NOTE
•
Use only a gas sampling hose specified by RIKEN KEIKI.
•
Use the gas detector with the gas sampling probe connected so that no foreign substance is drawn
into it.
•
In a low-temperature environment, the operating time is shortened due to the battery performance
property.
•
At a low temperature, the response of the LCD display may get slow down.
•
If a combustible gas with high concentration such as 100 vol% is drawn, some gas may remain in
the gas sampling hose due to adsorption in the hose, gas sampling probe, etc. After drawing a high-
concentration combustible gas, clean the gas detector to remove the adsorbed gas (draw fresh air
and check that the reading becomes zero).
Performing fresh air adjustment before cleaning it completely will result in inaccurate adjustment,
giving adverse influence on measurement. In such a case, remove the gas sampling hose before
performing fresh air adjustment to avoid inaccurate adjustment.
