How to Manually Bump Test the Altair 4XR
Bump testing is crucial in the daily use of your MSA Altair 4XR and should be actioned in accordance with the manufacturer’s guidelines and any site or company specific procedures. We have a complete guide to bump testing your gas detectors, which you can read here.
Before you bump test the unit ensure you have the correct concentration of gas and that the cylinder is not past its expiration date. To bump test your Altair 4XR manually you’ll also need a suitable regulator, tubing and the calibration cap.
Attach the tubing on to the regulator and screw the regulator to the calibration gas bottle and ensure the valve is closed for now. Attach the calibration cap to the front of the monitor.
To select the bump test mode, press the DOWN arrow. The screen will show BUMP TEST and you should select the middle button to proceed. Now turn the valve on the regulator to release the gas. The sensors should start to respond and you should see values on the screen similar to those on
your gas cylinder.
Once it’s successful the screen will show BUMP PASS and the checkmark will appear on the screen. The red LED which previously indicated that the unit required bump testing will now turn green. The checkmark symbol will display on the normal operation mode screen and the LED will flash
green for 24 hours after a successful bump.
