(7) Perform cleaning for about 5 minutes.
* The required time for cleaning varies depending on the usage environment.

* To shorten the cleaning time as much as possible, perform a cleaning following the above procedure
right after measuring and especially after measuring in a highly concentrated environment (100 CPM
or higher) or after performing a long-term continuous measurement.
>>> If you leave the instrument without cleaning, the remaining dust will become deposited inside the
optical system, which can deteriorate the measurement accuracy and may affect accurate
calibration.
* Perform cleaning in a clean atmosphere.
If you perform a cleaning in a dirty environment, it can cause discrepancies. Therefore, make sure to
perform a cleaning in a clean environment.
