When the PX5
®
is on speed 1, the ball will
float inside the flow meter. Ensure that it sits
above the curved line for the altitude and
temp for where the check is being performed.
Ex: 4,000ft above sea level and 70°F.
The flow meter levels are grouped by
temperature and altitude. Ex.: dashed box
shows levels for different temps at 0ft above
sea level. Choose the altitude closest to the
altitude where the check is being performed.

HOW TO READ THE FLOW METER LABEL.
Flow Meter Detailed instructions
Determine your location’s elevation and the current temperature. Note that these parameters
must represent the environment where the air flow check is being conducted, not the work
environment the unit is to be used in afterwards. If the environment changes after conducting the
air flow test, the unit will automatically adapt to any changes in air pressure or temperature.
Refer to an altimeter or lookup table to determine your location’s altitude. Refer to a thermometer
to find out the current temperature of your environment. Consult your supervisor if you are
uncertain about any of these parameters.
Check the green altitude indications to find the value closest to your location’s altitude. Check the
temperature markings vertically aligned with that altitude indication to find the one closest to the
temperature of your environment. This is the minimum flow rate marker to be checked to. Insert
the flow meter into the outlet of the PX5
® and rotate 1/2 turn to lock in place. Tilt the PX5 ® so
that the flow meter is vertical. Turn on the PX5
®
leaving it on Speed 1 and let the air stabilize over
a 30 second period. With the meter still in the vertical position check that the ball is sitting above
the minimum flow rate marker for your altitude and temperature.
Note that the Airflow Meter is labelled with altitude indications in meters as well as in feet.
Temperature indications are printed in °F as well as in °C. Make sure to read the Airflow Meter at
the proper units.
Do not use the PX5 ® if the meter does not reach the minimum airflow rate on the flow meter. Low
airflow will decrease the level of protection provided.
