COMPETENCY BASED PERFORMANCE CHECK-OFF #1 of 2
Employee Name:
Date of Check-Off:
Supervised by:
1. Turn Power on.
Use only the calibration circuit supplied (P/N 415-0000).
Check
2. Connect the barbed fitting to standard oxygen tubing.
3. Run
wall
O
2
through the cal. circuit @ 0.5 LPM.
4. Connect the luer connector of the calibration circuit to the sample inlet of the AeroNOx
.
5. Allow the O
2
reading to stabilize for 2 - 4 minutes. Calibrate oxygen sensor @ 100% by using the
calibration screwdriver to adjust the calibration potentiometer
.

6. Zero the NO sensor by depressing and holding the NO zero button down.
ZERO NO
appears on the
screen. The sensor is zeroed when the word

appears.
7. Zero
the
NO

8. Disconnect calibration circuit from the AeroNOx
.
9. Disconnect the O
2
and attach NO
2
calibration gas to the calibration circuit.
10. Connect the calibration circuit to the AeroNOx
as in Step 4.
11. Run the
NO
2
cal. gas @ 0.5 LPM
. Re-attach calibration circuit as in Step 5. Allow the NO
2
reading
to stabilize for 2 - 4 minutes. Adjust the NO
2
potentiometer on the front panel with the calibration
screwdriver until the reading matches the chemist’s reported NO
2
concentration on the NO
2
calibration gas tank.

12. Disconnect the NO
2
calibration gas, and run oxygen through the calibration circuit @
0.5 LPM
until
both sensors read zero.
CALIBRATE NO SENSOR
13. Disconnect the calibration circuit from the AeroNOx
.
14. Disconnect the O
2
and attach NO calibration gas, run
the NO cal gas @ 0.5 LPM
. Re-attach the
calibration circuit as in Step 4. Allow the NO reading to stabilize for 2 - 4 minutes. Adjust the NO
potentiometer on the front panel with the calibration screwdriver until the reading matches the
chemist’s reported NO concentration on the NO calibration gas tank.
15. Disconnect the calibration circuit and allow room air to be sampled into the AeroNOx
until the NO
and NO
2
displays return to zero and the Oxygen sensor reads 21%. This will flush out any calibration
gas remaining in the AeroNOx
sampling circuit after calibration. This step will help ensure the
longevity of the AeroNOx
sensors.

AeroNOx
is calibrated and ready for use.
