MAO/SMPS/S1 - Instrument maintenance
A number of instrument maintenance tasks were performed. The flow rate of the system from the impactor was tested. Inlet flow rates and nozzle pressures were examined on the CPC 3772. The accuracy of the classifier voltage and sheath flow rates were evaluated. A HEPA filter zero test was performed. During an approximately 24 hour period, the voltage cable was left unplugged from the classifier.
The data during the periods specified should not be used.
