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.
