set if the detector is deactivated for more than
minutes.

Viewing Gas Exposu

as Exposure Description

A (toxic only)

Time-weighted average
(TWA) based on accumulated
exposure to toxic gases aver-
aged over a work day accord-
ing to OSHA or ACGIH
method.

EL (toxic only)

Short-term exposure limit
(STEL) to gas based on a
5-15 minute user selectable
period.

eak (MAX)
Peak (MAX) concentration
exposure during work shift.

r oxygen, it is the highest or the lowest concentration
countered.

Press and hold C until t
peak (MAX) gas exposu
displays.

The TWA gas exposures
display next.

The STEL gas exposure
display last.
