Examples of Span gas in a sentence

  • Span gas should be available to enable calibration of gas detection equipment.

  • The analytical accuracy of the calibration gas values shall be within 2.0 percent of NIST gas stand- ards.(17) Span gas values shall be trace- able to NIST SRM’s.

  • Span gas blends: The span gases supplied to any Certified I/M Program Station shall meet BAR 97 specifications.

  • Span gas concentrations shall be no less than 50 percent and no more than 200 percent of the emission concentration corresponding to the permitted emission limit.

  • Enable one or more sensors to exit and access normal operation.Span Gas ValueThe Span gas option increases or decreases the gas concentration for calibration (must match the gas concentration listed on the gas cylinder).After selecting the sensor, press H to scroll to Span gas and press C within 20 seconds to confirm.Depending upon the sensor selected, ascreen similar to A or B displays.

Span gas means a purified gas mixture used to span gas analyzers. Span gases shall meet the specifications of paragraph 9.5.1. Note that calibration gases and span gases are qualitatively the same, but differ in terms of their primary function. Various performance verification checks for gas analyzers and sample handling components might refer to either calibration gases or span gases;
