WARNING
Only carry out the Fresh Air Setup/bump test in fresh, uncontaminated air;
otherwise, inaccurate readings can falsely indicate a hazardous atmosphere
as safe. If the quality of the surrounding air is uncertain, do not carry out a
Fresh Air Setup/bump test. Do not use the Fresh Air Setup/bump test as a
substitute for daily calibration checks. The calibration check is required to
verify span accuracy. Failure to follow this warning can result in serious
personal injury or death.
