Calibrating particle size and particle velocity

Prerequisites

• The device’s zero point has been checked.
• The calibration menu is open.

Calibration interval

We recommend calibrating the aerosol sensor every week.

Administering calibration dust

Connect a hose to the aerosol inlet of the aerosol sensor.

Hold the hose in the container of

MonoDust 1500

Gently squeeze the container several times to exchange some air be-
tween the container and the environment.
