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.
