3.4 After the measurement
[Cleaning of internals]
Internals of the instrument may be contaminated after measurement.
Please carry out the following cleaning procedure after finishing the measurement.
− The method of cleaning and storage−
Caution
If cleaning is continued in a high concentration environment, the dust will accumulate on the filter and clog
the filter. In such case, the error indication (F) may be displayed indicating an insufficient flow volume.
In addition, this may lead to abnormal count with unstable readings as the particles accumulated on the
filter will flow in the instrument by vibrations.
① Stop the measurement before cleaning
② Connect the filter to the air inlet at the top of the instrument, using the supplied tube.
＊ There is a possibility that the tube will be folded and inlet will be blocked when connecting
the tube to the inlet. Operation of the instrument in such a condition will overload the
vacuum pump and shorten the operating life.
③ Change UNIT to counts (CNT) and start the measurement
④ Finish the operation only after the confirmation that the count value gets stable and doesn’t
increase or decrease for more than 10 seconds.
⑤ Turn the power off and put the cap over the inlet
※
To prevent the contamination during storage, do not fail to cover the inlet by cap.
