a Warning
To avoid possible personal injury, do not turn off
the detector during a workshift. The detector
automatically resets the TWA and maximum gas
exposures at startup. If you restart the detector
during a workshift, these values will not reflect
the entire workshift.

Time-weighted average based on

value.
Maximum*
(Peak)
For each gas level further from
the acceptable range, the
detector resets the maximum gas
exposure to the new level.
* Maximum gas exposure describes both very high and
very low levels of oxygen.
