Processing Record for this file: (Make notes here unique for this file) Loading 6/1 - 7/1/2014 Data loaded from detarred, dezipped and renamed files from the DMF To reduce Operator need for frequent filter changes, dilution turned on @ 14-02-21 21:12. Every 24-h, the dilution is turned off for 5 minutes. This was not long enough to get an undiluted sample. As always, data not reported for T(blue) < 0.7 Impactor in place. HOWEVER, signal wired backwards until 2014-06-19 20:00. The 10 and 1 in the primary data files (on the master\impactor) are reversed. As cofirmation, the flow signal decreases slightly when the impactor is in the 1-um state. The data polarity problem was corrected in software (leading to the correct polarity signal being recorded) on 2014-06-19 20:00:28. For this month, the problem was corrected here in the Mentor QA/QC'd data files using: root:psap_out:impactor[0,1627228] = root:inputfolder:wave11==10 ? 1 : (root:inputfolder:wave11==1 ? 10 : root:inputfolder:wave11) and the following notation put in Comment 1: DQR D140703.2 Impactor polarity reversed in raw file until 2014-06-19 20:00:28. Corrected here. Dilution operational at ~0.5. Some evidence of supermicron particles. A number of local events resulting in high absorbance. These were not edited.
