Introduction
Safety & Environmental
The instrument and related documentation must be reviewed for familiarization with safety
markings and instructions before operating the instrument.
Environmental Conditions - The QuantiFit2 is for use at an altitude up to 2,000m (6,500 ft.) with
a temperature range of 5 to 40 degrees C, maximum relative humidity of 80% non-condensing
and pollution degree 2.
Any use of the QuantiFit2 that is not outlined in this manual may invalidate the protection of
the instrument.
The QuantiFit2 comes with an external power supply that must be used for powering the
instrument when not using the optional battery pack. If the power supply becomes faulty or
damaged, it must be replaced. A power supply with the ratings listed in the
Specifications
Appendix must be used (100-240VAC, 50/60 Hz, 1A Max).
Under abnormal conditions, such as static discharge, it may be necessary to cycle power to
achieve proper operation.
Caution - The CAUTION symbol denotes a hazard. It calls attention to a procedure,
practice, or the like, which, if not correctly performed or adhered to, could result in
damage to or destruction of part or all of the instrument or data. Do not proceed
beyond a CAUTION symbol until the indicated conditions are fully understood and met.
Cross Contamination
OHD takes the safety and health of our customers very seriously. With this in mind, we believe
it is important to address concerns about possible cross contamination during fit testing. The
risk of cross contamination resulting from the use of a QuantiFit2 is very minimal. Fit Testing
itself does not increase or decrease a person’s risk of exposure to any virus or illness. The real
threat is coming into close contact with an infected person no matter the location or activity.
The QuantiFit2 does not trap air in its system either before, during or after a fit test. The
QuantiFit2 does not push air into the mask. The QuantiFit2 pulls air away from the test subjects
mask and vents it out of the system. This means that the chances of contaminated air being in
the system are, at worst, no more likely than contaminated air being in the surrounding
environment. If an infected person were to be fit tested, there is no more risk of contaminated
air being trapped and subsequently released on a succeeding fit test than there is just by
walking into the fit test area.
The QuantiFit2 and accessories are subject to surface contamination like any item in the test
area. Before and after fit test steps, when the test subject is wearing a respirator, his or her
inhalation is coming through inlets in the OHD adapter kit and the vast majority of exhalation
should travel through the exhalation valve and out of the respirator. There are many potential
mask and adapter configurations. The chance could exist in a configuration that exhaled breath
