10.4.3.SYSTEM AUDIT/VALIDATION

A system audit is an on-site inspection and review of the quality assurance activities used for the total measurement system (sample collection, sample analysis, data processing, etc.); it is an appraisal of system quality.

Conduct a system audit at the startup of a new monitoring system and periodically (as appropriate) as significant changes in system operations occur.

10.5.DYNAMIC MULTIPOINT CALIBRATION PROCEDURE

10.5.1.LINEARITY TEST

In order to record the instrument’s performance at a predetermined sensitivity and to derive a calibration relationship, a minimum of three reference points and one zero point uniformly spaced covering 0 to 90 percent of the operating range are recommended to define this relationship.

The analyzer's recorded response is compared with the known concentration to derive the calibration relationship.

To perform a precision check during the instrument set up, the sources of zero air and sample gas should conform to those described in Section 9.1.2.

Follow the procedures described in Section 9.3 for calibrating the zero points. For each mid point:
