Zero Calibration

1. Attach tubing between the nitrogen (0ppm 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 0ppm CO2 on the screen.

4. Press the Mode button until the "CALI" icon flashes.

5. Press Enter to enter the "Zero" calibration mode. The "CALI" icon and

"ZEro" should be displayed on the screen.

6. Press and hold the Mode button for at least 10 seconds until "Calibrating"

and "CO2" are flashing simultaneously.

7. Zero calibration will begin. After approximately 5 minutes, the LCD will

display either "PASS" or "FAIL". If the LCD reads "FAIL", repeat the steps

again.

8. Press Enter. The display should now show 0ppm. Remove the nitrogen

cylinder.
