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. Q�/\ 15`C>P <br /> Calibration Gas: %CH4�"-_-') %CO2 `:5•y %02 OLO <br /> Time CH4 CO2 O2 <br /> �`�..� <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 02 <br /> zu�, <br /> NOTES: <br /> Calibration Form GEM <br /> 3/31/06 11:54 AM <br />
