Alarm Set Points
This menu option allows you to set your alarm limits. Whether these limits
represent high or low alarms is defined using the Alarm Configure menu
option, although certain restrictions apply (See the "Alarm Configure" sec-
tion later in this chapter for further help on defining high/low alarms).
Also note that oxygen and combustibles alarms are disabled during calibra-
tion cycles.
If an alarm triggers, an up or down arrow (depending on whether a high
or low alarm) will appear to the right of the process reading on the display.
