Getting Started Model 400E Ozone Analyzer
Instruction Manual
32 P/N 04316 Rev: B
NOTE
Sample Gas pressure must equal ambient atmospheric
pressure.
In applications where the sample gas is received from a
pressurized manifold, a vent must be placed as shown to
equalize the sample gas with ambient atmospheric pressure
before it enters the analyzer.
This vent line must be:
q At least 0.2m long
q No more than 2m long
q Vented outside the shelter or immediate
area surrounding the instrument
If your analyzer is equiped with wither the Zero/Span Valve Option (Option 50) or
the Internal Zero/Span Option (IZS - Option 51), the pneumatic connections should
be made as follows:
