2-2. Warning cases
WARNING
Power supply
Before turning on the detector, always check that the voltage is properly applied. Do not use an
unstable power supply because it may cause malfunctions.
Need of grounding circuit
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.
External connection
Before connecting the detector to the external control circuit, securely connect it to a protective
grounding circuit.
Span adjustment in atmosphere
When the span 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.
Handling of sensor
Do not disassemble the sensor used by the detector because it contains electrolyte. Electrolyte 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
decomposed. If contact occurs, rinse the area immediately with a large quantity of water.
