SAFETY SUMMARY
If this equipment is used in a manner not specified in these instructions, protective systems may be
impaired.
AUTHORIZED PERSONNEL
To avoid explosion, loss of life, personal injury and damage to this equipment and on-site property,
all personnel authorized to install, operate and service the this equipment should be thoroughly
familiar with and strictly follow the instructions in this manual. SAVE THESE INSTRUCTIONS.
DANGER.
ELECTRICAL SHOCK HAZARD
Do not operate without doors and covers secure. Servicing requires access to live parts which can
cause death or serious injury. Refer servicing to qualified personnel. For safety and proper performance this instrument must be connected to a properly grounded three-wire source of power.
WARNING .
POSSIBLE EXPLOSION HAZARD
This equipment is used in the analysis of sample gases which may be flammable, and the burner
fuel used in the ionization process IS flammable. A system of intrinsically safe electronics and an
explosion proof tower are used to prevent any ignition of a flammable gas leak. For this to be effective, the module MUST be placed in a well-ventilated area, with unobstructed air flow around it.
DO NOT place it within another enclosure without assuring this ventilation.
DO NOT obstruct the vent holes on the top and sides of the module.
DO NOT place the FID module within another enclosure unless the latter has a guaranteed air circulation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Doing so will negate the safety features and may result in an explosion, serious injury, property damage and death.
WARNING .
FLAMMABLE SAMPLES
Consult the factory if flammable samples will be measured.
P-2 Preface Rosemount Analytical Inc. A Division of Emerson Process Management
Model NGA2000 FID2
Tampering or unauthorized substitution of components may adversely affect safety of this product.
Use only factory documented components for repair.
Do not place hands or fingers in the Platform front handles when front panel is open. Dropping the
front panel of the Platform while hand or fingers are inside either handle can cause serious injury.
Ensure that all gas connections are made as labeled and are leak free. Improper gas connections
could result in explosion or death.

HAND INJURY HAZARD
WARNING.
POSSIBLE EXPLOSION HAZARD
WARNING.
POSSIBLE EXPLOSION HAZARD
Protection against explosion depends upon a special fuel flow restrictor in the fuel inlet fitting. DO
NOT REMOVE THE FUEL INLET RESTRICTOR. Use the correct fuel flow restrictor for the fuel being
used. Do not use 100% hydrogen fuel in a 40% H2/60% He configured FID module. Replace with
factory supplied fitting only.
CAUTION .
PRESSURIZED GAS
This module requires periodic use of pressurized gas. See General Precautions for Handling and
Storing High Pressure Gas Cylinders, page P-5.
CAUTION .
OVERBALANCE HAZARD
This analyzer module may tip instrument over if it is pulled out too far and the Platform is not properly supported.

CAUTION.
CONTROLLED ENVIRONMENT
This equipment is for use in a controlled environment. Refer to Section 1-6 Specifications (page 1-
7) in this manual for environmental conditions.
CAUTION.
HOT OVEN COMPONENTS
The oven and sample manifold are controlled to 80°C. Allow the analyzer to cool down before
touching any of these components.
CAUTION.
OVER-VOLTAGE SPIKING
If this analyzer module is used with a non-Rosemount Analytical power supply, adding Rosemount
Analytical PN 903341 Current Protector in series with the 24V positive power line will prevent overvoltage spiking and resultant fuse blowing when powering up the instrument.
Model NGA2000 FID2
CAUTION .
STATIC ELECTRICITY
Circuit boards in this instrument are static-sensitive. Take all static precautions when handling the
circuit boards
NOTE
This Analyzer Module is completely leak-tested at the factory for gas leakage. The user is responsible for testing for leakage at the inlet and outlet fittings on the rear panel (with a test procedure
chosen by the user). The user is also responsible for leak-testing periodically and if any internal
pneumatic components are adjusted or replaced. See leak test instructions in Section 2-6 on page
2-6.

Edited from selected paragraphs of the Compressed Gas Association's "Handbook of Compressed
Gases" published in 1981
Compressed Gas Association
1235 Jefferson Davis Highway
Arlington, Virginia 22202
Used by Permission
1. Never drop cylinders or permit them to strike each other violently.
2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather
and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade when located in areas where extreme temperatures are prevalent.
3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, or
placed in a cylinder stand, and is ready to be used.
4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a suitable hand-truck.
5. Never tamper with safety devices in valves or cylinders.
6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 125
permitted to come in contact with any part of a compressed gas cylinder.
8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding, precautions must be taken to prevent striking an arc against the cylinder.

1-3 THEORY OF TECHNOLOGY
This Analyzer Module uses the flame
ionization method of detection. The sensor is
a burner in which a regulated flow of gas
sample passes through a flame sustained by
regulated flows of a fuel gas (a
hydrogen/diluent mixture) and air.
Within the flame, the hydrocarbon
components of the sample stream undergo a
complex ionization that produces electrons
and positive ions. Polarized electrodes collect
these ions, causing current to flow through an
electronic measuring circuit.
The ionization current is proportional to the
rate at which carbon atoms enter the burner,
and is therefore a measure of the
concentration of hydrocarbons in the sample.
The gas pressures are continuously
monitored and controlled through electronic
pressure transducers.
The measurement of concentration is placed
on the network, where it can be shown on the
Platform Display or on other data acquisition
devices.

1-4 GAS SAFETY FEATURES
The FID2 module is divided into two parts - a
pneumatic section and an electronic section.
The two sections are separated by a pair of
solid partitions to prevent any leak of gas in
the pneumatic section from reaching the
electronics. The electrical connections into
the pneumatic section are made intrinsically
safe by a series of over-voltage protection
devices and current limiting resistors. The
burner itself is an explosion-proof assembly.
The combination of these two techniques
allows the analyzer to meet international
safety standards without the use of an
expensive continuous-dilution purge - but
ONLY when it is installed in a general purpose
area with good air circulation.
WARNING
POSSIBLE EXPLOSION HAZARD
Hydrocarbon concentration(s) in the sample gas must be below the Lower Explosion Limit (LEL).
The FID2 is designed to use 40% H
fuel at a maximum inlet pressure of 3446 hPagauge (50 psig).
1
WARNING
POSSIBLE EXPLOSION HAZARD
Protection against explosion depends
upon a special fuel flow restrictor at the
fuel inlet. DO NOT REMOVE THE FUEL INLET RESTRICTOR.
1-5 FUEL GAS OPTION
The standard FID2 Analyzer Module requires
40% hydrogen/60% helium burner fuel gas.
For monitoring internal combustion exhaust
emissions or other sample gas with varying
oxygen content, mixed fuel is preferable. In
fact, a hydrogen/helium mixture is more
desirable than a hydrogen/nitrogen mixture.
With this type of sample, the use of mixed fuel
gas minimizes the error introduced by oxygen
synergism.
/60% He
2
All tubing ahead of the burner is rigid metallic
tubing assembled with ferrule/nut type
compression fittings. However, should an
internal fuel leak occur, a worst-case leak
would be dissipated below 25% of the LEL of
hydrogen by natural dilution outside of the
pneumatic section before it could be ignited
by any external ignition source, and there is
nothing within the pneumatic section to ignite
it.
Changes in the burner air flow rate have little
effect on signal strength. For a given flow, the
signal can be optimized by adjusting the fuel
flow rate.

INSTALLATION
2-1 UNPACKING
When the FID2 Analyzer Module is received,
carefully examine the shipping carton and
contents for signs of damage. Immediately
notify the shipping carrier if the carton or
contents is damaged. Retain the carton and
packing material until all components
associated with the Analyzer Module are
operational.
2-2 ASSEMBLY
The FID2 analyzer module MUST NOT be
placed within a conventional NGA platform,
single module enclosure or dual module
enclosure since the latter would not allow free
flow of air around the module, thus violating
its safety certification. The enclosure is
designed so that this would be very hard to do
anyway.
There is a special platform specifically
designed to accept this module; consult the
factory for details.
2-3 LOCATION
WARNING.
POSSIBLE EXPLOSION HAZARD
Do not place the FID2 module within another enclosure unless the latter has a
guaranteed air circulation such as to dilute
a worst case fuel or sample leak below
25% of the LEL. Failure to will negate the
safety features and may result in explosion, serious injury, material damage and
death. Also, do not cover the vent holes
on the top and sides of the module.
Install the Analyzer Module in a clean,
weather-proofed, non-hazardous, vibrationfree location free from extreme temperature
variations. For best results, install the
Analyzer Module near the sample stream to
minimize sample transport time.
Operating ambient temperature is 5 °C to
40 °C, limited to temperature changes of less
than 10 °C/hr. Acceptable dew point range is
less than 95% relative humidity, but not in
excess of 40°C wet bulb temperature.
The cylinders of fuel, air, and calibration
gases should be located in an area of
relatively constant ambient temperature.
CAUTION .

Storing High Pressure Gas Cylinders, page
P5.
2-4 GASES
a. Overview
During normal operation, the Analyzer
Module requires fuel and air to maintain
the burner flame as well as suitable
standard gases for. Refer to the criteria
for selection of these gases in Section 24c on page 2-2.
After initial startup or after startup
following a prolonged shutdown, the
analyzer may display baseline drift for a
considerable period of time, particularly
on the most sensitive range.
Commonly, the drift is caused by small
amounts of organics (such as
hydrocarbons) in the inner walls of the
tubing in both the internal flow system and
the external gas supply system. Drift
results from any factor influencing the
equilibrium of these adsorbed
hydrocarbons, such as temperature or
pressure. Hydrocarbons adsorbed within
the analyzer in the gas passageways (or
Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-1
Instruction Manual
760002-A
July 2002
Model NGA2000 FID2
in the fuel or air lines) will elevate the
overall baseline.
Note that this type of drift occurs only
when the flame is burning. If drift occurs
when the flame is extinguished, the
electronic circuitry is at fault or the burner
or cabling is contaminated with a
conductive film. To minimize drift, use
clean fuel and air, keep the analyzer
clean, and locate the gas cylinders in an
area of relatively constant ambient
temperature.
The cylinders supplying all gases each
should be equipped with a clean,
hydrocarbon-free, two-stage regulator and
a shutoff valve.
All new external gas tubing (except for
SAMPLE BYPASS) is strongly
recommended, preferably pre-cleaned,
stainless steel, gas chromatograph-grade
tubing. Thoroughly clean before use (if a
hydrocarbon-based cleaning solvent such
as acetone is used, purge tubing with dry
nitrogen or helium for several minutes
before using.)
Gas line connections are compression
fittings. Do not use pipe thread tape on
such fittings.
Since the oxidation of hydrogen is
accompanied by the formation of water
vapor, the exhaust tubing always should
be slanted downward at least 6 degrees
from horizontal. Otherwise, water may
accumulate in the line, causing back
pressure and noisy readings, or may back
up in the line and flood the burner.
If the sample is toxic or noxious, or is to
be reclaimed, connect the Bypass outlet
to a suitable disposal system. Do not use
any device that may cause back pressure
in the line.
to appropriately labeled fittings on the rear
panel. All connections are 1/4-inch
ferrule-type compression fittings. Burner
exhaust and bypass must be vented at
atmospheric pressure to a non-classified
location in accordance with ANSI/NFPA-
496.
c. Gas Specifications
Fuel Gas — Standard analysis usually
requires mixed fuel, i.e., 40% (±2 %)
hydrogen and 60% helium. H
fuel is recommended over H
because of better linearity in
concentration output. Such blends are
supplied by many gas vendors specifically
for this use, with a guaranteed maximum
total hydrocarbon content of 0.5 ppm,
measured as methane. This specification
should be used when obtaining these
mixtures.
Burner Air — In order to ensure a low
background signal, hydrocarbon free
grade air with less than 1 ppm maximum
total hydrocarbon content is highly
recommended. An alternative source for
burner air and zero gas (see Calibration
Gases below) is a combination diaphragm
pump and heated palladium catalyst. This
process continuously removes moderate
amounts of hydrocarbons and carbon
monoxide from ambient air.
Calibration Gases — Calibration method
and gases depends on the type of fuel
gas used, the operating range, and the
desired measurement accuracy. In all
methods, zero and span gases are used,
and are introduced through the sample
inlet at the rear of the module.
Zero Gas It is recommended that the
gas should have a composition as close
to the background composition of the
sample as possible.

Model NGA2000 FID2
Instruction Manual
760002-A
July 2002
Sample Gas — Sample gas must be
nonflammable (below 100% of the
sample's LEL).
Flow Rate — The sample flow rate must
be between 0.5 L/min. and 2 L/min.
Pressure/Filtration — See Table 2-1 on
page 2-4 for input pressure specifications.
Noncompliance with these specifications
could cause over-pressure damage to the
module.
All internal pressure settings are preset at
the factory, but the operator should check
for accuracy. It is essential that the
4.3
[110]
8.2
[208]
sample be filtered for particulates
down to 0.1 microns. A suitable filter is
the Balston type 95S6 with 0.1 micron
filter element. It should normally be
replaced on a two week schedule,
depending on the sample.
Leak Test — The Analyzer Module is
completely tested at the factory for gas
leakage. The user is responsible for
testing for leakage at the inlet and outlet
fittings on the rear panel. The user is also
responsible for internal leak testing
periodically and if any internal pneumatic
components are adjusted or replaced
(with a test procedure chosen by the
user).

2-6 ANALYTICAL LEAK CHECK
The FID2 Analyzer Module is completely
tested at the factory for gas leakage. The user
is responsible for testing for leakage only at
the inlet and outlet fittings on the rear panel.
CAUTION
SENSOR PRESSURE
Do not expose the Sensor to pressure in
excess of 1.0 psig as this may cause damage.
a. Flow Indicator Method
Supply air or inert gas such as nitrogen,
at 1 psig (6.8 hPa), to the analyzer
through a flow indicator with a range of 0
to 250 cc/min. Install a shut-off valve at
the sample gas outlet. Set the flow rate to
125 cc/min.
b. Manometer Method
Install a water-filled U-tube manometer at
the sample gas outlet. Install a shut-off
valve at the sample gas inlet. Admit air or
inert gas to the inlet shut-off valve until
the analyzer is pressurized to
approximately 50 hPa. The water column
will be about 500 mm.

Figure 2-5. Leak Test - Manometer Method
Close the inlet shut-off valve and,
following a brief period for pressure
equilibrium, verify that the height of the
water column does not drop over a period
of about 5 minutes. If the water column
height drops, the system is leaking and
must be corrected before the introduction
of any flammable sample gas or
application of power.
c. Troubleshooting Leaks
Liberally cover all fittings, seals, and other
possible sources of leakage with a
suitable leak test liquid such as SNOOP
(part 837801). Bubbling or foaming
indicates leakage. Checking for bubbles
will locate most leaks but could miss
some, as some areas are inaccessible to
the application of SNOOP. For positive
assurance that system is leak free,
perform one of the tests in Section 2-6
above.

In case of power failure, all user defined
specific module parameters are saved by a
battery powered memory.
The Function Keys, also called softkeys,
are assigned values depending on the
menu or screen being displayed. The
legend is displayed above the keys.
The Enter Key is used to confirm a
previously entered variable value, to start a
selected function or to go to a submenu
selected at a menu line as opposed to the
Function Keys. As an alternate to using the
Enter Key to start a function, the → key
can be used.
The Cursor Keys (↑ or ↓) are used to
move up or down the lines within a menu
or to increment and decrement number
variables.
The Cursor Keys (← or →) are used to
move backwards or forwards between the
pages of a menu or to select numeric digits
for adjustment.

WARNING
VENTILATION
For safety, the Analyzer Module should
be installed in a non-confined, ventilated space. Do not block any of the
ventilation holes as they are part of the
safety system.
1. Connect supply gases and outlets
to/from module.
2. Connect the LON cable(s) and the
+24VDC power cable.
3. Apply power to the FID2 Analyzer
Module. If it is associated with a
Platform, do this by plugging in the
Platform to a power source. The
Platform has no ON/OFF power
button. Once power has been supplied
to the Platform, the FID2 Analyzer
Module will be energized.
4. Check the LED’s. The power green
LED should be illuminated. The Flame
LED should be OFF. The block LED
should be blinking or ON.
5. After switching on the FID2, the
analyzer will begin its booting
procedure which is apparent on the
LCD screen. The first part of the
initialization procedure is a self check
of the software and analyzer
components. Various displays will
show the status of the initialization
including revision notes, “Initializing
network interface,” “Searching for
nodes,” “Scanning Module 2: PFD
(module number may differ depending
on installed modules), 12% Complete,”
and “Calculating bindings.”

6. If the user's system contains only one
Analyzer Module, all system
components, the Controller Board and
the network "self-install" (bind
together) during initial startup. If the
system contains more than one
Analyzer Module, the startup sequence
will interrogate the network to locate
and identify all components on the
network. The user will have to bind
appropriate combinations of
components after the startup
sequence. See Section 3-3c on page
3-12 for instructions on binding
combinations of modules.
Pressing the F1 key during initializing
will reset the LCD brightness and
contrast to factory settings (See
Section 3-7 on page 3-18). Pressing
the F3 key will abort the network
initializing, aborting any connection to
other analyzers. In that case, only the
menus of the local analyzer will be
available.
7. At the end of the initializing routine the
“measure” screen will display as
shown in Figure 3-1 on page 3-1. This
screen is the access to all other
channels, menus and submenus. The
actual display may differ from that
shown depending on any custom
configuration as described in Sections
3-8h on page 3-28 and 3-8j on page 3-

c. Binding
Model NGA2000 FID2
To achieve full coordination between
Analyzer Modules and associated I/O
Modules, the user must bind those
components together. (See the
Platform manual for binding
instructions.)
NOTE
If binding is attempted after ignition,
the flame may be extinguished. If
this occurs, it must be re-ignited
according to Section 3-3a on page
3-9.
d. Optimization
Although the module has been set up
for best operation at the factory,
settings can change and your
application may be different. The
following shows how to optimize the
operation of the FID2 for your
application.
1. Ignite the flame of the FID2 using
the startup procedure as above.
2. Verify that the mixed fuel supply
pressure at the Analyzer’s rear
panel bulkhead is between 49 and
50 psig.
3. Allow the Analyzer module
response to stabilize. Typically
allow 1 to 4 hours.
6. Set the internal burner air pressure
to between 965 to 1103 hPagauge (14 to 16 psig). The burner
air pressure must be kept constant
throughout the optimization
procedure.
7. Set the internal fuel pressure to
345 hPa-gauge (5 psig). Calibrate
the instrument as stated below.
8. Introduce the span gas and
monitor the reading until it is
stable. Increase the internal fuel
supply setting in the following
sequence: 600 hPa-gauge (8.7
psig), 625 hPa-gauge (9.1 psig),
650 hPa-gauge (9.4 psig), 675
hPa-gauge (9.8 psig), 700 hPagauge (10.1 psig), and 725 hPagauge (10.5 psig). Monitor the
reading at each fuel pressure
setting. Wait at least 2 minutes
between fuel setting changes.
Record all the readings.
9. Review the readings for each fuel
pressure setting. Select the fuel
pressure setting that produces a
reading that is within 1% from the
maximum. For this condition the
FID2 is operating at its optimized
plateau.
e. Shut Down Procedure
4. Select the desired range to
optimize. For best results use a
span gas with a concentration of
100 ppm CH4 or greater. This will
minimize the effects of the THC
contamination in the fuel and
burner air supply.
5. Set the internal sample pressure to
the desired operating level. The
sample pressure must be kept
constant throughout the
optimization procedure.

down state for any length of time
greater than a few hours, it is important
that the flame tower be dried out
before it cools off. This is to avoid
condensation causing corrosion. If the
sample contains halogenated
compounds this is even more
important.
During shutdown, always turn off fuel
gas first, then the air and sample
gases. The flame can also be turned
off by setting Ignition System Enable to
Model NGA2000 FID2
Instruction Manual
760002-A
July 2002
"Off" in the Light Flame menu (under
Basic Controls). Subsequently,
remember to set Ignition System
Enable to "On" before attempting to
ignite the flame.
Flush the flame tower with burner air
for around an hour after the flame has
been turned off. Simply leave the
burner air flowing. When no evidence
of condensation can be seen in the
exhaust tubing, it is safe to switch off
the FID2 power.
If this precaution is not taken,
corrosion can occur making it hard or
impossible to light the flame.
f. Safety System
The FID2 Analyzer Module safety
system is entirely passive. The
pneumatic section of the analyzer is
designed to be intrinsically safe,
except for the flame tower itself which
is designed to be explosion proof.
Intrinsic safety design ensures that any
energy released in the hazardous area
(the pneumatic section) will not be
enough to ignite any hydrogen that
may have leaked. This is achieved by
limiting the voltage and the current in
all the circuitry that enters this area. It
is therefore essential that NO
modifications are done to the circuit
boards. Any repairs should be
performed at the factory where the
correct components will be used.
The flame tower is designed to be
explosion proof. This is achieved by
careful control of the spacing and
clearances of the assembly, and the
presence of the various flow restrictive
devices and the outlet flame arrestor. It
is essential that no changes be made
to this device that can impact any of
these clearances, and thus that any
repairs of the device are such as to
maintain its designed clearances. It is
recommended that any repairs of the
flame tower be performed in the
factory or at other authorized
Rosemount service centers.
A temperature safety system
activates when the burner flame
temperature exceeds 225
60 seconds. This will shut off the fuel
and display a message on the light
flame menu screen. After cooling to
below 225°C, the unit can be re-ignited
normally.
Verify that the proper fuel is being
used. Do not use H
configured for mixed fuel (H
Since the proper methane – nonmethane process should be run under

3-4 ROUTINE OPERATION
The FID2 Analyzer Module is designed to
continuously analyze the sample stream.
Normally, it is never powered off except for
servicing or for a prolonged shutdown.
After binding (see Section 3-3c on page 3-
12) and calibration (see Section 3-9 on
page 3-32), proceed as follows:
Supply sample gas to the SAMPLE INLET.
Adjust external flow controller or throttle
valve so that flow discharged from the
BYPASS outlet is between 0.5 and 1.0
L/min. The reading on the SAMPLE
pressure gauge should be the same as
that used during adjustment of the span
control. Adjust, if necessary.
Adjust the Range Number setting.
If maximum sensitivity is required from the
FID2 Analyzer Module, use an optimum
combination of settings on the SAMPLE,
FUEL, and AIR pressure controllers.
Settings must be determined
experimentally, but the curves in Figure
3-12 on page 3-10, Figure 3-13 on page 310, and Figure 3-14 on page 3-11 may be
used as guides for the FID2 optimization
procedure in Section 3-3d on page 3-12.
The Analyzer Module will not allow the
user to increase the upper limit of a range
beyond the maximum range software
setting. To change the Maximum Range
value, select the following from the Main
Menu:
Main Menu
↓
Analyzer and I/O expert controls & setup…
↓
Analyzer Module Controls…
↓
Range settings…
Select “Range x upper limit”, and use the
arrow keys to scroll the indicated value.
The same applies for the “Range x lower
limit” value.
After initial startup, or startup following a
prolonged shutdown, the FID2 Analyzer
Module requires about one day's
continuous operation to stabilize. For
several days afterwards, calibrate daily.
The frequency of subsequent calibrations
can be reduced as experience dictates,
consistent with the accuracy requirements
of the particular application. Maximum
permissible interval between calibrations
depends on the analytical accuracy
required, and therefore cannot be
specified.

Linearization parameters allows the
establishment of linearizer coefficients
and the assignment of coefficient sets
to individual ranges. The linearization
parameters are only used by qualified
service personnel for troubleshooting.
The linear polynomials act over a
range (not the same as the
measurement range). The system
uses the linearizer polynomial
appropriate for the measurement
range chosen. This is the polynomial
with the next higher range. It is,
however, possible to specify that the
analyzer use a wider range polynomial.
Note that the use of different
polynomials on different ranges will
give different readings on a new range.

First, disable the correction.
Set the point being measured to
Point 1.
The analyzer does not test for
monotonicity when it spans, but this
test may not catch all possible errors.
Monotonic means that the curve does
not change direction as the gas
concentration increases.
Midpoint Correction Set Up
This function allows the adjustment of
the primary variable output into a
precise value using up to three
midpoints. It does this with a
piecewise-linear algorithm that occurs
after and in addition to any polynomial
linearization.
The correction can be performed
individually for each range.
Then enter the first midpoint gas value,
run the gas, and when stable, press
“SET.” “Point 1 reading” will show the
actual reading, but the analyzer will
adjust it to the correct value.
Repeat the above steps with the
second and third points as desired.
When complete, se the “Correction:”
line to “ENABLED” to activate the
correction.
CAUTION.
Make sure that the corrections are not
excessive. If the correction is too excessive, the calibration routine will fail
and calibration of the analyzer will not
be possible.

3-9 CALIBRATION METHODS
Model NGA2000 FID2
a. Overview
The FID2 analyzer module may require
periodic calibration with known zero
and span gases in order to maintain a
desire level of analytical accuracy. It is
recommended, after initial startup, that
the FID2 Analyzer Module is calibrated
at least once every 24 hours. This
practice should continue until evidence
indicates that some other interval is
more appropriate depending on the
analytical accuracy required.
Calibration is the process of flowing
know zero or span calibration gas into
the analyzer for a specified period
(averaging time), after which the
analyzer will automatically set its zero
or span factors so that the
concentration measurement equals the
calibration gas value. A limit can be
set, beyond which any attempt by the
analyzer to reset its concentration
measurement will cause a warning
alarm. In this case, user intervention
would be required to reset the alarm
and attempt another calibration.
There are three methods for
performing a calibration with the FID2
Analyzer Module and NGA Platform:
Basic controls calibration, Expert
controls calibration, and System
calibration.
c. Expert Controls Calibration
See Section 3-12 on page 3-36.
This method allows the user to perform
a zero or span calibration for each of
the four ranges, enable or disable the
calibration adjustment limits, view the
results, and view or change the
Factors that the analyzer uses to
adjust the zero and span concentration
reading. This method uses calibration
parameters established in the module
setup menus. (See Section 3-10 on
page 3-33)
d. System Calibration And Setup
This method allows the user to
establish complex automated
calibration sequences for modules
bound to the Platform. This is fully
described in the Platform manual.
NOTE
If zero calibration is done with other
than a true zero gas followed by a
span calibration, it may be necessary to repeat the calibration. This
is due to the slope/intercept effect
where the subsequent span calibration may change the zero crossing
point.
b. Basic Controls Calibration
See Section 3-11 on page 3-35.
This method allows the user to input a
span calibration gas value and perform
a zero or span calibration for each of
the four ranges. This method uses
calibration parameters established in
the module setup menus. (See Section
3-10 on page 3-33)

b. Response Factor
THE FID2 provides selective response
to hydrocarbons (organic compounds).
The FID2 signal is approximately
proportional to the number of carbon
atoms in the sample gas. Depending
on the molecular structure of the gas,
the FID2 can show a different
response that is compensated by the
Response Factor.
The ions in the flame are created by
the oxidation process. Pre-oxidized
hydrocarbons thereby contribute less
to the ion creation and the resulting
FID signal. The response of preoxidized hydrocarbons is therefore less
than that of non-oxidized hydrocarbons
like propane. The higher the oxidation
level of the carbon atom in the
molecule, the lower the response of
the substance.
Since Response Factors are analyzer
design specific, each type of analyzer
uses different factors. Response
Factors for the FID2 are relative to

b. Calibration Factors
Calibration Factors can be used to
manually set a calibration by flowing
calibration gas and setting the Factor
for zero or span until the reading
conforms to the calibration gas value.
In this way, the user can force the
analyzer to any desired reading.
Alternately, the Factors can be viewed
and recorded after an automatic
calibration.
NOTE
If zero calibration is done with other
than a true zero gas followed by a
span calibration, it may be necessary to repeat the calibration. This
is due to the slope/intercept effect
where the subsequent span calibration may change the zero crossing
point.
In the “Zero/span Calibration” menu
(Figure 3-51 on page 3-37), verify the
“Measurement range number:” is set to
the desired range. If not, move the
cursor to the “Measurement range
number:” line and change the setting.
Press the FACTORS (F2) softkey.
The “Calibration Factors” menu is
displayed.

c. Calibration Details
The range change resistor in the
preamp has some effect on the way
the spans work. In most NGA
analyzers it is possible to make them
zero and span all ranges together or
separately. If this option is selected,
the analyzer attempts to determine if a
zero or span is appropriate using the
supplied zero and span gases, and if
the gases are suitable it will go ahead
and zero or span as many ranges as it
can. The FID2 however may switch
gains between ranges, and if so it will
not be able to zero or span the ranges
on the other side of the switching point.
The switching point is determined by a
number of factors, including the gas
response factor, the sample pressure,
the type of fuel and the capillary used.
In general it will occur at about
600ppm of methane on a low range
instrument. This means that if the
ranges are set at 10, 100, 1000, 5000,
the analyzer will be able to span the
lower two, or the higher two at once,
but not all four.
Generally, it is best to operate the
analyzer on a single range and
calibrate that, or to calibrate the ranges
individually.
If the user is unable to calibrate the
Analyzer Module (i.e., when ZERO or
SPAN is initiated, nothing happens), a
possible solution relates to the use of
an incorrect gas for zeroing or
spanning (e.g., using a high
concentration gas to zero or a zero gas
to span the Analyzer Module). Simply
recalibrating with the appropriate
gas(es) will not correct the problem
because the ZERO OFFSET or SPAN
FACTOR has been set to an extreme
value in the process.
To remedy the problem, do the
following:
1. Verify that correct zero and span
calibration gases are being used
properly. If so, attempt to
recalibrate according to Section 312 on page 3-36, ensuring that
case temperature and displayed
measurement reading are stable
before initiating the calibration
routine. If incorrect gases were
used in the initial, failed calibration,
skip to Step 2.
2. Select the following from the Main
Menu: “Analyzer and I/O Expert
Controls & Setup,” “Analyzer
Module Set Up,” and “Calibration
Parameters...”
3. Using the ↓ arrow, select “Zero
Ranges:”, press ENTER and,
using the up/down arrows, toggle
to SEPARATE. Do the same for
the “Span Ranges:” selection. Do
not press ESCAPE at any time
unless retention of prior settings is
desired.
4. Return to the Main Menu and
make the following selections:
“Analyzer and I/O Expert Controls
& Setup,” “Analyzer Module
Controls,” “Zero/Span Calibration,”
FACTORS (F3) softkey, and
Range 1 (2, 3, 4) Factors (do
Steps 4 and 5 for each range).
5. Select “Zero Offset,” press
ENTER, adjust the value to 32700
with the ↑ and ↓ arrow keys, and
press ENTER. Do not press
ESCAPE at any time unless
retention of prior settings is
desired.
6. Select “Span Factor,” press
ENTER, adjust the value to
0.00015 with the ↑ and ↓ arrow
keys, and press ENTER. Do not
press ESCAPE unless retention of
prior settings is desired.
7. Attempt to recalibrate the Analyzer
Module according to the procedure
outlined in Section 3-12 on page 3-
36. If recalibration fails, return to
the Range Factors menu, readjust
Zero Offset and Span Factor
values, and try calibrating again.
