Operating Precautions
The detector detects oxygen in the atmosphere and prevents acid-deficient accidents due to acid-deficient
air release or accidents due to excessive oxygen.
Please fully understand the following points before using it, so that it can be used properly.
1. The detector may be interfered by gases and vapors other than oxygen in the atmosphere.
In addition, it may be fluctuated by environmental (temperature, humidity etc.) changes in the
installation site.
2. The detector is affected by pressure. If the detector is used at a pressure other than atmospheric
pressure, a calibration is required under that pressure. The maximum allowable pressure is 110 KPa.
The detector cannot be used under reduced pressure.
3. The gas sensor used by the detector contains an electrolyte. Electrolyte may cause severe skin burns if
it contacts skin, while it may cause blindness if its contacts eyes. Do not touch the sensor directly in the
event of a liquid leak.
4. For maintenance of the detector, it must go through a regular maintenance, including replacement and
adjustment of the regular replacement parts as specified in the operating manual. In addition, because
this is a safety unit, it is recommended that a regular maintenance and span adjustment are performed
every six months.
