Teledyne 200AU instruction manual Activity Matrix for Calibration Equipment and Supplies, NO2

Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

All monitoring instrument systems are subject to some drift and variation in internal parameters and cannot be expected to maintain accurate calibration over long periods of time. Therefore, it is necessary to dynamically check the calibration relationship on a predetermined schedule. Zero and span checks must be used to document that the data remains within control limits. These checks are also used in data reduction and validation. Table 7-9 summarizes the initial quality assurance activities for calibrating equipment. Table 7-10 is a matrix for the actual dynamic calibration procedure.

Calibrations should be carried out at the field monitoring site. The Analyzer should be in operation for at least several hours (preferably overnight) before calibration so that it is fully warmed up and its operation has stabilized. During the calibration, the M200AU should be in the CAL mode, and therefore sample the test atmosphere through all components used during normal ambient sampling and through as much of the ambient air inlet system as is practicable. If the instrument will be used on more than one range, it should be calibrated separately on each applicable range (See Section 7.7). Calibration documentation should be maintained with each analyzer and also in a central backup file.
