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

Sample Pressure

The pressure in the sample inlet line is measured by a solid state pressure sensor which measures absolute pressure. This pressure typically runs 0.5" or so below atmospheric pressure due to the pressure drop in the sample inlet lines and valves.

NOx, NO Slope and Offset Values

The coefficients of 2 (NOx and NO) straight line equations (y = mx + b) determine the calibration of the M200AU. The slope parameter(m) can be thought of as a gain term which determines the steepness of the calibration curve. The offset parameter (b) compensates for differences in the background signal of the NO and NOx channels.

The values of these parameters can be used to determine the quality of the calibration. These 4 parameters contain valuable information about the quality and validity of the calibration. For example, the NO and NOx slope values should not differ by more than .1 from each other. Larger values indicate a flow imbalance such as a leak or problems with the molybdenum converter. Refer to Section 7.8 Calibration Quality for details on how to use these values.

Time

This is an output of the M200AU's internal time of day clock.

5.2.2 CAL, CALS, CALZ, Calibration Functions

The calibration and zero/span checking of the M200AU analyzer is treated in detail in Section 7, Table 7-1 summarizes types of calibration. The basic function of each of these keys is described here. When any of the CAL buttons are pressed (or whenever the instrument enters the CAL mode), the adaptive filter is activated. This allows the instrument to respond rapidly to concentration changes regardless of their magnitude.

5.2.2.1 CAL, CALS, CALZ

These keys control the calibration functions of the analyzer. In the CAL mode the analyzer can be calibrated without switching on the zero valve or the span valve. If the analyzer has the Zero/Span valve option, there will be CALZ and CALS buttons also. These buttons operate the Zero/Span valves. The setup of these options is covered in Section 6.3, and operation is explained in Section 7.
