Calibration of volume flow rate

To calibrate the volume flow rate, the aerosol inlet has to be connected to an
external volume flow meter. Recommended meter: Gilibrator-2, Sensidyne.

The volume flow rate of the device is regulated to 1.0 l/min. A correction
value can be adjusted with the keys + and - for calibration purposes. Change
the correction value such that the volume flow rate 

Flow

 shown on the

device is the same as the value measured by the external volume flow
meter.

Important: For correct calibration, the volume flow rate has to be as steady
as possible before and during measurement. Always avoid an erratic volume
flow rate course.

Connecting aerosol inlet tube to measuring device

On the model without weatherproof housing, the aerosol inlet tube is
accessible when the sampling head is unscrewed.
