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. X237 <br />Calibration Gas: %('H4Sb.D %,CO2 �e,o _ %02 r(i� <br />CO2 i 02 <br />Post -monitoring Calibration Check <br />Time CH4 CO2 <br />NOTES: <br />1 Calibration Form GEM <br />3,131/06 11:54 AM <br />02 <br />
