has an effect on instrument operation when an IR sensor is installed.
With
IR AUTO RANGE
set to
AUTO RANGE
(factory setting), the IR channel’s gas
reading will be displayed in %LEL until the gas level reaches 100 %LEL, or 5.0 %vol for
methane. Once the gas reading is above 100 %LEL, it is displayed in %vol. Alarm points
exist for the %LEL range but do not exist for the %vol range.
If

displayed in %LEL up to 100 %LEL.
