LANDFILL GAS MONITORING <br /> GEM 2000 CALIBRATION AND PERTINENT DATA <br /> Dat Site Name: <br /> Technician: _ Job No. <br /> WEATHER OBSERVATIONS <br /> Wind Speed: MPH Wind Direction: � Barometric Pressure.-7dLL"Hg <br /> Air Temperature- OF Generat Weather Conditions: _ -1 --- <br /> CALIBRATION INFORMATION <br /> Pre-monitoring Calibration Precision Check <br /> Procedure: Calibrate the instrument. 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. <br /> Calibration Gas_ %C1I4SD,0 %CO2 __g5,b %02D -_C> <br /> Time CH4 CO2 02 <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 02 <br /> NOTES: <br /> Callbratlon Form GEM <br /> 313i IDS 11:54 AM <br />
