TSI Instruments Aerotrak 9303 User Manual

Operation 3-3
Warm - up T im e
An initial warm-up period of 15 minutes is recommended before sampling
with the Model 9303. The warm-up period allows time for the optics to
reach a steady-state temperature. This will result in more repeatable
results. Neglecting the warm-up time may result in an overestimation of
particle size (approximately 10 percent). Neglecting the warm-up time will
not have a significant effect on particle concentration; therefore, a zero
count can still be performed without waiting for the warm-up period.
