How do I calibrate my MSA gas detector?
How do I calibrate the MSA Altair 4X?
- Hold the UP arrow down for 3 seconds until ZERO CAL shows, ensuring you’re in a fresh-air environment whilst doing so.
- This asks if you’d like to go ahead with carrying out a zero calibration.
- Select Yes by pressing the middle button and the Sensor Refresh screen will show.
How often should you calibrate a MSA Altair 5x?
For users who do not wish to develop their own frequency, we recommend they calibrate once a month. For those who “bump test” their instrument prior to each use, the calibration cycle can be extended to three to six months for instruments that successfully pass the bump gas test.
How do you calibrate a portable gas detector?
Best practice is to test the gas monitor with a known concentration of gas before each use (bump test/challenge test). Another way to determine the calibration frequency is to check the response of the gas monitor daily in the intended atmosphere for a pre-determined time (example being 10 days).
How do you calibrate a LEL meter?
Take an LEL sensor and calibrate it to Pentane. If you expose the sensor to Methane gas the instrument will read higher than the true level of methane gas. If though, you calibrate the sensor to methane and then expose the sensor to pentane gas the instrument will read less than the true value of pentane gas.
How do you calibrate a VOC sensor?
To access the CALIBRATION menu, press the MENU key and scroll down to CALIBRATION and press ENTER. Highlight Calibrate VOC and then press ENTER. The measurement capabilities of the instrument and probe will determine what appears in the main MENU and CALIBRATION menu.
Can I calibrate my own gas detector?
To calibrate your own gas detection equipment you may need some additional equipment: A calibration cap to attach your hose to your gas detector. Calibration gas cylinders with the test gas you require (these come in a range of sizes) Regulators and accessories for disposable calibration gas cylinders.
How often does a gas detector need to be calibrated?
every six months
If a gas detector has been subject to high gas concentrations or unusual conditions, it is generally recommended that a bump test or calibration be performed. At a1-cbiss, we recommend that gas detection equipment is calibrated at least every six months for a reliable performance.
What is the difference between bump test and calibration?
A: A bump test is a very brief exposure of a monitor to a gas to help verify that the sensors respond and the alarms are functioning. A calibration is performed by exposing the monitor to a certified concentration of gas for a given time to help verify it provides an accurate reading.
