Altair 4xr Calibration

[Tiana Dubree]

Keepingyour gas detectors properly maintained is absolutely vital to ensure the safety of those relying on them. Part of such maintenance in manually calibrating them. The importance of calibrating gas detectors is fully explored in our guide which you can read here.

You will see the values on the screen starting to rise and calibration will take as long as required by the sensors and will finish once a sufficient amount of gas has been detected.

The detector will beep, SPAN PASS will flash on the screen and the tick symbol will appear on the right hand of the monitor. You can now close the gas off, remove the calibration cap and proceed with normal measurement mode.

As with any maintenance of gas detectors, please ensure you're complying with the manufacturer's guidelines and any site and/or company specific procedures. If you'd like more information on the Altair 4X, gas detectors in general or advice on maintenance, please get in touch with our team via the Contact Us page.

MSA recommends calibration at least every six months; however, many countries and/or organizations have their own calibration guidelines. The ALTAIR io 4 calibration interval can be configured to adapt to these requirements.

During zero calibration, the O2 sensor is also span calibrated to 20.8% O2 fresh air, adjusting the calibration curve as needed. During span calibration, the O2 sensor's accuracy is checked against a known oxygen gas concentration without adjusting the calibration curve.

The calibration procedure adjusts the span value for any sensor that passes the calibration test; sensor span values that fail calibration are left unchanged. Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

If a calibration is unsuccessful for two subsequent calibrations, the device will communicate an end of sensor life warning to the user. Note that a span calibration can fail for many reasons other than a sensor at the end of its life. If a span calibration failure occurs, factors such as remaining gas in the calibration gas cylinder, gas expiration date, security of the calibration cap, etc. should be verified, and a calibration should be repeated prior to replacing the sensor.

Want to calibrate the MSA Altair 4 or MSA Altair 4X? Here's how:

1. Turn the MSA Altair 4 and MSA Altair 4X on in normal reading mode. Do this by pressing and holding the center button.

2. Once the MSA Altair 4 and MSA Altair 4X is in normal reading mode, you need to send it into calibration mode. Do this by pressing and holding right beeps at you and the screen asks you to zero the monitor (sensor refresh on the MSA Altair 4X).

3. Now that the screen is asking for confirmation, press the center 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 center 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 Altair 4 or MSA Altair 4X. The screen will go back to normal reading mode within a few seconds.

9. Congratulations! You have officially calibrated your MSA Altair 4 or MSA Altair 4X gas monitor. Make sure to record these readings in your calibration log!

The MSA Altair 4XR Multiple Gas Detector (LEL, O2, CO, H2S) surpasses industry standards in several crucial areas. Its four-year sensor life is 60% longer than the industry average, while its 24-hour run time exceeds the industry average by 71%. This versatile portable detector is a perfect match for industries ranging from fire fighting to welding, and its digital sensor output makes it less likely to suffer from RF interference. The unit features exclusive MotionAlert, which lets others know if the user has become immobile, and InstantAlert, a manual alarm that alerts others of potentially dangerous situations. This rugged unit is designed to withstand a drop of up to 20 feet and uses less than half as much calibration gas as the industry average.

MSA offers a 34L calibration gas aluminum cylinders to calibrate the Altair 4XR and 5X monitor. The 4-gas mixture in the calibration gas cylinders is certified to be prepared gravimetrically, using NIST traceable weights. The lot number and the nominal value of the gas concentrations in volume, percent by mass, ppm, or volume are specified on the cylinder. There is a shelf life or expiration date to let you know when not to use the gas to calibrate or bump test a monitor. MSA also has a calibration gas recycling program that helps a non-profit organization. The cylinder contains sufficient calibration gas for multiple MSA instrument calibrations, and it requires a regulator (sold separately).

Note: This item ships via UPS Ground due to HazMat restrictions and isn't available for expedited shipping. Calibration gas is not returnable. Please check your selection carefully before ordering.
