Warning: You must be in a well‐ventilated area before starting Span Calibration.
Breathing 4% CO2 gas in an enclosed area can result in dizziness, shortness of
breath, or unconsciousness.
Device cannot be span calibrated above 3,000 ft. (900m) altitude.
1. Attach tubing between the 4% CO2 gas cylinder and the
calibration port.
2. Turn on the gas regulator. Flow rate should be between
0.15‐0.3 liters per minute.
3. Wait until the CO2 reading on the SEU settles
consistently at or near 4% CO2 on the screen.
4. Both Alarm 1 and Alarm 2 will sound.
5. Press the Mode button until the "CALI" icon flashes.
6. Press Enter 2 times to enter the "SPAn" calibration mode. The "CALI" icon and
"SPAn" should be displayed on the screen.
7. Press and hold the Mode button for at least 10 seconds until "Calibrating" and
"CO2" are flashing simultaneously.
8. Span calibration will begin. After approximately 5 minutes, the LCD will display
either "PASS" or "FAIL". If the LCD reads "FAIL", repeat the steps again.
9. Press Enter to complete calibration. Remove the CO2 cylinder.
10. To reset the alarm, you must disconnect the SEU from the power source. Wait
a few seconds, then plug it back in again.
If your unit fails either "ZEro" or "SPAn" calibration, please
follow the procedure again before calling support.
