Selecting a Fit Testing Location
To obtain valid results using the N95-Companion with the P
ORTA
C
OUNT
Plus for fit testing, you must conduct the fit tests in a suitable location while
running the supplied Model 8026 Particle Generator.
The N95-Companion uses a small portion of the room aerosol for fit testing.
To obtain consistent and repeatable fit tests, TSI recommends that you
operate the particle generator to supplement the naturally occurring room
aerosol. For the generator to function properly, you must conduct the fit tests
in an enclosed area. A medium-sized room is normally a suitable location.
The particle generator does not function efficiently in an open area or a very
large room.
