Bump Testing a GX-2012 40
If one or more of the sensors fails the fresh air adjustment, the SDM-2012
will abort the bump test and will not apply calibration gas. If this happens,
the BUMP T LED will flash red indicating a failure and the following screen
will appear indicating which channels passed and failed the fresh air
adjustment with a P (pass) or an F (fail). In the following examples, the CO
channel failed.

defined by the GAS TIME bump test parameter.
