Figure 6-10. NO Sensor Calibration
5. Adjust regulator for a flow meter indication of approximately 2 SCFH.
Wait until the measured reading stabilizes (approximately 3 minutes),
and then press
ENT
to calibrate the NO Measured value to that of the
applied value. The message “Good Calibration” should briefly appear
followed by the CALIBRATION LIST screen being re-displayed.
NOTE:
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.
NOTE:
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 the gas cylinder.

Sensor Calibration
This procedure spans the optional nitrogen dioxide sensor to a known gas
level.
6.10.1. Material Required
•
Calibration Kit
(P/N 0024-7059)
•
Gas Cylinder
(100 ppm NO
2
in Nitrogen, P/N 0024-1157)
6.10.2. Procedure
1. If not already done, turn ON the analyzer and display the
CALIBRATION LIST screen (refer to Calibration on page 66).
2. Use the ▲▼ buttons to highlight NO
