B. scanning all the IR wavelengths as they pass through the sample cell. C. measuring intensity of specific UV energy as it passes through a sample cell. D. scanning all the wavelengths as they pass through the sample cell. 2.During a linearity test the XSTREAM CO/CO2 analyzer measured 12.5%CO2 as compared to a calculated predicted concentration of 13.5%. The error at this concentration is A. 1% B. 4% C. 4% D. 6% 3.Explain why the manufacturer is likely using a magnetic reed switch to navigate the HMI instead of a conventional push-button design. Short answer: 4.What does "full scale" refer to in this instrument? Short answer: 5.What is "span gas" and what does it do to adjust the analyzer? Short
