I reset the dust monitor counts alarm levels to reflect the US Fed 209E cleanroom standards, as defined in T1400024. For Clean-1000 (General room monitoring of LVEA and VEAs) 0.3 minor 2000, major 3000 0.5 minor 750, major 1000 For Clean-100 (Open chambers, cleanrooms with Class-A, etc.) 0.3 minor 250, major 300 0.5 minor 75, major 100 The dust monitor alarm have been set to these levels. I will monitor over the next couple of weeks to see if these levels need to be adjusted.
