About use
To measure a harmful or explosive gas, take a measure to prevent diffusion of the discharged
gas such as attaching a gas sampling bag to the gas outlet (GAS OUT).

2-2. Warning cases
WARNING
Sampling point pressure
The concentration meter is designed to draw gases around it under the atmospheric pressure.
If excessive pressure is applied to the gas inlet (GAS IN) and outlet (GAS OUT) of the
concentration meter, measuring gases may leak out from its inside and may cause dangerous
conditions. Be sure that excessive pressure is not applied to the concentration meter while
used.
Do not connect the gas sampling hose directly to a location with a pressure higher than the
atmospheric pressure. The internal piping system may be damaged.
Reference gas calibration in the atmosphere
When the reference gas calibration is performed in the atmosphere, check the atmosphere for
freshness before beginning the calibration. If interference gases (other than measuring and
base gases) exist, the adjustment cannot be performed properly, thus leading to dangers when
the gas leaks.
Battery level check
Before use, check that there remains sufficient battery power. When the concentration meter is
used for the first time or is not used for a long period, the batteries may be exhausted. Either
fully charge the batteries or replace them with new ones before use.
If a battery error occurs, measurement cannot be performed. If the error message is displayed
during use, turn off the power and promptly replace or charge the batteries in a non-hazardous
area.
Others
Do not draw a high-concentration gas beyond the measuring range. Accurate readings cannot
be obtained.
Do not throw the concentration meter into fire.
Do not block the buzzer sound opening. No buzzer sound can be heard.
Do not remove the battery unit while the power is on.
Use dry batteries of the specified ratings for the concentration meter.

2-3. Precautions
CAUTION
Do not measure gases that contain interference gases.
If a measuring gas contains an interference gas (other than measuring and base gases),
accurate readings cannot be obtained.
Do not measure gases that contain interference gases.
The gas inlet and outlet should be at the atmospheric pressure.
Keep the gas inlet and outlet at the atmospheric pressure.
Do not use the concentration meter where it is exposed to oil, chemicals, etc. Do not submerge the
concentration meter under water on purpose.
Do not use in a place where the concentration meter is exposed to liquids such as oil and
chemicals.
The concentration meter, being compliant to IP67, is not water-pressure-resistant. Do not use
the concentration meter where a high water pressure is applied to it (under a faucet, shower,
etc.) or submerge it under water for a long time. The concentration meter is water-proof only in
fresh water and running water, and not in hot water, salt water, detergent, chemicals, human
sweat, etc.
The gas inlet and outlet are not water-proof. Be careful not to let water such as rainwater get
into these parts. Because this may cause trouble and gas cannot be measured.
Do not place the concentration meter where water or dirt gets accumulated. The concentration
meter placed at such a location may malfunction due to water or dirt that gets into the buzzer
opening, gas inlet, etc.
Note that drawing in dirty water, dust, metallic powder, etc. will significantly deteriorate the
sensor sensitivities. Be careful when the concentration meter is used in an environment where
these elements exist.
Do not use the concentration meter in a place where the temperature drops below -20ºC or rises
over 50ºC.
The operating temperature of the concentration meter is -20 to 50ºC. Do not use the
concentration meter at higher temperatures, humidities and pressures or at lower temperatures
than the operating range.
Avoid long-term use of the concentration meter in a place exposed to radiant heat (infrared
rays emitted from a high-temperature object) or direct sunlight.
Do not store the concentration meter in a sun-heated car.
Observe the operating restrictions to prevent condensation inside the concentration meter or gas
sampling hose.
Condensation formed inside the concentration meter or gas sampling hose causes clogging or gas
adsorption, which may disturb accurate gas measurement. Thus, condensation must be avoided. In
addition to the operating environment, carefully monitor the temperature/humidity of the sampling
point to prevent condensation inside the concentration meter or gas sampling hose. Please observe
the operating restrictions.

2 Important Notices on Safety 2-3. Precautions
- 7 -
Do not use a transceiver near the concentration meter.
Radio wave from a transceiver near the concentration meter may disturb readings. If a
transceiver or other radio wave transmitting device is used, it must be used in a place where it
disturbs nothing.
Do not use the concentration meter near a device that emits strong electromagnetic waves
(high-frequency or high-voltage devices).
Never fail to perform a regular maintenance.
Never fail to perform a regular maintenance to ensure safety. Continuing to use the concentration
meter without performing maintenance will result in inaccurate gas measurement.
Others
Operate the concentration meter using only the procedures described in this operating manual.
Do not drop or give shock to the concentration meter. The water-proof performance and
accuracy may be deteriorated.
Do not use the concentration meter while charging it.
