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 />I <br />-k , <br />Instrument Serial No. -amts -11 <br />Calibration Gas: %CH4'�;D-a %CO2 ' ' %02 C <br />Time <br />\ CO2 <br />CH <br />CO21�2 <br />�} <br />02 `, <br />b.� <br />.� <br />b .rZ, <br />11 <br />Pnct_mnnitnrinn (-,n1ihrntinn (hPrk <br />Time ' C 4 <br />\ CO2 <br />02 a Z <br />�b .o S`D .p <br />? `� <br />b t� . c) <br />1 <br />
