Periodic Inspections and Calibration

Periodic Inspections and Calibration
This unit requires calibration. The calibration frequency is dependent
upon operating conditions, including operating under extreme
temperatures, exposure to contaminants or gas concentrations. A
calibration inspection must be included as part of 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 and must be replaced.
