Instrument error contact output:
If an instrument error occurs,
an alarm is issued. The alarm is
assigned to a contact output.
Calibration error contact output:
If calibration is not performed
properly, an alarm is issued. The
alarm is assigned to a contact output

/P: Analyzer internal purge port:
For the following cases, /P should be
selected.
• When the sample gas contains combustible gas
•
When corrosive gases are present in the
atmosphere at the installation site.
• When the atmosphere at the installation site
contains the same gases as the measured
component.
Use dry N
2
or instrument air free of dust or
mist as the purge gas. The required flow
rate is approximately 1 L/min.
/A: CO Peak Alarm:
An alarm is issued when the number of
times the measured concentration of CO
peaks above the upper limit exceeds
the set value. The alarm is assigned to a
contact output.
