Make a total of three measurements by altemating zero air <br />and the calibration gas. Record the readings and calculate the average algebraic difference <br />between the instrument reading and the calibration gas as a percentage. The calibration <br />precision must be less than or equal to 2% of the calibration gas value. <br />Instrument Serial No. 3 7 3 <br />Calibration Gas: %CH4 %CO2 30 %02P_ <br />Time <br />CH4 <br />CO2 <br />02 <br />Pnc4_mnnitnrinn Calibrafinn Check <br />Time CH4 <br />CO2 02 <br />Calibration Form GEM <br />1 211 2103 9:08 AM <br />i <br />
