Make a total of three measurements by alternating 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. 0 �-_ 3 <br />isCalibration Gas: %C]44_5%CO2 M,c-) %02 _ <br />0 <br />Time <br />CH 4 <br />CO2 <br />02 <br />5-7.0 <br />M.0 <br />U4 , d <br />Pnct_mnnitnrinn C'.alihratinn Check <br />Calibration Form GEM <br />3/31/06 11:54 AM <br />FFAI <br />Calibration Form GEM <br />3/31/06 11:54 AM <br />
