[ARC5] Oscope Question

[Fuqua, Bill L]

   Has this scope always done this and what model scope is it?

I have noticed something interesting with an oscilloscope I have.  With no signal input, down at the lower right hand corner the trace takes a downward dip, and if you adjust the vertical position of the trace still lower the trace bends up a bit and kind of resembles an S-curve at the end.

Any of y'all have any idea what this might be?  The scope works fine otherwise.

Thanks,
