Calibration Reasons for Calibration Why Calibrate? • Provides a known substance to be used Calibration Reasons for Calibration Why Calibrate? • Provides a known substance to be used as a reference to identify contraband. • Compensates for changes in atmospheric pressure and humidity. • Verifies proper system operation. • Auto-Calibration is the preferred method of calibration. • If Auto-Calibration fails, and there are no other warnings, then it will be necessary to perform a manual calibration and then reset the calibration defaults. • Dual Peak is the preferred method for Manual Calibration. PN: TM 001017 rev: 3
