Lower Zero Dead
Band
The gas concentration within the dead
band limit will be suppressed to default
base concentration. i.e. if the gas
concentration is between the (default base
concentration lower dead band) and
(default base concent upper dead
band), then the reading will be the default
base concentration.

parameter is used to generate over-range
warning.

Oxygen needs just span
calibration. No zero
calibration required.
