CAUTION ON SAFETY
First of all, read this “Caution on safety” carefully, and then use the gas analyzer in the correct way.
The cautionary descriptions listed here contain important information about safety, so they should always be
observed. Those safety precautions are ranked in 2 levels, “DANGER” and “CAUTION.”
DANGER
CAUTION
Wrong handling may cause a dangerous situation, in which there is a risk of
death or heavy injury.
Wrong handling may invite a dangerous situation, in which there is a
possibility of medium-level trouble or slight injury or only physical damage
is predictable.
Caution on installation and transport of gas analyzer
DANGER
• This unit is not explosion-proof type. Do not use it in a place with
explosive gases to prevent explosion, fire or other serious accidents.
CAUTION
• Install the gas analyzer in a place that satisfies the conditions described in
the “Instruction Manual.” Otherwise electric shock, fire, or malfunction
may result.
• During maintenance and check, care should be taken to keep the unit free
from cable chips or other foreign objects. Otherwise, it may cause fire,
trouble or malfunction of the unit.
• For lifting the gas analyzer, be sure to wear protective gloves. Bare
hands may invite an injury.
• The gas analyzer is heavy. Two or more persons should carry the gas
analyzer with sufficient care to avoid injury or damage to body.
iv
INZ-TN514401-E
Caution on piping
DANGER
In piping, the following precautions should be observed. Wrong piping
may cause gas leakage.
If the leaking gas contains a toxic component, there is a risk of serious
accident being induced.
Also, if combustible gas is contained, there is a danger of explosion, fire
or the like occurring.
• Connect pipes correctly referring to the instruction manual.
• Exhaust should be led outdoors so that it will not remain indoors.
• Exhaust from the gas analyzer should be relieved in the atmospheric air
in order that an unnecessary pressure will not be applied to the gas
analyzer. Otherwise, any pipe in the gas analyzer may be disconnected
to cause gas leakage.
• For piping, use a pipe and a pressure reducing valve to which oil and
grease are not adhering. If such a material is adhering, a fire or the like
accident may be caused.
Caution on wiring
CAUTION
• Be sure to perform specified grounding work to avoid electric shock or
malfunction.
• Be sure to use a power supply of correct rating. Connection of power
supply of incorrect rating may cause fire.
• Wiring work must be performed with the main power set to OFF to
prevent electric shocks.
• Wires should be the proper one meeting the ratings of this instrument. If
using a wire which cannot endure the ratings, a fire may occur.
Caution on use
DANGER
• For correct handling of calibration gas or other reference gases, carefully
read their instruction manuals beforehand.
CAUTION
• Do not operate the gas analyzer continuously with the cover opened.
Otherwise dust may enter, causing a failure.
• Do not open the cover and touch inside while the gas analyzer is
operated. Otherwise burns or electric shock may result.
INZ-TN514401-E
v
Caution on maintenance and check
DANGER
• Before performing work with the cover opened, be sure to turn off the
power and purge fully not only the gas analyzer but also measurement
gas lines with air and N2 gas. Be careful not to stain the filter and
packing with oil or grease. Otherwise gas leak may occur, thus causing
poisoning, fire, or explosion.
CAUTION
• Be sure to remove metallic objects such as a wristwatch or a ring.
Never perform work with wet hands to avoid electric shock.
• If the fuse is blown, eliminate the cause, and then replace it with the one
of the same capacity and type as before. Otherwise, shock hazard or
fault may be caused.
Others
CAUTION
• If the cause of any fault cannot be determined despite reference to the
instruction manual, be sure to contact your dealer or Fuji Electric’s
technician in charge of adjustment. If the instrument is disassembled
carelessly, you may have a shock hazard or injury.
• Do not use replacement parts not specified by the manufacturer.
Otherwise sufficient performance of the gas analyzer may not be
obtained, or accidents or failure may result.
• Dispose the parts removed for maintenance as noncombustible waste.

6. ADJUSTMENT IN HEAT TREATMENT FURNACE
● What is the adjustment in heat treatment furnaces?
If, in plant gases to be measured actually, a large amount of other lower-molecular-weigh gases than
nitrogen (N2) such as hydrogen (H2), or a large amount of other higher-molecular-weight gases than
nitrogen (N2) such as argon (Ar) are contained, including the measuring components, it is known that the
calibration curve (output performance to gas concentration) of the gas analyzers will be affected (pressure
broadening).
In such a case, the gas analyzer is adjusted with gases similar to plant gas compositions in manufacturing
(adjustment by scale gas). After this adjustment, the gas analyzer is checked the calibration curve with
N2 balance gas (calibration curve by check gas). Graphs with these calibration curves drawn are
attached to products to be supplied.
Since measurement in a heat treatment furnace has much gas of such composition, adjustment in heat
treatment furnaces is performed.
In order to perform exact measurement, there are two methods in span calibration:
Composition of the standard gas for span calibration used for each method and its method are explained
using an example. For the standard gas for zero calibration, use N2 or Air in any case so that zero point
will not be affected.
<Example>
Assume that a 0 to 1% CO2 meter of the infrared gas analyzer measures CO2 contained in plant gases.
When plant gases are composed of 0.5% CO2, 25% CO, 30% H2, 0.2% CH4 and 44.3% N2, either of the
following is used as the span calibration standard gas.
Standard gas type
1 Standard gas with the same
composition as plant gases (scale
gas)
2 Check gas
Composition of standard gas
0.9% to 1% CO2
25% CO, 30% H2, remainder is N2
*
0.9% to 1% CO
Remainder is N2.
Method for span adjustment
Perform span calibration directly.
Perform span calibration indirectly.
* A gas in small amount that has little effect on span calibration such as 0.2%CH4 is not included.
(1) Method for span calibration by standard gas with the same composition as plant
gas
When using the standard gas with the same composition as plant gases given in 1, calibration can be
performed without correction, as an error in calibration curve does not occur.
1) Set CO2 concentration to span calibration concentration set value.
2) Perform span calibration by using the operation key.
50
INZ-TN514401-E
(2) Method for span calibration by check gas
Span calibration is performed as follows when two kinds of check gas are used. (Since span
calibration has an error of calibration curve, preset a calibration indication on the calibration curve
graph attached to this gas analyzer for indirect calibration.)
1) The following calibration curve graph is attached to the test results for the product. In graph, the
calibration curve by the scale gas (that is similar to plant gas and determines scales of this gas
analyzer) and the calibration curve by the check gas that is adjusted by the scale gas (gas of simple
composition of N2 balance gas to facilitate the gas analyzer check) are drawn.

2) When using 0.95% CO2 and remainder N2 (check gas) as calibration gas, in graph, a point of 0.95%
on X-axis should be stretched to upward, draw a line toward Y-axis from the cross point with the
check gas calibration curve. From the cross point with calibration curve on the scale gas
composition, 0.89% or equivalent values can be obtained.
3) Set this point (0.89%) to the span calibration concentration of the calibration concentration set
value.
4) Supply 0.95% check gas to perform span calibration. Then, the concentration value is corrected
to 0.89%. Measurement suited to actual plants can be performed by this error correction of
calibration curve.

1. Airtightness should be maintained. Airtight specifications vary depending
on the product standard.
2. A block cell is or is not provided for the 1st optical cell depending on
the specifications of the range.
(If the block cell is not provided, "Toaron L = 150" piping is not required.)
3. A pipe cell is or is not provided for the 1st optical cell depending on
the specifications of the range.
(If the pipe cell is not provided, "Toaron L = 150" piping is not required.)
4. Pipe dimensional tolerance: +
- 10
5. Use a Teflon pipe as a connecting pipe at the inlet/outlet of the flowmeter.
6. Adjust the length of the fixed diaphragm so that the flow rate is kept at
0.7 L/min (top of the yellow zone) when the pump is ON.
Adjust the length between the diaphragm and the filter using a Toaron tube.
7. Feed the gas at 0.07 MPa from the CAL gas port, and adjust the length of
the fixed diaphragm so that the exhaust velocity is kept at 0.5 L/min.
8. Galvanic type O2 sensor is optionally available. Select it on the PILC code table.
Note that the pipe length is not the same.
