Safety Regulations sphere contains the following materials, which may desensitize the combustible gas sensor and reduce its readings: • Organic silicones Lead-containing compounds Hydrogen sulphide exposures over 200 ppm or exposures over 50 ppm for one minute. Check minimum concentration of a combustible gas The minimum concentration of a combustible gas in air that can ignite is defined as the Lower Explosive Limit (LEL). A combustible gas reading of "XXX” indicates the atmosphere is above 100 % LEL or 5.00 % vol CH4, and an explosion hazard exists. Move away from hazardous area immediately....

Safety Regulations Be Aware of Environmental Conditions A number of environmental factors may affect the sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes also affect the amount of oxygen actually present in the atmosphere. Be Aware of the Procedures for Handling Electrostatically Sensitive Electronics The device contains electrostatically sensitive components. Do not open or repair the device without using appropriate electrostatic discharge (ESD) protection. The warranty does not cover damage caused by electrostatic discharges. Be Aware...
