Record the readings and calculate the average algebraic dfference <br /> between the instrument reading and the caribrabon gas as a percentage. The callbration <br /> precision must be less than or equal to 2%of the calibration gas value. <br /> Instrument Serial No.C <br /> Calibration Gas: %CH4.5D -O%CO2 0 %02 D-D <br /> Time CH4 CO2 02 <br /> 34 4 nx <br /> Post- onitoring Calibration Check <br /> I Time I CH4 CO2 02 <br /> NOTES: <br /> Calibration Form GEM <br /> 1 211 2103 9:08 AM <br />
