Number concentration: displays the particle number concentration over time in the 
graph panel

Diameter: displays the average particle diameter over time in the graph panel

LDSA: displays the lung-deposited surface area over time in the graph panel

Induction correction: Rapidly varying charge concentrations inside the instrument in-
duce a current on the diffusion stage. This leads to error in number and concentration 
measurement. The induced current can be deduced from the time derivative of the 

fi

 lter 

stage signal. If you turn on the induction correction, this computed induced current is 
subtracted from the diffusion stage signal. The induction correction leads to a higher 
noise level on the diffusion stage, and thus should only be used when necessary.
