Low Alarm Setpoint
The Low Alarm Setpoint display is used to set the threshold for the low alarm. For
an oxygen sensor, this threshold indicates the depletion oxygen concentration at
which the alarm will be activated.
On entering this screen, the display will
show the present threshold value. All
characters of the primary display will
blink to indicate that they are ready to
change. The threshold is incremented
by pressing the Enter button. Simple
momentary presses will increment the
value by 1 unit. Holding the Enter
button for an extended time will
increment the value much faster.
Low Alarm Setpoint Screen
Upon reaching the maximum value (which is sensor dependent), the display will
roll over. Pressing the Mode button from this display causes a transfer to the High
Alarm Setpoint screen.
