5.1 Calibration
The Model 450 is calibrated to NIST traceable standards on the 0-1 ppm range prior to
shipment. A calibration certificate for your instrument can be purchased from Teledyne
API if required. Teledyne API also recommends that the Model 450 be re-calibrated
once a year. Teledyne API can provide NIST traceable calibration services at our factory
or on-site. Please contact our Customer Service department for details on these services.
5.2 Adjusting UV lamp and detector
Basic operation of the source lamp and detector can be determined by observing the
value of the O3 REF test function. After the analyzer is warmed-up (15 min. to 30 min.
after power-on), this value will give a good indication of the state of Lamp and Detector
operation as follows:
