Calibrating particle size and particle velocity
Prerequisites
• Calibration mode is activated.
• The device has been tested for leakage and verified.
• The device’s zero point has been checked.
• The aerosol sensor offset has been set.
• The flow rate has been calibrated.
• Once / upon initial startup:
The average particle velocity has been set.
Calibration dust MonoDust 1500
MonoDust
1500
A special dust with a very small monodisperse distribution and known parti-
cle size is used to calibrate the device. Delivery of the device includes one
container of the calibration dust
MonoDust 1500
. Use only
MonoDust 1500
to calibrate the device.
When used properly, a single container is sufficient to calibrate the device
multiple times. Only a small amount of the dust is needed for the calibration
process.
MonoDust 1500
can be ordered from Palas or your sales partner.
The label on the container as well as the certificate for the calibration dust in-
dicate reference values (
setpoint raw channel
) needed to calibrate the
particle size.
