• Replace cover, and reapply power.
Once powered, the display will briefly show the symbol for the gas being
monitored, then a live display of the gas concentration. Each AirAware
utilizes electrochemical sensors that may require between 10 and 360 minutes
(gas dependent) or 12-16 hours for NH3 and HCl to stabilize when initially
activated. During this warm-up period, the unit may display concentrations of
gas and possibly alarm. Allow sufficient time for the instrument to stabilize
prior to proceeding.
