FD-600M

Calibration of FD-600M

Summary:
A step-by-step tutorial on calibrating your FD-600M datalogger analyzer.  

Model:
FD-600M (all versions except O2)

Calibration Kit Items Required:

  1. Calibration T-piece & Tubing
  2. Calibration Gas Regulator (C10)
  3. Calibration gas for your target gas model (i.e. CO, H2S, EX, 4GAS, etc..)

✅ STEP 1: ZERO Calibration to 0 ppm, 0.0 ppm or 0.00 ppm.

  1. Power on the analyzer and allow 120 seconds for stabilization in fresh air.
  2. Expose the gas analyzer to fresh air or pure nitrogen for at least 1-2 minutes. 
  3. If using a gas bottle, use a flow rate of 0.5 LPM and a T-piece as recommended.
  4. The gas analyzer may or may not read precisely 0 ppm. Depending on the model, it may or may not read 0.0 or 0.00 ppm. To zero calibrate and make it read exactly 0 ppm, 0.0 ppm, or 0.00 ppm, undertake the following steps.
  5. Select "GasZero" from the Menu Screen. 
  6. Highlight the gas you would like to ZERO.
  7. Press the "ZERO" button to confirm the zero value.
  8. When complete, “CONFIG SUCCESS” is displayed. 
  9. In the main display screen, the unit will not read 0 ppm in fresh air.

✅ STEP 2: SPAN Calibration.

  1. Expose the gas analyzer to your calibration reference gas for 1-2 minutes or until the reading has stabilized. Use a flow rate of 0.5 LPM and a T-piece as recommended.
  2. Select "GasCalib" from the Menu Screen.
  3. Enter passcode: 1111.
  4. Enter the span reference gas value for calibration you are using (left column).
  5. The current reading appears in the right column.
  6. Press the middle button "Calib" to confirm the calibration gas concentration.
  7. Press the middle button ">>" to save the span calibration
  8. Wait for the "CONFIG SUCCESS!" confirmation

✅ STEP 3: Verification

  • Allow the analyzer to stabilize in fresh air for 3-4 minutes, confirming it reads 0ppm in fresh air. Expose the analyzer to the calibration reference gas to verify the calibration and detection repeatability.
  • Once verified, your unit is properly calibrated and ready for operation.
