Hi Magnus:

I think some labs don't think about 90 degree turnovers, for example:

I've heard that the xtal oscillator cal procedure for some HP test
equipment says that the instrument should be in the same position as when
it's operating.  For heavy rack equipment that means you lay on a
mechanics creeper when making the adjustment rather than flipping the
instrument 90 degrees on a bench.

Have Fun,
