Gas Type
The 2A sensor exhibits different sensitivities to different gases. The default gas is set to air.
Air and dry nitrogen are approximated to have the same sensitivity and using either does not
require any compensation. For users who wish to measure the pressure of Argon gas, the MX2A
includes an Argon correction option.
To change the MX2A between air/nitrogen and argon modes:
Navigate to the calibration screen.
Press DOWN seven times.
Press ENT to unlock the gas type screen.
Press UP or DOWN to change between the gas modes.
When the appropriate mode is selected, press ENT to save and lock the change.
