Alarm setting can be changed in five levels among grid 1 to 5.
Note
• Unit conversion is estimated value when it assumed as pump flow rate is approx. 20ml/min and
steady and measured by “Grid 1”.
The actual conversion value is affected by the age of the pump and varies from pump to pump.
• High-concentration or continuous contact with a chloride or sulfur compound will shorten the sensor
life or cause larger errors.
• If a Si compound is detected, the sensitivity will decrease.
• If a high-concentration solvent gas is drawn, the rubber seal used in the detector will deteriorate.
