7. CAUTION OF USAGE
The following caution items must be followed to maintain the performance and safety of the
instrument.
Danger
> Specification of this instrument is based on a non-explosive structure. Do not use it in a place
specified as a hazardous area.
> Make any solutions for exhaust gas emitted from GAS OUT to avoid harmful gas from emission (e.g.
connecting a sampling bag to GAS OUT.)
> In case of instrument leakage, a mask should be worn at all times.
Warning
> The instrument shows incorrect indication when it samples a high concentration gas over the full
scale.
> Use the batteries based on the specifications.
> Use the specified AC adaptor if necessary.
Caution
> Do not use this instrument close to other apparatus that generates a strong noise. It may affect the
wave form of the power source. If the AC adaptor is applied, do not use the same power source as
the other apparatus.
> Use the power source based on the specifications.
> Do not operate the instrument in a place which has a reaction heat such as infrared emitted from
high temperatures. Also, be sure to avoid a place which has a direct sunbeam that makes the
instrument over 35ºC.
> Interference Gas: The gases which are neither the target gas nor base gas.
If there is any interference gas in the measuring gas, the reading will be incorrect. Do not measure
gas containing interference gas.
> Expose GAS OUT and REF. OUT to the air in order to match the pressure inside to the atmospheric
pressure.
> When operating this instrument, keep it in a carrying case and connect the absorption tube.
