combustible gas channels that have a unit of measure setting of %LEL. However, the Pioneer does
calculate and display TWA and STEL settings for combustible gas channels that have a unit of
measure setting of PPM/LEL.
The STEL reading represents a channel’s average gas readings for the past 15 minutes.
The TWA reading represents a channel’s average gas readings for the past 8 hours.
