briefly appear followed by the CALIBRATION LIST screen being re-displayed.

If the sensor’s output is low, but still usable, then the message “Good Calibration WARNING Low Sensor” will appear. The sensor will now be marked as being Low in the DIAGNOSTICS screen.

If the sensor’s output is too low to be usable, then the message “Bad Calibration Sensor End of Life, Entry Not Saved” will appear followed by the CALIBRATION LIST screen being re-displayed. The sensor will now be marked as being BAD in the DIAGNOSTICS screen.

6. Turn OFF regulator and remove gas cylinder.

5.9 NO2 Sensor Calibration

This procedure spans the optional nitrogen dioxide sensor to a known gas level.

Material Required:

• Calibration Kit, P/N 24-7059

• Gas Cylinder: 100 ppm NO2 in Nitrogen, P/N 24-1157

Procedure:

1.If not already done, turn ON the analyzer and display the CALIBRATION LIST screen per Section 5.2.

2.Use the buttons to highlight NO2, and then press ENT to display the CALIBRATE NO2 screen.

“Measured” is the current NO2 reading, while “Applied” is a known NO2 level that will be applied for calibration purposes.

3.Attach a 100 ppm NO2 cylinder to the regulator of the calibration fixture shown in Figure 5-2on Page 5-14.

4.Use the and buttons to enter an Applied value that exactly equals the concen- tration stamped on the NO2 cylinder.

The calibration range is from 9 to 150 ppm. An attempt to calibrate outside this range will
