Case purge option
The purge medium (e.g. to minimize CO
2
interference or for enhanced safety when
measuring corrosive or poisonous gases)
• must be dry, clean and free of corro-
sives or components containing sol-
vents.
• has to be free of components to be
measured, to minimize cross interfe-
rences.
Its temperature must correspond to the am-
bient temperature of the analyzer, but be at
least within the range 20…35 °C (68…95 °F).
For information about values for pressure and
ow, please contact your nearest EMERSON
Process Management sales ofce.
Open reference option
I
n some cases, the measuring cell has an open
reference side, to be supplied with nitrogen.
This nitrogen
• at least should be of quality 5.0, which
means nitrogen of purity ≥ 99.999 %.
If such gas is not available, the substitute
• must be dry, clean and free of corrosi-
ves or components containing solvents.
• has to be free of components to be
measured, to minimize cross interfe-
rences.
In any case, the gas temperature must cor-
respond to the ambient temperature of the
analyzer, but at least be within the range
20…35 °C (68…95 °F).
Pressure and gas ow must remain within
the values given in the „Measurement
Specications“ section within this manual.
Perform a calibration each time
the source of this gas (e. g.
bottle) has changed!
