – fine adjustment of the tape advance (- 50 to 50 %)
o External ID – remote protocols instrument identification number (1 – 255)
LOG with the last operational reports of status, parameter changes, data download.
MANUAL with basic commands, to operate hardware (solenoids, pump, chamber,
TA)
DATA with two sub-tabs: TABLE and EXPORT.
TABLE where raw measurement values are reported, BC concentration calculated
from each individual spot (BC1, BC2), and the compensated BC concentration. All
three concentrations have the unit ng/m
3
.
EXPORT with selection data to be copied to USB
SYSTEM RESTORE allows for restoration of the old setup file with all instrument
settings. You can select a setup file with a date & time in the name.
DATA IMPORT allows for importing data from the thumb drive. The data has to be
in the same folder and format as it is when exported to the thumb drive.
