Alarm contents
It is reported when purge pressure
lower than the value set as alarms
on the "AO Select" screen.
It is reported when "Analog Output
/ Alarm Record" is set to "Over
H-Limit 1" or "Over H/L Limit 1"
on the "Alarm Setting" screen, and
the measured value exceeds the
limit alarm of Range 1.
It is reported when "Analog Output
/ Alarm Record" is set to "Under
L-Limit 1" or "Over H/L Limit 1"
on the "Alarm Setting" screen, and
the measured value is less than the
limit alarm of Range 1.
It is reported when "Analog Output
/ Alarm Record" is set to "Over
L-Limit 2" or "Over H/L Limit 2"
on the "Alarm Setting" screen, and
the measured value exceeds the
limit alarm of Range 2.
It is reported when "Analog Output
/ Alarm Record" is set to "Under
L-Limit 2" or "Over H/L Limit 2"
on the "Alarm Setting" screen, and
the measured value is less than the
limit alarm of Range 2.

setting or the analyzer is not purged.
