  • MSA Solaris Calibration Guide


    1. Turn the MSA Solaris on in normal reading mode. Do this by pressing the top round button, located on the right side of the monitor.
    2. Once the MSA Solaris is in normal reading mode, you need to send it into calibration mode. Do this by pressing and holding the lower triangle button until it beeps at you and the screen asks you to zero the monitor.
    3. Now that the screen is asking for confirmation, press the top round circle button once to confirm. This will send the monitor into zeroing mode. 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, press the top round button again to confirm. Screw the calibration adapter in to your gas detector. Once it is screwed 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 MSA Solaris. The screen will go back to normal reading mode within a few seconds.
    9. Congratulations! You have officially calibrated your MSA Solaris gas monitor. Make sure to record these readings in your calibration log!
