How to calibrate the BW Technologies GasAlertMicroClip X3

  1. Turn the GasAlertMicroClip X3 on in normal reading mode. Do this by pressing the only button, located top right of the screen.
  2. Once the GasAlertMicroClip X3 is in normal reading mode, you need to send it into calibration mode. Do this by pressing and holding the power button down until it turns off. KEEP HOLDING THE POWER BUTTON.
  3. Eventually, the screen will come up saying hold to calibrate. Hold the button until the screen begins the zeroing process. Now is a good time to set the monitor down, and grab your calibration gas, regulator, and calibration adapter.
  4. Open the valve on your regulator. This is a very important step so you do not ruin your calibration gas cylinder. Now screw it in to your calibration gas cylinder. Close the regulator once you hear gas spewing out of it. This is the signal to know your regulator is good to close. Continue screwing in the regulator until it stops. Do not overturn it.
  5. Attach the tubing to the hose barb on your regulator. Make sure the tubing is also connected to your calibration adapter.
  6. Wait for the screen to come up asking for you to apply calibration gas. Once this screen comes up, clip the calibration adapter on to your gas detector. Once it is clipped on, turn on your gas.
  7. Make sure your calibration gas values on the screen match what is on your calibration gas cylinder!
  8. Once the calibration procedure is completed, turn your gas off and remove the calibration adapter from the GasAlertMicroClip X3. The screen will go back to normal reading mode within a few seconds.
  9. Congratulations! You have officially calibrated your BW Technologies GasAlertMicroClip X3 gas monitor! Make sure to record these readings in your calibration log!
