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. CM 6l,R 0 <br /> Calibration Gas: %CH4S5a' %CO2 `315:D %02D' `' <br /> Time CH4 CO2 02 <br /> gyp.� �,,� `� U• � <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 02 <br /> (t-I 00 t .. 3 c , ., b. <br /> NOTES: <br /> Calibration Form GEM <br /> 3/31/06 11:54 AM <br />
