readings too
low during test.
Test will end, or
abort unless
corrected quickly.
If error pops up prior to test, have the client take
five-six big deep breaths. This will force air to
accumulate in the mixing chamber and trigger the
90 second countdown to start.
If error pops up mid test, volume of air measured is
too low. May be due to a leak in the accessories.
Check for the following:
● Good seal around MetaBreatherMAX
mouthpiece
● Mask fits snuggly
● Y-Valve assembled correctly
