Step

Number Action Comment

1. Scroll the TEST function

menu until the NOX

SLOPE is displayed.

The SLOPE value for NOX should be 1.0  0.3. If the value is

not in this range, check Section 9.1.6. If the SLOPE value is

in the acceptable range the instrument will perform optimally.

2. Scroll the TEST function

menu until the NOX

OFFSET is displayed.

This number should be near zero. A value of 0.0 50

indicates calibration in the optimal range. This number

already has the AutoZero value subtracted out and is mainly

the background signal due to the molybdenum converter. If

the OFFSET value is outside this range, check Section 9.1.6.

3. Scroll the TEST function

menu until the NO

SLOPE is displayed.

The SLOPE value for NO should be 1.0  0.3. If the SLOPE

is in the acceptable range the instrument will perform

optimally. If the value is not in this range, check

Section 9.1.6.

NOTE: The NO and NOX slopes should be equal within  0.1.

4. Scroll the TEST function

menu until the NO

OFFSET is displayed.

The instrument will now display the NO OFFSET value. It

should also have a value near zero (0.0  50). This number

already has the AutoZero reading subtracted out and should

be near zero. If the OFFSET value is outside this range, check

Section 9.1.6.

7.11. Converter Efficiency Compensation

The converter efficiency factor compensates NO2 readings for converter efficiency. The NO2

component of the NOX reading is also compensated when instrument is in switching mode. An

efficiency factor of 1.0 disables efficiency compensation, acceptable values are .80 to 1.20.

There are some fault conditions that can be revealed by a NO2 channel linearity check, such as a

faulty switching valve or a partially plugged converter. For the converter to operate properly

there should be at least a few percent oxygen present in the sample stream.

There are 2 ways to enter the NO2 converter efficiency.

Method 1 is covered in Table 7-12.
