lights are illuminated in High sensitivity mode, switch to Low
sensitivity mode by pressing the LOW button
cause most of the indicator lights to turn off. In Low sensitivity
mode, concentration levels are measured in larger intervals than
in High sensitivity mode, meaning greater concentration levels are
required to illuminate each indicator light.
4. As you get closer to the source of a leak, the concentration levels
detected will increase, as indicated by increasing audible/visual
alarms. Move the sensor head in the direction of increasing
audible/visual alerts to the source of the leak.
WARNING: High concentrations of combustible gasses can
cause explosions, fires, asphyxia, and other hazards that
could cause serious personal injury or death. Know the
characteristics of the gas you are working with and use proper
precautions to avoid hazardous conditions.
