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 5000 Instrument Serial No. 500516 <br /> Calibration Gas: <br /> tCH4 % CO2 % 02 % CO ppm H2S ppm <br /> 15.0 15.0 0.0 <br /> Pre-monitoring Calibration Check <br /> Time CH4 % CO2 % 02 % CO ppm H2S ppm <br /> ' 10:15:00 AM 15.0 15.0 0.0 <br /> ' Post-monitoring Calibration Check <br /> Time CH4 % CO2 % 02 % CO ppm 1-12S ppm <br /> ' 01:20:00 PM 15.0 15.0 0.0 <br /> COMMENT 1: <br /> COMMENT 2: <br /> REVIEWED BY: <br /> Art Jones DATE: 10/25/2013 <br /> r <br />
