Calibration
5. Adjust regulator for a flowmeter indication of approximately 2 SCFH.
Wait until the Measured reading stabilizes (approximately 3 minutes),
and then press ENT to calibrate the NO
2
Measured value to that of the
Applied value. The message “Good Calibration” should 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.
5.10 CO-HI Sensor Calibration
This procedure spans the optional carbon monoxide high sensor (4,001 to
20,000 ppm) to a known gas level.
Material Required:
Calibration Kit, P/N 24-7059
Gas Cylinder: 4,000 ppm CO in Air, P/N 24-1155
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 CO-HI, and then press ENT to display
the CALIBRATE CO-HI screen.
“Measured” is the current CO reading, while “Applied” is a known CO
level that will be applied for calibration purposes.
3. Attach a 4,000 ppm CO cylinder to the
regulator of the calibration fixture shown in
Figure 5-2 on Page 5-14.
4. Use the and buttons to enter an
Applied value that exactly equals the concen-
tration stamped on the CO cylinder.
The calibration range is from 250 to
11,000 ppm. An attempt to calibrate outside
