Moly Converter Efficiency - Teledyne 200A Instruction Manual

Teledyne API Model 200A NO
Plot the analyzer NO and NO
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 NO
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.
7.8.5.3 GPT - NO
The M200A computes the NO
Unlike analog instruments, this difference is calculated by the M200A's internal computer
software. It is extremely unlikely that the NO
procedure is a confirmation that the NO
correctly.
During this procedure do not make any adjustments to the instrument.
1. Generate an NO concentration near 90% of the URL. Dilution air and O
flows should be the same as used in the calculation of specified conditions of the dynamic
parameter according to Section 7.8.4. Sample this NO concentration until the NO and NO
responses stabilize. Record the NO and NO
2. Turn on and adjust the O
the NO concentration to about 10% of full scale. This will be equivalent to 80% of the URL
of the NO
NO concentrations.
