Important Notice

This instrument provides measurement readings to its user, and serves as a tool by which
valuable data can be gathered. The information provided by the instrument may assist the user
in eliminating potential hazards caused by his process; however, it is essential that all
personnel involved in the use of the instrument or its interface, with the process being
measured, be properly trained in the process itself, as well as all instrumentation related to it.

The safety of personnel is ultimately the responsibility of those who control process
conditions. While this instrument may be able to provide early warning of imminent
danger, it has no control over process conditions, and it can be misused. In particular, any
alarm or control systems installed must be tested and understood, both as to how they
operate and as to how they can be defeated. Any safeguards required such as locks, labels,
or redundancy, must be provided by the user or specifically requested of TI/AI at the time
the order is placed.

Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser
is responsible for the training of personnel, for providing hazard warning methods and
instrumentation per the appropriate standards, and for ensuring that hazard warning devices
and instrumentation are maintained and operated properly.

Teledyne Instruments/ Analytical Instruments, the manufacturer of this instrument, cannot
accept responsibility for conditions beyond its knowledge and control. No statement
expressed or implied by this document or any information disseminated by the
manufacturer or its agents, is to be construed as a warranty of adequate safety control under

3.1. Unpacking and Initial Setup

CAUTION: TO AVOID PERSONAL INJURY, ALWAYS USE TWO

PERSONS TO LIFT AND CARRY THE MODEL
6400EH.

1. Inspect the received packages for external shipping damage. If

damaged, please advise the shipper first, then TAI.

2. Included with your analyzer is a printed record of the final

performance characterization performed on your instrument at
the factory. This record is an important quality assurance and
calibration record for this instrument. It should be placed in the
quality records file for this instrument.

3. Carefully remove the top cover of the analyzer and check for

internal shipping damage.

 Remove the set screw located in the top, center of the rear

panel

 Remove the screws fastening the top cover to the unit (four

per side).

 Lift the cover straight up.

Note: Printed circuit assemblies (PCAs) are sensitive to electro-

static discharges too small to be felt by the human nervous
system. Failure to use ESD protection when working with
electronic assemblies will void the instrument warranty.

See Chapter 12 of the 6400E Manual (P/N 04515) for more
information on preventing ESD damage.

Zero Air

On Units with zero/span valve option installed, this port connects the zero air gas or the
zero air cartridge to the analyzer.

FUNCTION

Figure 3-5 of the 6400E Manual shows the internal pneumatic flow
of the 6400E in its standard configuration. For a diagram of the internal
pneumatic flow of the 6400EH, see Figure 3-2 of this manual.

3.2.2.1 PNEUMATIC CONNECTIONS TO 6400EH BASIC CONFIGURATION

The pneumatic connections for the 6400EH analyzer in its basic
configuration are nearly identical to those described the 6400E Manual
in Section 3.1.2.2 except that the 6400EH has an external pump.
Therefore:

 A pneumatic line of ¼” PTEF must be attached between the

analyzer’s exhaust port and the inlet port of the pump.

 The exhaust from must be vented outside the shelter or immediate

area surrounding the instrument using a maximum of 10 meters of
1/4” PTFE tubing.

3.3 Initial Operation

With the following exceptions, the operation of the 6400EH is
nearly identical to that of the 6400E. Please refer to the 6400E User’s
Manual, Chapter 3, for details on initial operation, including common
warning messages, functional checkout of the instrument, initial
calibration and common interferents for the 6400EH.

3.3.1 Warning Messages

Please refer to the 6400E User’s Manual, Chapter 3, for a complete
listing of warnings for the 6400EH. The following table lists warnings
that differ in the 6400EH from those described in the 6400E manual.

Table 3-2: Possible Warning Messages at Start-Up

MESSAGE MEANING

Vacuum Pressure Warning

The vacuum pressure reading is out of it’s allowed range. The pump
may have failed, or the instrument may have a leak or obstruction in
the flow path.

3.3.2 Test Functions

Check to make sure that the analyzer is functioning within
allowable operating parameters As described in Section 3.2.4 of the
6400E Manual (P/N 04515). The available test functions for the 6400EH
is shown in Figure 3-5.

3.3.3 Interferents for SO

2 Measurements

Hydrocarbons are a significant interferent for UV fluorescent SO2
measurements, however, the typical 6400EH application does not have
hydrocarbons in the sample stream. Therefore, in order to reduce cost to
the customer, the 6400EH in its standard configuration does not include
a hydrocarbon kicker/scrubber.

If your application includes hydrocarbons in the sample gas stream,
it is very important that they be removed from the sample gas prior to
them entering the analyzer’s sample chamber. A hydrocarbon Kicker
Option (OPT 65) package (see Section 5 below) is available for this
purpose.

UV Fluorescence SO2 Analyzer FAQ

Frequently Asked Questions

Q: How long does the sample pump last?
A: The sample pump should last about one year and the pump

diaphragms should to be replaced annually or when
necessary.

To determine if the diaphragm on a 6400EH needs replacing check

the VAC test function (instead of the PRES function as described in the
6400E Manual). If the VAC value is > 10 in-Hg-A, the diaphragm should

be replaced.
