-====== CPC Instrument Log ======
-  * July 24, 2013.  Reinstalled in rack #2 after used in lab.  The Saturator Wick, o-rings and filters were all replaced.  There was a leak before replacement of the Saturator Wisk/O-rings, but no leak afterwards.  Also, zero air test (filter on inlet) had zero counts.  The Critical Orifice is stored in the Black CPC 3771 case in 425 lab.  Pictures of the CPC and location of the critical orifice are on the Department Gallery site.  Started using a Alicat Volumetric Flow meter with the CPC.  Outlet flow is 1.0 l/min but inlet flow is only 0.75.  Assume issue with the the large drop in pressure across the CPC.  The Nozzle is like getting plugged.  Sent email to TSI asked about getting spare Saturator Wick, o-rings and filters; and what to do about maybe cleaning the nozzle.
-  * October, 2012.  Reinstalled in rack #2 after used in lab.
-  * December 10th, 2012. Calibrated the flow on the CPC. 1 lpm was a setting of 0.92 on the flow rate. Altimeter setting at GFK during the test was 29.72. The Citation altimeter set to 29.92 was indicating 1010 ft.
