Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

The analog voltage output should measure 80% of the voltage range selected. (e.g. 4.00VDC if

0-5V output is selected.) The readings on the front panel display should be equal to the expected NO and NOx concentrations entered in the procedure given in Table 7-13. See the Troubleshooting Section 9.2.8 if there are problems. Also see the Calibration Quality Check procedure Section 7.8.

After the zero and the 80% URL points have been set, generate five approximately evenly spaced calibration points between zero and 80% URL without further adjustment to the instrument. Allow the instrument to sample these intermediate concentrations for about 10 minutes each and record the instrument NO and NOx responses.

Plot the analyzer NO and NOx responses versus the corresponding calculated concentrations to obtain the calibration relationships. Determine the straight line of best fit (y = mx + b) determined by the method of least squares.

After the best-fit line has been drawn for the NO and the NOx calibrations, determine whether the analyzer response is linear. To be considered linear, no calibration point should differ from the best-fit line by more than 2% of full scale.

7.6.5.3 GPT - NO2 Calibration Procedure

The M200AU computes the NO2 concentration by subtracting the NO from the NOx concentration. Unlike analog instruments, this difference is calculated by the M200AU's internal computer software. It is extremely unlikely that the NO2 concentration will be in error if the NO and NOx channels are calibrated correctly. Therefore this procedure is a confirmation that the NO2 subtraction algorithm in the computer is operating correctly.

NOTE

During this procedure do not make any adjustments to the instrument.

1.Generate a NO concentration near 90% of the URL. Dilution air and O3 generator air flows should be the same as used in the calculation of specified conditions of the dynamic parameter according to Section 7.6.4. Sample this NO concentration until the NO and NOx responses stabilize. Record the NO and NOx concentrations.
