Make a total of three measurements by alternating aero air and the <br /> calibration gas. Record the readings and calculate the average algebraic difference between the <br /> instrument reading and the calibration gas as a percentage. The calibration precision must be less than <br /> or equal to 90%of the calibration gas value. <br /> Instrument ID. ���1 S ��I /( Cal Gas Concentration: ��© ppm <br /> Trial Zero Air Readin Cal Gas Readin Cal Gas Conc.—Cal Gas Readin <br /> 2 p <br /> 3 .00 <br /> Average Difference: 3 <br /> Calibration Precision =Average Difference/Cal Gas Conc.
