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.c l v► 1���� <br /> Calibration Gas: %CH4—D %CO2 -J %02 D <br /> Time CH4 CO2 O2 <br /> SLA -'b d� <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 O2 <br /> NOTES: <br /> Calibration Form GEM <br /> 12/12/03 9:08 AM <br />
