RAE Systems QRAE II Calibration Guide:

Want to calibrate the RAE Systems QRAE II? Here's how:

  1. Turn the RAE Systems QRAE II on in normal reading mode. Do this by pressing and holding the power button on the left.

  2. Give the monitor a five minutes to warm up the sensors. To enter calibration mode, press and hold the top left and top right buttons for 5 seconds.

  3. If you gave the monitor a password, enter it here. Press the yes button on the right to continue. The next screen will ask if you want to calibrate it; press the yes button again to accept. Make sure you are in a fresh air environment and press the yes button one more time to start the fresh air calibration.

  4. Open the valve on your (1 lpm) 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. Once the monitor is done with the fresh air calibration, it will ask if you want to multiple sensor calibration. Accept by pressing the yes button. Press the yes button again to start calibration.

  7. Screw the calibration adapter onto the monitor and open the regulator to allow gas to flow.

  8. Make sure your calibration gas values on the screen match what is on your calibration gas cylinder!

  9. Close and unscrew the regulator then unscrew and detach the calibration adapter from the monitor. Press the left power button until "back" is selected and press the yes button on the right. Do this one more time to get back to normal reading mode.

  10. Congratulations! You have officially calibrated your RAE Systems QRAE II gas monitor. Make sure to record these readings in your calibration log!
