Subject: | MAG/PSAP/M1 - Impactor state backwards |
DataStreams: | magaospsap3wM1.b1 |
Description: | Impactor was installed on 2012-07-12 but did not toggle until 2013-05-16 00:04:19 UTC. The impactor as delivered did not have limit switches indicating the impactor state. Only the command signal was available and is saved in the 'master' data stream. A programming error led to the command signal having reverse polarity (1 is actually 10 and 10 is actually 1-um cutoff) |
Suggestions: | Alternative methods for determining the impactor state: 1) Monitor the PSAP flow . The flow decreases slightly in the 1 um state 2) Monitor the nephelometer pressure. The pressure decreases slightly in the 1 um state |
