Your safety and the safety of others is very important. We have provided many important safety
messages in this manual. Please read these messages carefully.
A safety message alerts you to potential hazards that could hurt you or others. Each safety
message is associated with a safety alert symbol. These symbols are found in the manual and
inside the instrument. The definition of these symbols is described below:
GENERAL SAFETY HAZARD: Refer to the instructions for details on the
specific hazard.
CAUTION: Hot Surface Warning
CAUTION: Electrical Shock Hazard
TECHNICIAN SYMBOL: All operations marked with this symbol are to
be performed by qualified maintenance personnel only.
CAUTION
The analyzer should only be used for the purpose and in the manner described in this
manual. If you use the analyzer in a manner other than that for which it was intended,
unpredictable behavior could ensue with possible hazardous consequences.

If you wish to utilize either of the analyzer’s two serial interfaces, refer to Section 6.10 and 6.12
of this manual for instructions on configuration and usage.
3.1.1.5. Connecting to a LAN or the Internet
If your unit has a Teledyne Analytical Instruments Ethernet card (Option 63), plug one end of the
7’ CAT5 cable supplied with the option into the appropriate place on the back of the analyzer (see
Figure 5-6 in Section 5.6.3) and the other end into any nearby Ethernet access port.
3.1.1.6. Connecting to a LAN or the Internet
If your unit has a Teledyne Analytical Instruments RS-232 multidrop card (Option 62), see
section 10.6.7 fo instructions on setting it up.
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 materials.
They should not come in contact with FEP or stainless steel materials.
Figures 3-6 and 3-7 show the most common configurations for gas supply and exhaust lines to the
Model 6200E Analyzer. Figure 3-8 shows the connections for units with valve options installed.
Please refer to Figure 3-2 for pneumatic connections at the rear panel and Table 3-4 for
nomenclature.

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.
2. Attach the sample line to the sample inlet port. Ideally, the pressure of the sample gas should
be equal to ambient atmospheric pressure.
28 M6200E Rev: A1
Model 6200E Instruction Manual Getting Started
NOTE
Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-Hg above
ambient pressure and ideally should equal ambient atmospheric pressure.
In applications where the sample gas is received from a pressurized manifold, a vent
must be provided to equalize the sample gas with ambient atmospheric pressure before
it enters the analyzer. The vented gas needs to be routed outside the immediate area or
shelter surrounding the instrument.
3. Attach zero air and span gas supply lines as appropriate (see Figures 3-6 & 3.7). For this type
of analyzer, zero air and span gas are defined as follows:
Zero air and span gas inlets should supply their respective gases in excess of the 700 cc
3
/min
demand of the analyzer. Supply and vent lines should be of sufficient length and diameter to
prevent back diffusion and pressure effects.

Some applications, such as EPA monitoring, require a multipoint calibration procedure
where span gases of different concentrations are needed. We recommend using a bottle of
calibrated H
S gas of higher concentration in conjunction with a gas dilution calibrator such
2
as a Teledyne Analytical Instruments Model 700. This type of calibrator precisely mixes a
high concentration gas from zero air (both supplied externally) to accurately produce span
gas of the correct concentration. Linearity profiles can be automated with this model and
run unattended over night.
