Calibrate the instrument about every 30 days to assure its accuracy. The
frequency of calibration, however, may change depending on how often
the instrument is used and the amount of gas that was sampled. Create
a maintenance log to keep track of when an instrument was calibrated,
and then use this log to help develop a calibration schedule. For

and then use this log to help develop a calibration schedule. For
example, an instrument that fails its calibration after only being
calibrated a single time should be calibrated more often.
Important:

Important:
Avoid sampling leaded gasoline vapors, or gases or vapors that
contain silicones or sulfur compounds. Tetraethyl lead, silicones, and
sulfur compounds can form contaminating compounds on the sensor
element (poison the sensor), with resulting loss in sensitivity.
