5.1 Equipment Calibration<br />
Chapter 5<br />
Quality Assurance/Quality Control<br />
All project instrumentation is calibrated annually or verified as part of standard operating<br />
procedures. Certificates of calibration are kept on file. Maintenance records are kept for any<br />
equipment adjustments or repairs in bound project notebooks that include the data and<br />
description of maintenance performed. Instrument calibration procedures and frequency are<br />
listed in Table 5-1 and further described in the text.<br />
