The % value will flash while this screen is displayed. Each time the “DOWN”
pushbutton is depressed, the setpoint will be decreased by 0.1%. If the
“UP” pushbutton had been chosen, the value would be increased by 0.1%
each time the pushbutton was depressed.
The operation of the “HI” setpoint is exactly the same as for the “LO”. Re-
member the “Oxygen LOW ALARM SETPOINT” is adjustable in increments
of 0.1% from 0% to 21.0%, and the “Oxygen HIGH ALARM SETPOINT” is
adjustable in increments of 0.1% from 21.0% to 25.0%.
For all sensors, when the desired setpoint is reached, depress the “SET”
pushbutton. If the “SET” pushbutton is not depressed while in this screen,
after fifteen (15) seconds the unit will automatically revert back to the previ-
ous setpoint.
If the “SET” pushbutton is depressed, the “ALARM SETPOINT” screen will
reappear and display the new setpoints in one of the following screens:
