While being used, the sensor reading can become impacted by other substances in the air. A zero calibration is to restore your sensors to a reading of 0, ensuring no other substances are impacting the sensor, hence the need for it to be in the fresh air environment. If your monitor is still not reading as expected after a span calibration, there may be a fault that requires more than a calibration. I would recommend sending this to your local service centre, where they will be able to diagnose the fault Thanks!
can someone explain why we have to do zero calibration.
and next thing. when we do span calibration but the nubmers are not correct. What do we do

Would it hurt to use a 0.5 L/M regulator instead of the 0.25 L/M?
Hello Kyle,
Thanks for your question. A 0.5 l/m may be used on this particular instrument but the 0.25 l/m is the recommended regulator to use.
can we adjust the span gas ?
Hi Mohammad, the span gas can be adjusted but this would have to be done by MSA-trained personnel and using Link Pro Software and the dongle.
@@Frontline-safetyCoUk do u know the factory code to enter the setting of this altair 4x ?
@@mohammadrizalbinsupian430 This isn't something we're able to advise on, access to these settings are for official MSA service providers.
