4.6 Adjusting the Impactor Position
The impactor may be set at three angles: 0
°, 45° and 90°. Turn the impactor to the desired angle.
(Note: The instrument has built in stops for each angle.)
4.7 Sampling Time
For instructions on how to set the sampling time, see Section 6. Settings Menu.
The initial setting of the sampling mode is 120s. Change the setting according to the dust
concentration of the environment to be measured. When performing measurements in a high
concentration environment, such as a work environment, select 24s. For indoor measurement in a
low concentration environment, select 120s. For measurements in a high concentration
environment, the cleaning frequency can be reduced by setting a short sampling time. For
measurements in a low concentration environment, the measurement accuracy can be increased by
extending the sampling time.
