Periodic Inspections and Calibration
This unit requires calibration. The calibration frequency will be a
function of the operating conditions, including operating under extreme
temperatures, exposure to contaminants or gas concentrations greater
than the lower explosive limits. A calibration inspection must be
included as part of a routine maintenance to ensure proper operation of
the gas detection unit.
If unit span or zero cannot be adjusted, the sensor may be approaching
its end-of-life or has been contaminated and must be replaced.
