• 15:30 UTC disconnected from the line
• flow measured ambient condition 17 lpm 
• cleaned from insects inside the chamber 
• flow unstable varying form the correct one 17 lpm to 2 lpm periodically
• 07:55 8-11-2024 UTC reconnected to the line 
• acquisition issue (some of the settings lost by switching off were not reset correctly, check)

13:47 UTC Kalman filter turned off

• 13:22 UTC Disconnected from the line and turned off 
• Cleaning of insect trap and optical chamber
• optical calibration (acceptable)
• flow calibration, flow measured after calibration 4.980 lpm in STP (stp factor used 0.74)
• 13:50 UTC reconnected to the line

• 07:52 UTC Test with kalman filter off  
• 12:00-13:07 UTC zero with kalman filter off (results reported in table attached)

• 7:00 UTC disconnected from inlet
• Measured flow 6.987 lpm (23°C, 78700 Pa)
• Chamber cleaning
• Span check
• Zero check
• Full calibration + zero adjust
• 10:37 UTC reconnected to inlet

Disconnected from the line 08:40 UTC.

Reconnected 09:35 UTC.

• Disconnected from the line 08:41 UTC.
• Cleaning of the optical chamber.
• Flow calibration.
• Leakage test at 5 lpm. Result 0% flow difference. Acceptable.
• Stability test. Acceptable.
• Clean air test. Acceptable.

• Reconnected to the line 15:00 UTC. 

At 9:30 the instrument has been disconnencted from the inlet to be taken to Leipzig for intercomparison. The chamber was cleaned after disconnenction. 

Calibration performed and zero check  after calibration

Flow calibration and resetting pressure 790 hPa

At 15 pm (UTC+2) the time interval between one zero and the other have been modified from 3 hours to two hours, the duration of the zeros from 20 minutes to 10 minutes.
