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. C" <br /> Calibration Gas: %CH4S5-_' %CO2 <br /> Time CH4 CO2 02 <br /> •c-- <br /> Post-monitoring Calibration Check <br /> Time CH4 CO2 02 <br /> WHO I �Q .
