ALIBRATION
This function calibrates the O
3
Generator that comes with the IZS option, by setting the
IZS O
3
Generator output to a series of levels between zero and full scale, and matching
each level to a drive voltage from the generator lamp. This calibration is typically
performed when the O3 Generator lamp requires adjustment or replacement (Section
5.7.13).
4.6 EPA PROTOCOL CALIBRATION
When running this instrument for U.S. EPA compliance, always calibrate prior to use,
adhering to the EPA designation requirements for this instrument. (The official List of
Designated Reference and Equivalent Methods is published in the U.S. Federal Register:
http://www3.epa.gov/ttn/amtic/criteria.html
)
. Pay strict attention to the built-in warning
features, periodic inspection, regular zero/span checks, regular test parameter evaluation
for predictive diagnostics and data analysis, and routine maintenance. Any instrument(s)
supplying the zero air and span calibration gasses used must themselves be calibrated and
that calibration must be traceable to an EPA/NIST primary standard.
Comply with Code of Federal Regulations, Title 40 (downloadable from the U.S.
Government Publishing Office at http://www.gpo.gov/fdsys/ ) and with Quality Assurance
Guidance documents (available on the EPA website,
http://www3.epa.gov/ttn/amtic/qalist.html ). Give special attention to specific regulations
regarding the use and operation of photometric ozone analyzers.
