Please use computer time!!!

23:30 entered the CAF station

0:28 CPC shows about particle concentration 4e3/ccm inside CAF

Measured before cleaning 
short DMA: pid controler shows sheath 10.0 lit/min, 7.4 %
CPC flow: 1.034 l/min STD!!!
sheat flow: 10.17 l/min
aerosol flow: 1.00 l/min, +/-10% fluctuating with sheath flow blower regulation, OK-ish

long DMA: pid controler shows sheath 10.0 lit/min, 5.6 %
CPC flow: 0.967 l/min
sheat flow: 10.01 l/min
aerosol flow: 1.008 l/min

APS: looks broken, after restart started to work normaly
Total flow 5.0 l/min

01:05 start cleaning APS
1)Filters needed have not found them!!!
2)Paper for cleaning is missing!! going to use toalet paper.
3)TSI flow meter disapeared

APS:
Total flow 5.0 l/min
Sample flow 0.95 l/min
Filters change necesary next visit, bit black.

DMPS:
both DMAs cleaned, butanol bottles disconected, tomorrow cleaning of CPC.

Full maintenance of pump, pump was fl of paper from aethalometer from last winter, cleaned,
membranes changed however they are still in good condition.

Heating tape on inlet changed, testing through the night.

13.9.2011
00:00 arival of FMI personel (DB, TL) and Vova

CPCs dried over night, maintanance of CPCs, butanol and water removal filters changed, flow 1.001 l/min, no other changes made to shortDMA CPC.
Short DMA flows:
CPC flow: 1.002 l/min
Aerosol flow: 1.01 l/min
Sheath flow: 10.15 l/min
Voltage checked OK

Long DMA flows:
CPC flow: 0.98 l/min
Aerosol flow: 0.96 l/min
Sheath flow: 10.02 l/min

I have tried to repare broken pump, membranes were changed, it works but makes terible sound, probably bearings are out. This has label broken
and can be sed only in emergency situations, and better for outdoor produces quite a lot of dust.

06:54 MOXA-8port installed in PC, now we have 10 serial ports together.

09:00 APS com port changed to MOXA also, there seem to be communication trouble on COM1 port. It produces mess in APS data
and terribly high concentrations <.523 microns about 2 000 000 /ccm!!! also some extra lines in logged data

15.9. 2011
1:00 FMI (DB and TL) and NOAA (Rob) personel arrival
1:15 Aethalometer conected to FMI PC data stored to C:\Data together with other instruments.
1:34 Calibration of Aethalometer, should be 4.9 l/min, TSI mass flow controler shows 5.2 l/min STD, after calibration TSI 4.75 l/min STD
2:00 Aethalometer connected back to line.

aps - the main problem was laser hitting the nozzle in the detector chamber.
there was to big pressure to inlet which pushed the nozzle to the path of laser that made terrible
overcount due to reflection, inlet pushed up aps showes okish numbers.
