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. 9/,�;/ <br /> Calibration Gas: %CH4 (!Z7,D %CO2 %02 <br /> Time CH4 Cpl O2 <br /> divr .3 <br /> Post-monitoring Calibration Check <br /> Time CH4 Cpl O2 <br /> /zOU �DrSv <br /> NOTES: <br /> Calibration Form GEM <br /> 3/31/06 11:54 AM <br />
