6.7 Flow verification

Flow verification routine is used to check if internal flow-meters need calibration. No
instrument settings are changed during the flow verification routine.
For flow verification you need a flow calibration pad and an external flow-meter, which you
connect to the Aethalometer inlet.
To start flow verification select "Flow verification" button on Operation/General screen. When
the procedure is finished you will get the table with measured flows, reported at the flow
reporting standard selected for the instrument. Flow verification report:
