Do not cut the grounding circuit or disconnect the wire from the grounding terminal.
Defects in protective functions
Before starting the detector, check the protective functions for defects. When seeming defects are
found in the protective functions, such as protective grounding, do not start the detector.
Tubing
The detector is designed to draw gases around it under the atmospheric pressure. Be sure that
excessive pressure is not applied to the sampling inlet and outlet (GAS IN, GAS OUT) of the
detector. Detected gases must be exhausted from the detected gas exhausting outlet (GAS OUT)
to which an exhaust tube is connected, to a point regarded as a safe place.
Span adjustment (AIR adjustment) in atmosphere
When the span adjustment (AIR adjustment) is performed in the atmosphere, check the
atmosphere for freshness before beginning the adjustment. If interference gases exist, the
adjustment cannot be performed properly, thus leading to dangers when the oxygen concentration
fluctuates.
Response to gas alarm
Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on
your judgment.

may cause severe skin burns if it contacts skin, while it may cause blindness if its contacts eyes. If
electrolyte is adhered on your clothes, that part on your clothes is discolored or its material is
