Maintenance, Safety, and Product Modification
• In order to protect the system controlled by the instrument, and the instrument itself,
and to ensure safe operation, observe the safety precautions described in this manual.
•If any protective or safety circuitry is required for the system used with this instru-
ment, or for the instrument itself, prepare and install it. Do not change the internal
parts or circuitry of the instrument in any way.
Disclaimers (Limitation of Liability)
Yokogawa grants no warranties other than the express warranty set forth under the
warranty provisions.
Yokogawa shall not be liable to you or any third party for any damage, including
consequential or incidental damages, arising out of or in connection with the use of this
equipment, defects beyond our knowledge, or any other contingency beyond our control.

Power
Be sure to check the power supply voltage before turning on the power.
Grounding
Be sure to connect a Class D (100Vor less) ground before turning on the power, to
minimize the possibility of shock.
Need for Grounding
Do not cut the internal or external protective ground wire, or remove the ground wire
from the terminal. This creates a shock hazard.
Do not Operate without Protective Grounding and Fuse
Do not operate the instrument without protective grounding and correct fuse.
Fuse
For safety, this product is fused internally. It is recommended that you ask the local
service representative to change the fuse; do not either change it yourself, or open the
case to check the fuse. Turn off the power switch and disconnect the instrument from
the power before changing the fuse. Do not use a fuse of different type or size, or short-
circuit the fuse holder.

Safety Precautions
Environmental Restrictions
Danger: Do not use this instrument in a flammable, explosive, or steamy environment.
Do not try to measure gases with traces of redox gas, corrosive gas, or organic silicon(e)
gas.
Keep Hands Out
While voltage is applied, keep hands out. Internal parts should be replaced by our
service representative, or by an authorized person.
External Connections
Before wiring, to minimize the possibility of shock, disconnect power from the instru-
ment. Also check ground connection to this instrument, to the system being measured,
and to any associated external control equipment

• the use of software, hardware, or spare parts not supplied by Yokogawa.
• improper or insufficient maintenance by the user.
• unauthorized modification, abuse, misuse or mishandling.
• improper installation or transportation of the equipment.
• the use of unspecified power supply (voltage, frequency) or abnormal power supply.
• use under conditions not meeting the required standards, or improper maintenance of
the installation site.
• force majeure events – including, but not limited to, fires, earthquakes, windstorms,
lightning, riots, civil disorder, war or other hostilities, radiation contamination, or acts
of God.
Yokogawa makes no warranty with respect to the fitness of this equipment for a
particular user purpose. In no event shall Yokogawa be liable for direct, incidental or

Safety Precautions
Notes on Use
• Do not drop or jolt the equipment, or its accuracy may be adversely affected.
• Do not attempt to disassemble the equipment, or it may malfunction.
• As far as possible, install the equipment horizontally. The sensor should be installed
securely so that it does not vibrate. Avoid installing the equipment in places where
the temperature exceeds 70°C.
• Avoid installing the equipment where it would be exposed to direct sunlight, radiant
heat, or the weather, and where vibration exists.
• Avoid installing the equipment in atmospheres containing corrosive gases, gas
atmospheres out of measuring scope, or atmospheres where the sensor is exposed to
silane silicone gas.
• Keep the equipment away from noise-generating devices to minimize the possibility of
malfunction, although it is designed to cope with noise.
• The sensor has a limited life, which varies depending on operating conditions. It is
strongly recommended that you replace the sensor once a year from a preventive
maintenance standpoint.
• Keep this instruction manual handy for your quick reference during operation and
maintenance.

Restrictions on Use
• Do not use the equipment in atmospheres containing combustible, corrosive, or flue
gases, or organic compounds.
• If it is used in silicon gas atmospheres, in flow furnaces or nitrogen reflow furnaces,
the equipment must be used in the following system:
• The sampling unit, K9424GA, must be used.
• The sampling unit requires appropriate maintenance, which is determined by gas
conditions. Filters and activated carbon packs should be replaced at intervals which
depend on the operating conditions.
For best measurement, use new activated carbon packs. Using expired packs may
result in invalid measurement results, or even sensor deterioration.
• If you have any questions, please contact your Yokogawa representative.
