set alarm pressure min value
set alarm pressure max value
These commands set the pressure alarm minimum and maximum values to
value, where value is a floating-point number representing pressure alarm
limits in millimeters of mercury. The example that follows sets the pressure
alarm maximum value to 1000 mmHg.
Send: set alarm pressure max 1000
Receive: set alarm pressure max 1000 ok
alarm sample flow a min
alarm sample flow a max
alarm sample flow b min
alarm sample flow b max
These commands report the cell a and b sample flow alarm minimum and
maximum value current settings. The example that follows reports that the
sample flow alarm minimum value is 0.400 LPM.
Send: alarm sample flow min
Receive: alarm sample flow min 0.4 l/min
set alarm sample flow a min value
set alarm sample flow b max
value
set alarm sample flow a min value
set alarm sample flow b max value
These commands set the cell a or b sample flow alarm minimum and
maximum values to
value, where value is a floating-point number
representing sample flow alarm limits in liters per minute. The example that
follows sets the sample flow alarm maximum value to 1.400 LPM.
Send: set alarm sample flow max 1.4
Receive: set alarm sample flow max 1.4 ok
alarm trig conc o3
This command reports the O
3
concentration alarm trigger action for
minimum alarm, current setting, to either floor or ceiling. The example that
follows shows the O
3
concentration minimum alarm trigger to ceiling,
according to Table B-3 .
Send: alarm trig conc 03
Receive: alarm trig conc 03 1
set alarm trig conc o3 value
These commands set the O
3
concentration alarm minimum value, where
value is set to either floor or ceiling, according to Table B-3 . The example
that follows sets the O
3
concentration minimum alarm trigger to ceiling.
