To manually calibrate the instrument see O3 Background and O3 Coefficients below e Inthe Main Menu choose Calibration Factors The O3 background correction is determined during zero calibration The O background is the amount of signal read by the analyzer while sampling zero air Before the analyzer sets the O3 reading to zero it stores the value as the O background Thermo Fisher Scientific Operation Calibration Factors Menu The O3 Background screen is used to perform a manual adjustment of the instruments zero background Before performing a background adjustment allow the analyzer to sample zero air until stable readings are obtained The display shows the current O3 reading This reading is the O3 background The next line of the display shows the O3 background compensation that is stored in memory and is being used to correct the O3 reading The O3 background compensation is a value expressed in the current gas units that is subtracted from the O3 reading to produce the O3 reading that is displayed In the example below the analyzer is displaying 4 4 ppb of O3 while sampling zero air The O3 background compensation is 0 0 ppb That is the analyzer is not applying a zero background compensation The question mark is used to as a prompt to change the background compensation In this case the background compensation must be increased to 4 4 ppb in order for the O3 reading to be at 0 ppb To set the O3
