Condensation Particle Counter (TSI 3772) [view]

Action: Maintenance
When doing the flow cal with lab air:

Set the CPC back up and reconfigured the plumbing so that the orifice pressure on the CPC will register OK. Connected up to the strong vacuum so that the orifice pressure reads OK (this is fine because the MFC is maintaining the flow actual flow).

When doing the flow cal with lab air:

  • gilibrator 1.001 LPM
  • set point 0.990 LPM (volumetric)

When doing the flow cal inline:

  • gilibrator 1.005 LPM
  • set point 1.000 LPM

The inline set point is really variable, but after an average of 10 tests, we& 39;ve decided to leave it as above.
