69. PM For a span calibration it is recommended to perform a span calibration to the value you will be measuring i e 10 000 ppm The EVM will derive CO values to achieve greater accuracy over either the 0 5 000 ppm range or the 0 20 000 ppm range The method used is based on the span gas that is used for calibrations If a span gas less than 5 000 ppm is used then CO values will be derived to achieve greater accuracy in the 0 5 000 ppm range NOTE This may lead to reduced accuracy between 5 000 ppm and 20 000 pprn 1f a span gas equal to or greater than 5 000 ppm is used then the CO values will be derived to provide better accuracy over the 0 20 000 ppm range which may lead to reduced accuracy over the narrower 0 5 000 ppm range O2 Accuracy The range for O sensor is 0 30 with a typical span cal of 20 9 074 300 RevE EVM Series 69 Placement and calibration of sensors Calibrating CO2 AND O2 gt 1 6 074 300 RevE Calibrating a zero cal and span cal for CO or for 0 sensor Connect one of the following gases with the regulator and inert tubing e N gas used for zero cal e COQ calibration gas e Room air for 0 calibration gas e 20 9 Attach the regulator and tubing to the gas cylinder Place the Cal cup over the Air inlet cover and slide the tubing over the black air inlet casing From the start screen press W Arrow to select Calibration and press Enter In the Calibrati
