Make a total of three measurements by alternating zero air and the <br /> calibration gas. Record the readings and calculate the average algebraic difference between the instrument <br /> reading and the calibration gas as a percentage. The calibration precision must be less than or equal to 2%of <br /> the calibration gas value. <br /> Instrument Type: GEM 2000 Instrument Serial No. 8049 <br /> Calibration Gas: <br /> CH4 % CO2 % 029/6 <br /> is 15.0 15.0 4.0 <br /> Pre-monitoring Calibration Check <br /> Time CH4% CO2 % 02% <br /> 04:30:00 PM 15.0 15.0 4.0 <br /> Post-monitoring Calibration Check <br /> Time CH4 % CO2 % 02 % <br /> 05:00:00 PM 15.0 15.0 4.0 <br /> COMMENT 1: <br /> COMMENT 2: <br /> REVIEWED BY: DATE: <br />
