Abstract
A system, method, and apparatus for certifying an end-of-train device pressure calibration is provided. The system includes a pressure calibration device configured to output a regulated pressure; and an end-of-train device comprising: a brake pipe interface adapted to receive the regulated pressure from the pressure calibration device; and a pressure sensing device configured to obtain a measured pressure by measuring the regulated pressure. At least one of the pressure calibration device and the end-of-train device comprises at least one controller configured to determine a calibration certification result based at least partially on a difference between the measured pressure and the regulated pressure.
