3.1.1.4. Connecting the Serial Ports
If you wish to utilize either of the analyzer’s two serial interfaces, refer to Section 6.9 of
this manual for instructions on configuration and usage.
3.1.2.
Pneumatic Connections:
CAUTION
To prevent dust from getting into the analyzer, it was shipped with small plugs
inserted into each of the pneumatic fittings on the rear panel. Make sure that
all dust plugs are removed before attaching exhaust and supply gas lines.
Sample and calibration gases should only come into contact with PTFE (Teflon) or glass
or materials. They should not come in contact with FEP or stainless steel materials.
Figures 3-6 and 3-7 illustrate the most common configurations for gas supply and
exhaust lines to the Model 100E Analyzer.
Please refer to Figure 3-2 for pneumatic connections at the rear panel and Table 3-4 for
nomenclature.

FUNCTION
Sample
Connects the sample gas to the analyzer. When operating the
analyzer without zero span option, this is also the inlet for any
calibration gases.
Exhaust
Connects the exhaust of the analyzer with the external vacuum
pump.
Zero Air
On Units with zero/span valve or IZS option installed, this port
connects the zero air gas or the zero air cartridge to the analyzer.
Attach the 1/4" exhaust line to the exhaust port of the analyzer and to the inlet port of
the pump.
CAUTION
The exhaust from the external pump needs to be vented outside the
immediate area or shelter surrounding the instrument and conform
to all safety requirements using a maximum of 10 meters of 1/4”
PTFE tubing.
Attach the sample line to the sample inlet port. Ideally, the pressure of the sample gas
should be equal to ambient atmospheric pressure.
