I'm pretty sure that back when my FTS4050 was still working
it didn't care one little bit about orientation. Perhaps
yours has lost its magnetic shielding, and is reacting to
the change in the orientation of the Earth's magnetic field?
The C'beam standard package in the FTS4050 is an FTS5000 which
was designed to be used in all sorts of 28V applications, including
portable standards and avionics.
