High Alarm Setpoint
The High Alarm Setpoint screen is used to set the threshold for the high alarm. For
an Oxygen sensor, this threshold indicates the enrichment oxygen concentration at
which the alarm is activated.
On entering this screen, the display
shows the present threshold value. All
characters of the display 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 increments
the value much faster.
High Alarm Setpoint Screen
Upon reaching the maximum value (which is sensor dependent), the display rolls
over to the minimum value. Pressing the Mode button from this display causes a
transfer to the Cal Gas Setpoint screen.
