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 readkn 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 19c7 <br /> Calibration Ga %CH4 6a 41 %CO2 �4V 0/602 <br /> Time CH4 CO2 02 <br /> Post-monitoring Calibration Check <br /> Ttme CH4 CO2 . <br /> �® 02 <br /> 6� 2— <br /> NOTES: <br /> Calibration Form GEM <br /> 12/12/03 8:12 AM <br />
