2.4 Inputs – Intrusive and Non-Intrusive
The gas monitor can be configured using intrusive and non-intrusive means. Both methods
of configuration are accomplished through physical inputs that are visible behind the glass panel
of the gas monitor.
A set of four keys are used when intrusive programming is appropriate (i.e., when the enclosure
can be removed and when the keys can be manually pressed). These keys are the mode,
increment (+), decrement (-), and enter keys. Refer to
