FD-103

Calibration of FD-103 Overview 

Summary:
A step-by-step tutorial on calibrating your FD-103 gas detector. 

Model: 
FD-103-O2
FD-103-H2S
FD-103-CO
FD-103-CO-LOW

Calibration Frequency: 
At least every 12 months.

Calibration Kit Items Required:

  1. Calibration Gas Regulator (C10)
  2. Tubing
  3. Calibration Gas Bottle

FD-103-O2 = Calibration Gas (N2)
FD-103-H2S = Calibration Gas (H2S)
FD-103-CO = Calibration Gas (CO)
FD-103-CO-LOW = Calibration Gas (CO)

Example: FD-103-CO

Note: The same procedure is for FD-103-H2S just make sure to enter the calibration value of your calibration reference gas concentration.

✅ STEP 1: ZERO Calibration to 0.0 ppm using Fresh Air.

  1. Power on your gas detector and allow 2 minutes for stabilization in fresh air.
  2. Expose the gas detector to fresh air or pure nitrogen for at least 2 minutes. 
  3. If using a N2 gas bottle, use a flow rate of 0.5 LPM.
  4. The gas detector may or may not read precisely 0.0 ppm. 
  5. Press the LEFT and RIGHT buttons together.
  6. The "z" icon will appear on the display and will flash.
  7. Press the RIGHT button until it beeps. This will confirm ZERO calibration.
  8. After 5 seconds, the "z" icon disappears, and the unit will read 0.0 ppm.
  9. Done! 
  10. In the main display screen, the unit will now read 0.0 ppm in fresh air.

✅ STEP 2: SPAN Calibration.

  1. Ensure you first undertake a Zero Calibration.
  2. Hold down the "M" button which is the RIGHT button.
  3. Enter passcode: 1234 by using LEFT button to advance the number and RIGHT button to move to the next digit. Then hold down the RIGHT button until a BEEP.
  4. Press the "M" RIGHT button to advance through the menu options.
  5. Continue until the icon "c" is displayed. This means "calibration".
  6. To confirm this selection, hold down the RIGHT button until a BEEP.
  7. Then, you will notice the "c" icon flashing to indicate you are in calibration mode.
  8. Then, enter the calibration reference gas value of your gas bottle.
  9. Once entered, hold the RIGHT button until a BEEP. 
  10. Now the detector is expecting to receive the calibration gas. Expose the gas analyzer to your calibration reference gas for 2 minutes or until the reading has stabilized. Use a flow rate of 0.5 LPM and connect the gas to the gas detector via the FD-103 calibration cap.
  11. When you enter gas, you will notice the ppm values increasing. When stable or after 2 minutes press and hold the RIGHT button to SAVE the calibration point.
  12. After 5 seconds, you will notice that the "c" icon has disappeared.

  13. The detector is now span-calibrated, and the calibrated value is shown on the main screen. 

✅ STEP 3: Verification

  1. Allow the gas detector to stabilize in fresh air for 5 minutes, confirming it reads 0 ppm in fresh air.
  2. Expose the analyzer to the calibration reference gas to verify the calibration and detection repeatability.
  3. If the gas detector reading is within +/- 2% F.S. of the calibration gas value, this is considered a PASS. For example, FD-103-CO-LOW has a full scale of 100 ppm. The unit was calibrated to a reference gas of 10 ppm. Then, a PASS range is +/-2% of 100 ppm = +/- 2 ppm. Therefore, a PASS is between 8 ppm and 12 ppm.  
  4. Once verified, your unit is properly calibrated and ready for operation.
  5. 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.

 Example: FD-103-O2

 

✅ STEP 1: SPAN Calibration to 20.9% in Fresh Air

  1. Power on your oxygen gas detector and allow 2 minutes for stabilization in fresh air. 
  2. Hold down the "M" button which is the RIGHT button.
  3. Enter passcode: 1234 by using LEFT button to advance the number and RIGHT button to move to the next digit. Then hold down the RIGHT button until a BEEP.
  4. Press the "M" RIGHT button to advance through the menu options.
  5. Continue until the icon "c" is displayed. This means "calibration".
  6. To confirm this selection, hold down the RIGHT button until a BEEP.
  7. Then, you will notice the "c" icon flashing to indicate you are in calibration mode and show 20.9%, the target calibration value.
  8. Press and hold the RIGHT button to SAVE the calibration point.
  9. After 5 seconds, you will notice that the "c" icon has disappeared.

  10. The detector is now span-calibrated to 20.9%, and will display 20.9% in fresh air.

✅ STEP 2: ZERO Calibration to 0.0 ppm using Fresh Air.

  1. Once calibrated to fresh air, 20.9%, proceed next to zero calibration.
  2. Hold down the "M" button which is the RIGHT button.
  3. Enter passcode: 1234 by using LEFT button to advance the number and RIGHT button to move to the next digit. Then hold down the RIGHT button until a BEEP.
  4. Press the "M" RIGHT button to advance through the menu options.
  5. Continue until the icon "z" is displayed. This means "zero calibration".
  6. To confirm this selection, hold down the RIGHT button until a BEEP.
  7. The "z" icon will flash. 
  8. Expose the gas detector to pure nitrogen for at least 2 minutes. 
  9. If using a N2 gas bottle, use a flow rate of 0.5 LPM.
  10. The gas detector may or may not read precisely 0.0 ppm. 
  11. Then, press the RIGHT button to save the zero calibration point until it beeps. This will confirm ZERO calibration.
  12. After 5 seconds, the "z" icon disappears, and the unit will read 0.0 ppm.
  13. Done! 

✅ STEP 3: Verification

  1. Allow the oxygen detector 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 detector logbook. Place a reminder calibration date sticker on the unit for the next calibration event.
