STEP 1: SPAN Calibration to 20.9% oxygen in fresh air.

  1. Power on the gas monitor and allow 2 minutes to stabilize in fresh air.
  2. Check the reading: No calibration is needed if it's within ±0.1% of 20.9%.
  3. For calibration to precisely 20.9%, proceed to the next steps.
  4. Press the "OK" on the remote control to go to the Menu Screen.
  5. Select "Gas Calib" or sometimes called "Gas Check".
  6. Press "EDIT" then enter passcode 1111 then press "OK".
  7. Select your sensor, in this case, the "O2" sensor.
  8. Then, a screen called "Standard Set" appears. Press "OK".
  9. Go to the row that shows 20.9%  under "Std.". Highlight that row and then press "OK".
  10. Then, the "Test" value will adjust to "20.9".
  11. The analyzer is now calibrated to 20.9% oxygen in fresh air.
  12. Done! 
  13. Return to the main display by pressing the top left "return" button. 

STEP 2: ZERO Calibration to 0.0% oxygen using Nitrogen Gas.

  1. Expose the gas analyzer to 100% Nitrogen Gas for at least 2 minutes. The gas monitor will approach 0.0%.
  2. Ensure you are using a flow rate of 0.5 LPM and the FD-60 calibration cap.
  3. Press the "OK" to go to the Menu Screen.
  4. Use the remote control arrows. Go down and select "Gas Zero" then press the "OK" button.
  5. Select the gas sensor you wish to zero calibrate by pressing "OK". In this case, select "O2".
  6. Then press Save by pressing the "OK" button again.
  7. Done!
  8. Remove the nitrogen gas supply and allow the monitor to stabilize back at 20.9% in fresh air.
  9. The analyzer is now zero-calibrated.

STEP 3: Verification

  1. Allow the oxygen analyzer to stabilize in fresh air for 5 minutes, confirming it reads 20.9%.
  2. Once verified, your unit is properly calibrated and ready for operation.
  3. Don't forget to document the calibration event in your gas analyzer log book. Place a reminder calibration date sticker on the unit for the next calibration event.
