Gas Alarm conditions & Advice:
If the current gas concentration reading meets or exceeds either
alarm set points, the transmitter alarm function activates.
When the alarm condition no longer exists, the transmitter exits
alarm mode and enters normal mode operation.
The Oxygen Low and/or High gas alarm set points are user settable
for either enrichment and/or deficiency alarm as desired.
