Powering On And Warming Up; Powering Off; Factory Reset - Nuvair Pro O2 alarm Analyzer Operation Manual

6.0 Powering on and warming up

Press the On/Off button for more than one second, until the display shows "on", after
that the "Att" (wait) message will be displayed for about 4 seconds, then the sensor auto-
calibration lasts about 5 seconds; during this time the display will show the messages "CAL"
and "Att" alternatively.
Be sure that during this time the sensor is exposed to the gas mix with the oxygen
percentage as programmed in the "O2c" parameter (see programming procedure). By default
the parameter is set at 21% by default that corresponds to the percentage of oxygen in free
air, be sure that the air flow at this time across the sensor is 21% oxygen before turning on
the analyzer.
During the warm up time if the oxygen percentage of the gas flowing across the sensor
is a different value of calibration set in the instrument, a failed calibration is obtained
and the wrong gas percentage will be displayed. Wrong oxygen analysis may lead to
death.

6.1 Powering Off

At the home or gas reading screen, hold down the On/Off button for a couple of
seconds. The Analyzer will display "OFF" and then go blank.

7.0 Factory Reset

In case it is necessary to reset the Pro O
power on the Analyzer pressing at the same time for more than one second the
"On/Off" and "Adjust" buttons. On the display will appear "res" and the instrument will
go to the reading page.
In case of reset, the instrument will delete all the alarms settings, the full scale value,
and any new conversion value of Oxygen sensor will be reset to factory settings.
Before using again the instrument, it may be necessary to program again the alarm
values, the full scale value, and the Oxygen sensor calibration if changed. All the
analysis concentration shown on the display would be wrong. Wrong Oxygen analysis
may lead to death.
