5.3.4 Flow Calibration
The Flow Calibration is used for field audits or calibrations of the sample flow measurement.
Remove the TSP cap and any cyclones from the Aerocet-380 inlet tube, and then connect
the top of inlet tube to the outlet of a traceable flow meter using a length of appropriate
flexible tubing. The AEROCET-380 flow rate should be maintained to within ±0.1 LPM (1.9 to
2.1 LPM) for proper cut-point performance of inlet cyclones.

The Flow parameter is the current reading from the AEROCET-380 flow sensor, in actual
volumetric liters per minute. The AEROCET-380 should automatically regulate to the
setpoint (2.0 LPM) when the flow calibration screen is entered. This may take a moment.
The Reference parameter is where one can enter the correct value from your traceable flow
meter, using the scroll wheel.
The flow reading that you enter must be in actual
conditions
. The Flow value should change to match the Reference value when you select
the SET key.
