High
Concentration
Message
When the “High concentration message” is
displayed, it means that the PortaCount Fit
Tester detects ambient concentration levels
higher than recommended. Prolonged exposure
to excessive concentration levels could degrade
the performance of the PortaCount Fit Tester over
time, resulting in failed daily checks or a “Low
Particle” message. This message does not
necessarily mean that the PortaCount Fit Tester
will stop working soon. Fit test results are
accurate even when this message is displayed.
Refer to the Troubleshooting chapter for other
possible causes and solutions for this message.
Low Alcohol
Level Message
When the "Low Alcohol Level" message is
displayed, it means that the PortaCount Fit Tester
may be low on alcohol. This message does not
necessarily mean that the PortaCount Fit Tester
will stop working soon. Fit test results are
accurate even when this message is on. Refer to
the Troubleshooting chapter for other possible
causes and solutions for this message.
Shipping & Storage Precautions
When transporting or storing the PortaCount Respirator Fit Tester, it is
important to remove all alcohol. Transporting or storing the
PortaCount Fit Tester with the alcohol cartridge inside may cause
flooding of the optics.
When putting the PortaCount Fit Tester back into the carrying case,
follow the steps outlined below:
1. Remove the alcohol cartridge from the PortaCount Fit Tester and
store it in the alcohol fill capsule. The alcohol fill capsule is
designed to be a safe transportation and storage container for
alcohol. The alcohol cartridge can be left soaking in alcohol
indefinitely.
2. Cover the cartridge cavity with the storage cap. Installing the
storage cap into the cartridge cavity prevents dirt or debris from
getting inside the PortaCount Fit Tester.
